Plectosphaerella was introduced by Klebahn in 1929 (Palm et al. 1995). The type species is Plectosphaerella cucumerina, a holomorphic fungus (Zare et al. 2007, Carlucci et al. 2012). Plectosphaerella can be distinguished from other taxa by its asexual morph with the ratio of septate conidia, conidial shape and dimensions and presence or absence of chlamydospores (Carlucci et al. 2012)

Type species: Plectosphaerella cucumerina (Lindf.) W. Gams.

Other accepted species: Species Fungorum – search Plectosphaerella.
