4-405: Sphaeropsidales is an order of Coelomycetes fungi. These are conidial fungi where the conidia form in a growing cavity in the host's tissue. The fruiting structures are spherical with an opening at the apex ( pycnidia ). Four form-families can be distinguished. Sphaeropsidaceae are fungi with pycnidia dark colored, leathery to carbonous, stromatic or non-stromatic generally provided with
8-575: A circular opening. Zythiaceae are fungi with pycnidia as in the Sphaeropsidaceae but light colored instead of dark, and soft or waxy instead of leathery. Leptostromataceae are fungi with hpycnidia shield-shaped or elongated, and flattened. Excipulaceae are fungi where mature pycnidia are somewhat deeply cup-shaped. In the family Sphaeropsidaceae, species of the genus Darluca are hyperparasitic on rusts while species of Cicinnobolus are hyperparasites of powdery mildew . Their mycelium
12-496: Is grown longitudinally in the mycelium of their hosts. Members of this order can produce bisnaphthyl pigments, such as Sphaerolone and dihydrosphaerolone , or 2-hydroxyjuglone .

16-424: The conidia form in a growing cavity in the host 's tissue. The fruiting structures are spherical with an opening at the apex ( pycnidia ) or are disc-shaped ( acervuli ). The formation of conidia in a fruiting body separates this group from the hyphomycetes , who have "naked" conidia. Franz Xaver Rudolf von Höhnel (1852–1920), an Austrian bryologist, mycologist and algologist, was known for his contributions to
