Saprobic on various plants. Sexual morph: Undetermined. Asexual morph: Conidiomata sporodochial, pulvinate, often confluent, dark brown to black. Conidiophores arising from stromatic cells, simple, septate, hyaline to pale brown. Conidiogenous cells monoblastic, cylindrical to oblong, terminal, determinate, hyaline to pale brown. Conidia solitary, acrogenous, branched, cheiroid, with dark brown to black cap cells firmly united together, multi-armed; basal cells brown, cuneiform, smooth, thin-walled; arms developed downward from the cap cells, cylindrical, multi- septate, branched at base, pale brown, smooth (Schoknecht & Crane 1977, Hashimoto et al. 2016, 2017b).

TypeCryptocoryneum Fuckel.

Notes – Species in Cryptocoryneum showed a close relationship with Lophiotremataceae (Hashimoto et al. 2016). Hashimoto et al. (2017b) introduced a new family Cryptocoryneaceae to accommodate Cryptocoryneum lineage that is phylogenetically distinct from Lophiotremataceae.
