Saprobic on decaying wood in freshwater and terrestrial habitats. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Conidiomata on natural substrate sporodochial, punctiform, dark brown. Mycelium immersed, consisting of branched, septate, subhyaline to pale brown hyphae. Conidiophores micronematous or semi-macronematous, septate, hyaline to pale brown, smooth. Conidiogenous cells holoblastic, integrated, terminal, determinate, doliiform to cylindrical. Conidia acrogenous, solitary, dry, cheiroid, pale brown, complanate or non-complanate, euseptate or distoseptate, smooth-walled (Boonmee et al. 2016).

Notes: Dictyocheirospora was introduced for the species producing dark sporodochial colonies with aeroaquatic cheiroid dictyospores (Boonmee et al. 2016). Many new species and combinations were reported in the genus (Yang et al. 2018), and 21 species are listed in Index Fungorum (2020). Nine of them are from freshwater habitats, mostly in China and Thailand 

 

Type species: Dictyocheirospora rotunda M.J. D’souza, Bhat & K.D. Hyde

Other accepted species: Species Fungorum – search Cattanea.
