Pseudochaetosphaeronema Punith.

Notes.

Pseudochaetosphaeronema was introduced by Punithalingam (1979), with P. larense as the type species. The members of this genus have been reported as human pathogens, endophytes and saprobes ( Boonmee et al. 2021). Nine epithets are listed in Index Fungorum (2024), i.e. one sexual P. chiangraiense and eight asexual species viz. P. ginkgonis , P. kunmingense , P. larense , P. magnoliae , P. martinelli , P. pandanicola , P. siamense and P. sklodowskacurieae . The asexual morph of Pseudochaetosphaeronema is characterised by globose, conidiomata, monophialidic, cylindrical conidiogenous cells and hyaline, subglobose to oval, aseptate conidia ( De Silva et al. 2022). The sexual morph is characterised by immersed, uni-loculate ascomata, peridium with the cells of textura angularis, unbranched, septate pseudoparaphyses, 8-spored, bitunicate, fissitunicate, short distinct pedicel asci with rounded end and fusiform, 1-septate, guttulate ascospores with pointed ends ( Boonmee et al. 2021).
