Pleopunctum N.G. Liu, K.D. Hyde & J.K. Liu

Index Fungorum number: IF 556522; Facesoffungi number: FoF 06113


Saprobic on decaying wood in terrestrial or submerged wood in freshwater habitats. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies clustered in several small groups or gregarious, sporodochial, punctiform, brown to black, shining. Mycelium immersed in the substratum, composed of septate, branched, subhyaline to greyish brown hyphae. Conidiophores macronematous, mononematous, cylindrical, branched, or unbranched, septate, medium brown, smooth-walled, thick-walled. Conidiogenous cells holoblastic, monoblastic, cylindrical, brown. Conidia acrogenous, solitary, muriform, constricted at septa, broadly oval to ellipsoidal, variable in shape, smooth-walled, pale brown to dark brown, often with a hyaline, ellipsoidal to globose basal cell. (Descriptions from Dong et al. 2020)


Type species: Pleopunctum ellipsoideum N.G. Liu, K.D. Hyde & J.K. Liu


Notes: Pleopunctum was introduced to accommodate two terrestrial species, P. ellipsoideum N.G. Liu et al. and P. pseudoellipsoideum N.G. Liu et al., collected from decaying wood in China (Liu et al. 2019). Pleopunctum is characterized by muriform, oval to ellipsoidal conidia often with a hyaline, elliptical to globose basal cell (Liu et al. 2019). Pleopunctum, the only hyphomycetous genus, formed a wellsupported and distinct clade in Phaeoseptaceae (Liu et al. 2019). We collected P. pseudoellipsoideum from submerged wood in China. (Notes from Dong et al. 2020)
