Type speciesLeucosphaerina indica (Arx, Mukerji & N. Singh) Arx

NotesLeucosphaerina was introduced by von Arx (1987) based on L. indica from dung of Boselaphus tragocamelus in Delh, but lacks sequence data. Malloch (1989) introduced L. arxii fungi from dung of Equus in North Carolina. Summerbell et al. (2011) provided sequence data for L. arxii. The genus is characterized by clavate asci, ellipsoidal, hyaline ascospores with sheaths, and an acremonium-like asexual morphs with solitary or paired tapering conidiogenous cells, septate at the base, bearing small apical clusters of conidia, conidia are ellipsoidal to obovate, hyaline, 1-celled and produced in wet masses (von Arx 1987, Malloch 1989).
