Specific endophyte or saprobic on plants, and human pathogens. Sexual morph: Ascomata scattered, immersed, globose to depressed globose, ostiolate, central to excentric, short cylindrical or erumpent at ostiolar neck. Peridium composed of polygonal to rectangular, thin-walled cells. Hamathecium comprising septate, branched and anastomosed, cellular pseudoparaphyses. Asci cylindrical to clavate, bitunicate, fissitunicate, pedicellate. Ascospores 2-seriate, broadly fusiform, 1- or multi-septate, hyaline, smooth-walled. Spermatia subglobose to ellipsoidal. (Tanaka et al. 2017) Asexual morph: Conidiomata single or gregarious, immersed, globose to collabent, papillate, dark brown to black, unilocular or multilocular; thick-walled composed of cells of textura porrecta, intricata or angularis. Ostiole single, papillate. Conidiophores reduced to conidiogenous cells. Conidiogenous cells discrete, determinate or indeterminate, cylindrical, lageniform, doliiform or ampulliform, hyaline, smooth, with percurrent proliferations. Conidia obovoid, cylindrical, clavate or fusiform, basal or apical cells paler than the median cells, distoseptate or euseptate, thick-walled, base truncate, apex obtuse.
Type – Neohendersonia Petrak.
Notes – Neohendersonia pyriforme was described from Fagus sylvatica in Belgium. Sutton & Pollack (1974) combined Stilbospora kickxii which was stated as a synonym to Neohendersonia pyriforme, into Neohendersonia, and N. kickxii was proposed as the type species. Tanaka et al. (2017) introduced Brevicollum to Noehendersoniaceae and accepted four genera Crassiparies, Medicopsis, Neohendersonia including Brevicollum in this family. Crous et al. (2019b) introduced a new genus Neomedicopsis to the family. The family placement of Mediocopsis is uncertain (Ahmed et al. 2014, Li et al. 2016a), yet Tanaka et al. (2017) suggested that Mediocopsis belongs to Neohendersoniaceae based on the multi-gene phylogenetic analysis.
