Saprobic on wood or bark in terrestrial and freshwater habitats. Sexual morph: Stromata if present minute. Ascomata perithecial, superficial, gregarious to solitary, brown to black, subglobose to conical, base flattened, slightly verruculose, glabrous with minute papilla, ostiole periphysate. Peridium 2-layered, fragile, the whole wall heavily sclerotized in the upper part, poorly developed towards the rim, absent at the base. Paraphyses numerous, filiform, sparsely septate, hyaline. Asci 8-spored, unitunicate, cylindrical to clavate, short-pedicellate, apex truncate to broadly rounded, with J-, apical ring. Ascospores uni to bi-seriate, hyaline or dark brown, ellipsoidal to fusiform, septate, mostly 2-celled, with a delayed formation of the 2 additional septa, smooth-walled, with or without end pores. Asexual morphs: Setae straight, cylindrical, septate, dark brown, paler towards the apex when present. Conidiophores macronematous, mononematous, solitary, erect, straight, sometimes curved, branched or unbranched, thick-walled, brown to dark brown, becoming paler towards the apex, terminating in a cylindrical to slightly flask-shaped or funnel-shaped, smooth-walled. Conidiogenous cells mono- or polyphialidic, collarette hyaline to subhyaline. Conidia hyaline to brown, pyriform to cylindrical, 1- or multi-septate, distal end bluntly rounded, basal end truncate, smooth-walled (adapted from Réblová et al. 2011).

Notes: Reticulascaceae was introduced by Réblová et al. (2011) in Glomerellales based on analysis of combined ITS, LSU, SSU and rpb2 sequence data. Three genera were included, i.e. Cylindrotrichum (as Reticulascus), Kylindria and Sporoschismopsis. Presently, Blastophorum is also accepted in Reticulascaceae by Hyde et al. (2016b) based on the phylogenetic analysis and morphology. In addition, Hongsanan et al. (2017) provided further evidence for the placement of Reticulascaceae in Glomerellales by showing good support in both phylogenetic and MCC trees.

Type genus: Cylindrotrichum Bonord.
