Genus ( / ˈ dʒ iː n ə s / ; pl. : genera / ˈ dʒ ɛ n ər ə / ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses . In binomial nomenclature , the genus name forms the first part of the binomial species name for each species within the genus.
78-539: ~70 worldwide (see text) Morchella , the true morels , is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales ( division Ascomycota ). These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their caps . Morels are prized by gourmet cooks, particularly in Catalan and French cuisine , but can be toxic if consumed raw or undercooked. Due to difficulties in cultivation , commercial harvesting of wild morels has become
156-464: A basal species from Turkey later shown to be sister to Morchella rufobrunnea . A study by Clowez described over 20 new species in 2012, while later in the same year, another study by Kuo and colleagues described 19 species from North America . However, several of these newly proposed names later turned out to be synonyms. An extensive taxonomical and nomenclatural revision of the genus provided by Richard and colleagues in 2014, applied names to 30 of
234-446: A fire . Moderate-intensity fires are reported to produce higher abundances of morels than low- or high-intensity fires. This is caused by the soil becoming more alkaline as the result of wood ash combining with water and being absorbed into the soil which triggers the morels to fruit. Alkaline soil conditions which trigger fruiting have been observed and exploited with small-scale commercial cultivation of morels. Where fire suppression
312-557: A species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in the nomenclature codes , which allow each species a single unique name that, for animals (including protists ), plants (also including algae and fungi ) and prokaryotes ( bacteria and archaea ), is Latin and binomial in form; this contrasts with common or vernacular names , which are non-standardized, can be non-unique, and typically also vary by country and language of usage. Except for viruses ,
390-622: A bountiful morel crop the next spring!" Morels are a feature of many cuisines, including Provençal . Their flavor is prized by chefs worldwide, with recipes and preparation methods designed to highlight and preserve it. As with most edible fungi , they are best when collected or bought fresh. They are sometimes added to meat and poultry dishes and soups, and can be used as pasta fillings. As morels are known to contain thermolabile toxins, they must always be cooked before eating. Morels can be preserved in several ways: They can be 'flash frozen' by simply running under cold water or putting them in
468-414: A brush, after cutting the body in half lengthwise, if needed. Mushroom hunters sometimes recommend soaking morels in a bowl of salt water briefly prior to cooking, although many chefs would disagree. Drying is a popular and effective method for long-term storage, and morels are widely available commercially in this form. Any insect larvae which might be present in the fruit bodies usually drop out during
546-453: A bucket to soak for a few minutes, then spread on a baking tray and placed into a freezer. After freezing, they keep very well with the frozen glaze for a long time in airtight containers. However, when thawed they can sometimes turn slightly mushy, so they are best frozen after steaming or frying . Due to their natural porosity, morels may contain trace amounts of soil which cannot be easily washed out. Any visible soil should be removed with
624-535: A distinct species. Later in the same year, Clowez and colleagues described Morchella palazonii from Spain, while Voitk and colleagues described Morchella laurentiana from Canada and Morchella eohespera , a cosmopolitan species present in several continents. In an extensive phylogenetic and morphological study from Cyprus in 2016, Loizides and colleagues added two more Mediterranean species, Morchella arbutiphila and Morchella disparilis , and resurrected Morchella dunensis as an autonomous species. In
702-541: A dozen genealogically distinct species in North America and at least as many in Europe . DNA studies revealed three discrete clades , or genetic groups, consisting of the "white morels" ( Morchella rufobrunnea and M. anatolica ), the "yellow morels" ( M. esculenta and others), and the "black morels" ( M. elata and others). The fire-associated species Morchella tomentosa , commonly known as
780-649: A large-spored species described by American mycologist Charles Peck in 1887. Morchella purpurascens , the purple morel, was first described by Boudier as a variety of M. elata in 1897 based on an 1834 plate by Krombholz, and was recombined as a distinct species in 1985 by Emile Jacquetant. Morchella eximia , a globally-occurring fire-associated species was also described by Boudier in 1910. The old, widely applied name Morchella conica , featuring in many field guides and literature across several countries, has been shown by Richard and colleagues to be illegitimate . About 80 species of Morchella were described until
858-651: A later homonym of a validly published name is a nomen illegitimum or nom. illeg. ; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,
1014-564: A mesh collecting bag, so the spores can scatter as one carries the harvest. Every spring, hundreds of morel enthusiasts gather in Boyne City, Michigan for the National Morel Mushroom Festival, a century-old event. As one observer stated, "if there is a modern, North American reenactment of Geoffrey Chaucer 's Canterbury Tales this is it." Other festivals and hunting competitions in North America include
1092-577: A mountain family was saved from starvation by eating morels. In parts of West Virginia , they are known as molly moochers , muggins , or muggles . Due to the partial structural and textural similarity to some species of Porifera (sponges), other common names for any true morel are sponge mushroom and waffle mushroom . In the Appalachian woodlands, morels have also been called haystacks , or snakeheads . The Finnish vernacular name huhtasieni , refers to huhta , area cleared for agriculture by
1170-739: A multimillion-dollar industry in the temperate Northern Hemisphere , in particular North America , Turkey , China , the Himalayas , India , and Pakistan where these highly prized fungi are found in abundance. Typified by Morchella esculenta in 1794, the genus has been the source of considerable taxonomical controversy throughout the years, mostly with regard to the number of species involved, with some mycologists recognising as few as three species and others over thirty. Current molecular phylogenetics suggest there might be over seventy species of Morchella worldwide, most of them exhibiting high continental endemism and provincialism. The genus
1248-409: A reference for designating currently accepted genus names as opposed to others which may be either reduced to synonymy, or, in the case of prokaryotes, relegated to a status of "names without standing in prokaryotic nomenclature". An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for
1326-694: A row. False morels contain gyromitrin , an organic carcinogenic poison, hydrolyzed in the body into monomethylhydrazine (MMH). Gyromitra esculenta in particular, has been reported to be responsible for up to 23% of mushroom fatalities each year in Poland . The key morphological features distinguishing false morels from true morels are as follows: The fruit bodies of Morchella species are highly polymorphic , varying in shape, color, and size. While in many cases they do not exhibit clear-cut distinguishing features microscopically, this has historically contributed to uncertainties in taxonomy. Discriminating between
1404-447: A solution of water and molasses which are poured over the piles of mulch and then they are allowed to grow undisturbed for several weeks. A solution of wood ashes mixed in water and diluted is subsequently poured over the rows of wood mulch which triggers fruiting of the morels. Morels are known to appear after fires and the alkalinity produced by wood ash mixed with water initiate fruit body formation for most species of morels. In 2021 it
1482-427: A taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question. In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name . An invalidly published name is a nomen invalidum or nom. inval. ; a rejected name is a nomen rejiciendum or nom. rej. ;
1560-455: A total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

