Yang et al. (2016) introduced the hyphomycetous genus Mucispora, with M. obscuriseptata as the type. Mucispora is characterized by effuse, dark brown and hairy colonies. The mycelium is partly superficial and partly immersed, consisting of branched, septate, pale brown to dark brown hyphae. Macronematous mononematous conidiophores occur solitarily or in small groups on compactly aggregated cells. They are simple, erect, cylindrical, septate, brown, straight or somewhat flexuous, and smooth-walled. Some cells have percurrent proliferation. Conidiogenous cells are monoblastic, holoblastic, integrated, terminal, cylindrical, pale brown and smooth-walled. The conidia are acrogenous, solitary, simple, and ellipsoidal to obovoid with a truncate base. They are hyaline to subhyaline when young, dark brown when mature, paler at the basal cell, with obvious septa in young conidia. The conidial wall is smooth and is sometimes covered by a hyaline mucilaginous sheath. The sexual morph is undetermined. Mucispora species are saprobic on decaying plant substrates submerged in freshwater (Yang et al. 2016, 2017; Wijayawardene et al. 2021; Du et al. 2022). Mucispora accommodates five species (Yang et al. 2016, 2017; Wijayawardene et al. 2021; Du et al. 2022).
