Type species – Omnidemptus affinis P.F. Cannon & Alcorn
Notes – Omnidemptus affinis was found on leaves of Panicum effusum in Queensland (Cannon & Alcorn 1994, Thongkantha et al. 2009). The sexual morph is characterized by perithecia ascomata, cylindrical to clavate, short pedicellate asci with an obtuse apex and an apical pore that stains dark blue with Melzer’s reagent and fusiform, 1–3-septate, hyaline ascospores (Cannon & Alcorn 1994). The asexual morph is sporodochium-like, with cylindrical, clavate or ellipsoid conidiogenous cells, and falcate, 2-septate conidia, the base of conidia sometimes with an abrupt change in contour to short pedicel-like extension (Hernández-Restrepo et al. 2019).