When eating this fungus for the first time, it is advised to consume a small amount to minimize any allergic reaction. As with all fungi, morels for consumption must be clean and free of decay. Morels growing in old apple orchards previously treated with

If these areas are overrun by wildfire they often produce a bumper crop of black morels the following spring. Commercial pickers and buyers in North America target recently burned areas for this reason. These spots may be closely guarded by mushroom pickers, as morels are widely regarded as a delicacy and often a cash crop . Due to
2028-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,
2106-474: Is the type species , and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

In 1794, Persoon introduced the term lirella for the furrowed ascomata of the lichen genus Graphis . Between 1805 and 1807, he published two volumes of his Synopsis plantarum Archived 20 May 2011 at the Wayback Machine , a popular work describing 20,000 species of all types of plants. But his pioneering work

His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Initially studying theology at Halle , at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen . He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. He moved to Paris in 1802, where he spent
2340-403: The Himalayas . Early ancestral reconstruction tests by O'Donnell and collaborators postulated a western North American origin of morels and the genus was estimated to have diverged from its closest genealogical relatives Verpa and Disciotis in the early Cretaceous, approximately 129 million years ago (Mya). This date was later revised by Du and collaborators, placing the divergence of
2418-621: The International Code of Zoological Nomenclature ; the earliest such name for any taxon (for example, a genus) should then be selected as the " valid " (i.e., current or accepted) name for the taxon in question. Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to

Totals for both "all names" and estimates for "accepted names" as held in the Interim Register of Marine and Nonmarine Genera (IRMNG) are broken down further in the publication by Rees et al., 2020 cited above. The accepted names estimates are as follows, broken down by kingdom: The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names;

Certain Morchella species ( M. eximia , M. importuna , M. tomentosa and others) exhibit a pyrophilic behaviour and may grow abundantly in forests which have been recently burned by
2652-404: The platypus belongs to the genus Ornithorhynchus although George Shaw named it Platypus in 1799 (these two names are thus synonyms ) . However, the name Platypus had already been given to a group of ambrosia beetles by Johann Friedrich Wilhelm Herbst in 1793. A name that means two different things is a homonym . Since beetles and platypuses are both members of the kingdom Animalia,

Within the yellow and black clades, there are dozens of distinct species, many endemic to individual continents or regions. This species-rich view is supported by studies in Western Europe , Turkey, Cyprus , Israel , China , Patagonia , and
2808-473: The French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or the scientific epithet) of a genus is also called the generic name ; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature , the system of naming organisms , where it is combined with the scientific name of

