Yang et al. (2016) introduced the hyphomycetous genus Fuscosporella, with F. pyriformis as the type, based on the LSU-SSU-rpb2 phylogeny. The genus is characterized by scattered black sporodochial colonies on natural substrates. The mycelium is partly immersed and partly superficial, composed of septate hyaline hyphae. Macronematous and mononematous conidiophores are hyaline or colourless, branched and smooth-walled. Conidiogenous cells are monoblastic, holoblastic, integrated, terminal, globose, subglobose, ellipsoidal, clavate, and hyaline. Conidia are acrogenous, obovate to obpyriform, with a septum near the base, brown to dark brown and smooth-walled. The basal cells are trapeziform, triangular, and pale brown (Yang et al. 2016). The sexual morph is undetermined. Fuscosporella species are saprobic on decaying woods in freshwater habitats (Yang et al. 2016, 2023; Du et al. 2022; Xu et al. 2022). The genus accommodates five species (Yang et al. 2016, 2023; Du et al. 2022; Xu et al. 2022). Fuscosporella resembles Parafuscosporella in sporodochial conidiomata and conidial morphology (Yang et al. 2023). However, Parafuscosporella species possess a jelly like cover of conidiomata, which is not present in Fuscosporella (Boonyuen et al. 2021; Yang et al. 2020, 2023).
