Neophaeothecoidea Quaedvl. & Crous, Persoonia 33: 27 (2014)
Hyphomycetous, saprobic. Sexual morph: Unknown. Asexual morph: Hyphae in vitro creeping, brown, verruculose, branched, septate, becoming swollen, verruculose, dark brown, or forming a mucoid capsule filled with endoconidia derived from hyphal cells that turn brown and become thick-walled; end cells divide into several endoconidia, which are released upon rupture of the cell wall. Endoconidia medium to dark brown, verruculose to verrucose to warty, thick-walled, ellipsoid to obovoid or obclavate; after liberation swelling, becoming transversely 1-septate, or with several oblique septa, again forming endoconidia, becoming warty with age, the outer layer peels off after endoconidia are released (Adapted from Quaedvlieg et al. 2014).
Type species: Neophaeothecoidea proteae (Crous) Quaedvl. & Crous
Notes: Neophaeothecoidea was introduced by Quaedvlieg and Crous (2014) with N. proteae as type species. N. proteae was previously known as Phaeothecoidea proteae Crous and it was not congeneric with Phaeothecoidea sensu stricto. N. proteae was initially isolated as a coelomycetes and was mistaken for Coniothyrium leucospermi (= Coniozyma leucospermi). Neophaeothecoidea can be differentiated from Coniothyrium based on DNA sequence data.