Morchella species have been called by many local names; some of the more colorful include dryland fish , because when sliced lengthwise then breaded and fried, their outline resembles the shape of a fish; hickory chickens , as they are known in many parts of Kentucky ; and merkels or miracles , based on folklore , of how
2964-586: The accuracy of the original reconstructions, since both species of the ancestral /Rufobrunnea clade are present in the Mediterranean, while M. anatolica is altogether absent from North America. Updated ancestral area reconstructions by Loizides and colleagues using an expanded 79-species data set, have in 2021 refuted the previous hypothesis and designated the Mediterranean basin as the most probable place of origin of morels. Morels can be found in
3042-597: The autumn or winter months rather than spring, which is the typical fruiting season for morels. In the American Pacific Northwest , they can be found from April to August. Efforts to cultivate morels at a large scale have rarely been successful and the commercial morel industry relies on the harvest of wild mushrooms. Although many species within Morchella exhibit continental endemism and provincialism, several species have been phylogenetically shown to be present in more than one continent. So far,

3198-440: The breakthroughs with this project was growing them in a climate controlled environment in conjunction with grass which is involved in stimulating fruiting in the morel mycelium. Cultivation in this manner has been noted to produce superior morels for culinary uses since they can be assured to be insect, slug and dirt free and therefore do not need to be washed and cleaned like foraged morels. Since washing morels can negatively impact

3276-646: The deprecated insecticide lead arsenate may accumulate levels of toxic lead and arsenic that are unsuitable for human consumption. Morels, "almost universally associated with spring," can be found in many habitats. Morel may be more likely to fruit during a period of increasing heat following a chilly period, a preference which is credited for their abundance in areas with cold winters. Black morels ( Morchella elata ) are often found on land that has been disturbed by logging burning. Raw morel mushrooms are 90% water, 5% carbohydrates , 3% protein , and 1% fat . A 100 gram reference amount supplies 31 calories , and

The flavor of morels is not just appreciated by humans; in Yellowstone National Park , black morels are also known to be consumed by grizzly bears ( Ursus arctos horribilis ). Morel hunting is a common springtime activity. Mushroom collectors may carry
3432-554: The first tropical polypores ever described. In 1815, Persoon was elected a corresponding member of the Royal Swedish Academy of Sciences . Persoon was a prolific author of new fungal species, having formally described 2269 in his career. The genus Persoonia , a variety of small Australian trees and shrubs, was named after him. The title Persoonia is also given to a biannual scientific journal of molecular phylogeny and evolution of fungi, published jointly by

Thus in the examples above, the genus Canis would be cited in full as " Canis Linnaeus, 1758" (zoological usage), while Hibiscus , also first established by Linnaeus but in 1753, is simply " Hibiscus L." (botanical usage). Each genus should have a designated type , although in practice there is a backlog of older names without one. In zoology, this
3588-579: The genealogical lineages recognized so far and clarified several synonymities. Also in 2014, Elliott and colleagues described Morchella australiana from sclerophyll forests in Australia , while Clowez and colleagues described Morchella fluvialis from riparian forests in Spain . In 2015, Loizides and colleagues clarified the taxonomy of Morchella tridentina , a cosmopolitan species described under many names, and recombined Morchella kakiicolor as
3666-737: The generic name (or its abbreviated form) still forms the leading portion of the scientific name, for example, Canis lupus lupus for the Eurasian wolf subspecies, or as a botanical example, Hibiscus arnottianus ssp. immaculatus . Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics . The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example,
3744-457: The genus in the late Jurassic, approximately 154 Mya. However, neither of these reconstructions had included Morchella anatolica in the analyses, whose phylogenetic placement remained at the time unresolved. Following genetic testing of isotype collection of M. anatolica by Taşkın and colleagues, this species was shown to nest in the ancestral /Rufobrunnea clade, together with the transcontinental M. rufobrunnea . This cast doubts over
3822-432: The idea that a newly defined genus should fulfill these three criteria to be descriptively useful: Moreover, genera should be composed of phylogenetic units of the same kind as other (analogous) genera. The term "genus" comes from Latin genus , a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum , but
3900-719: The individual species, continent, or region. Trees commonly associated with morels in Europe and across the Mediterranean include Abies (fir), Pinus (pine), Populus (poplar), Ulmus (elm), Quercus (oak), Arbutus (strawberry trees), Castanea (chestnut), Alnus (alder), Olea (olive trees), Malus (apple trees), and Fraxinus (ash). In western North America morels are often found in coniferous forests, including species of Pinus (pine), Abies (fir), Larix (larch), and Pseudotsuga (Douglas-fir), as well as in Populus (cottonwood) riparian forests. Deciduous trees commonly associated with morels in
3978-633: The largest component, with 23,236 ± 5,379 accepted genus names, of which 20,845 ± 4,494 are angiosperms (superclass Angiospermae). By comparison, the 2018 annual edition of the Catalogue of Life (estimated >90% complete, for extant species in the main) contains currently 175,363 "accepted" genus names for 1,744,204 living and 59,284 extinct species, also including genus names only (no species) for some groups. The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles , which have about 1180 genera,

