This genus is characterized by superficial ascomata usually covered with hairs or setae (6); membranaceous peridium, consisting of several pseudoparenchymatous layers; asci that are clavate or fusiform (with biseriately arranged ascospores) or sometimes cylindrical (with uniseriately arranged ascospores), thin-walled, evanescent and without apical structures; scarce paraphyses that disappear before ascocarps
mature (7); ascospores that are brown or gray-brown (never opaque or black), one celled, with one or sometimes two germ pores, and exuding as a dark, black, sticky mass (8).
with terminal straight hairs, up to 1.5 [micro]m long, black septate surrounding the ostiole.
Ascomycetes that have mycelia characteristically produce fruiting bodies called ascocarps
Emergence of morel (Morchella) and pixie cup (Geopyxis carbonaria) ascocarps
in response to the intensity of forest floor combustion during a wildfrre.
flavus where undeveloped stromata (sexual structure) were found in naturally infected maize ears and developed to ascocarps
with viable ascospores .
This ascomycete produces thin, brilliant orange ascocarps
(the fruiting body of the fungus) that resemble orange peels that stand out in the drab colors of autumn and give the fungus its name.
The most common morphologic feature of this form is the formation of brown-black ascocarps
are fruiting bodies that consist of very tightly interwoven hyphae and asci.
