Index Fungorum number: IF 7881; 15 morphological species (Species Fungorum 2020), 6 species with sequence data
Saprobic on wood. Asexual morph: Hyphomycetous. Colonies in vivo effuse, brown to black, hairy. Setae absent. Conidiophores macronematous, mononematous, cylindrical, straight. Conidiogenous cells generally monophialidic, rarely polyphialidic with up to two lateral enteroblastic openings, collarette hyaline to subhyaline. Conidia cylindrical, tapering slightly, with rounded apex, obtuse at base, 1-septate, not constricted at septum, hyaline, guttulate, smooth. Sexual morph: Stroma absent. Ascomata superficial, solitary or aggregated, brown, venter subglobose to conical. Ostiole periphysate. Peridium fragile, 2-layered. Paraphyses filiform, septate, hyaline, forming a branching and anastomosing ‘‘network’’. Asci 8-spored, unitunicate, cylindrical-clavate, short-pedicellate. Ascospores ellipsoidal to fusiform, septate, hyaline (adapted from Luo et al. 2019).
Type species: Cylindrotrichum oligospermum (Corda) Bonord., Handb. Allgem. mykol. (Stuttgart): 88 (1851)
Notes: Cylindrotrichum 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. (2016) recommended the use of Cylindrotrichum over Reticulascus given its widespread use, priority, and greater number of names.
