Generic description<br />
Habitat terrestrial, saprobic. Ascomata medium to large,<br />
immersed, erumpent to nearly superficial, scattered or in<br />
small groups, usually with a wide papilla, ostiolate,<br />
coriaceous. Peridium composed of small pigmented cells<br />
of textura angularis. Asci 8-spored or fewer, cylindroclavate,<br />
with a furcate pedicel. Hamathecium of trabeculate<br />
pseudoparaphyses. Ascospores brown to dark brown,<br />
cylindrical to nearly clavate with broadly to narrowly round<br />
ends, multi-septate, easily broken into partspores, smooth,<br />
with elongated germ slit in each cell.<br />
Anamorphs reported for genus: none.<br />