The reasons behind the widespread, cosmopolitan distribution of these species, are still puzzling. Some authors have hypothesized that such transcontinental occurrences are
4134-466: The lizard genus Anolis has been suggested to be broken down into 8 or so different genera which would bring its ~400 species to smaller, more manageable subsets. Christiaan Hendrik Persoon Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a Cape Colony mycologist who made additions to Linnaeus ' mushroom taxonomy . Persoon was born in Cape Colony at

In 1901, Repin reported successfully obtaining fruit bodies in a cave in which cultures had been established in flower pots nine years previously in 1892. More recently, small-scale commercial growers have had success growing morels by using partially shaded rows of mulched wood. The rows of mulch piles are inoculated with morel mushroom spores in
4368-428: The name could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800. However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code. Names with the same form but applying to different taxa are called "homonyms". Although this

He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to donate his herbarium to the House of Orange , in return for an adequate pension for life. The origin of Persoon's botanical interest
4680-417: The result of accidental anthropogenic introductions , but this view has been disputed by others, who suggested an old and natural distribution, at least for some of these species which appear to be linked to indigenous flora. Long-distance spore dispersal has also been suggested as a possible dispersal mechanism for some species, especially those belonging to fire-adapted lineages . It has been suggested that

The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including
4992-497: The specific name particular to the wolf. A botanical example would be Hibiscus arnottianus , a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,

As molecular tools became widely available in the new millennium, a revived interest in the genus commenced and several new species were proposed. In 2008 Kuo described Morchella tomentosa from burned coniferous forests in western North America. In 2010 Işiloğlu and colleagues described Morchella anatolica ,
5538-576: The values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes. Within Animalia, the largest phylum is Arthropoda , with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta). Within Plantae, Tracheophyta (vascular plants) make up
5616-520: The various taxa described is further hindered by uncertainty over which of these are truly biologically distinct. Remarkably, some authors in the past had suggested that the genus contains as few as 3 to 6 species, while others recognised as many as 34. Efforts to clarify the situation and re-evaluate old classical names (such as Morchella elata and others) in accordance to current phylogenetic data have been challenging, due to vague or ambiguous original descriptions and loss of holotype material. In 2012,
5694-429: The virus species " Salmonid herpesvirus 1 ", " Salmonid herpesvirus 2 " and " Salmonid herpesvirus 3 " are all within the genus Salmonivirus ; however, the genus to which the species with the formal names " Everglades virus " and " Ross River virus " are assigned is Alphavirus . As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in
5772-543: The widespread but disjunct distribution of some morel species, especially early diverging lineages like M. rufobrunnea and M. tridentina , may be the result of climatic refugia from the Quaternary glaciation . The ecology of Morchella species is not well understood. Many species appear to form symbiotic or endophytic relationships with trees, while others appear to act as saprotrophs . Tree species associated with Morchella vary greatly depending on
5850-526: Was announced that indoor cultivation of black morels had been successfully achieved after decades of research and experimentation with methods by The Danish Morel Project . The project has been able to cultivate 20 lbs of morels per square yard or around 10 kg per square metre with cost estimates expected to be similar to producing white button mushrooms ( Agaricus bisporus ). Previous attempts at cultivation had managed to produce sclerotia but encountered issues in getting them to reliably fruit. One of
5928-539: Was described by Elias Fries in 1822, from a fir forest in Sweden . Other classical, early-proposed names include Morchella deliciosa , also described by Fries in 1822, Morchella semilibera , the half-free morel, originally described by de Candolle and sanctioned by Fries in 1822, Morchella vulgaris , which was recombined by Samuel Gray as a distinct species in 1821 following a forma of M. esculenta previously proposed by Persoon , and Morchella angusticeps ,
6006-681: Was in the fungi, for which he published several works, beginning with the Synopsis methodica fungorum (1801); it is the starting point for nomenclature of the Uredinales , Ustilaginales , and the Gasteromycetes . Persoon described many polypore species; most were from his own collections in central Europe, while several other tropical species were sent to him from collections made by French botanist Charles Gaudichaud-Beaupré during his circumglobal expedition. These latter fungi are among
6084-478: Was typified by Christiaan Hendrik Persoon in 1794, with Morchella esculenta designated as the type species for the genus. Among early pioneers who took an interest in the genus, were mycologists Julius Vincenz von Krombholz and Émile Boudier , who, in 1834 and 1897 respectively, published several species and varieties, accompanied by meticulously illustrated iconographic plates. The seminal taxon Morchella elata , whose true identity still remains unresolved,
