Type speciesCylindrotrichum oligospermum (Corda) Bonord.

NotesCylindrotrichum was introduced by Bonorden (1851) with C. oligospermum as the type species. Reticulascus was introduced by Réblová et al. (2011) for a holomorphic species R. tulasneorum (asexual morph C. oligospermum, Réblová & Gams 1999), the generic type, and R. clavatus (asexual morph Cylindrotrichum clavatum). Réblová et al. (2016b) recommended the use of Cylindrotrichum over Reticulascus given its widespread use, priority, and greater number of names. Cylindrotrichum oligospermum is illustrated in this entry.
