Pleopunctum
Pleopunctum N.G. Liu, K.D. Hyde & J.K. Liu, Mycosphere 10 (1): 767 (2019).
Index Fungorum number: IF 556522; Facesoffungi number: FoF 06113; 3 morphological species (Species Fungorum, 2022), 3 species with molecular data.
Saprobic on decaying wood in terrestrial habitats. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies on natural substrate sporodochial, superficial, brown, scattered, gregarious, punctiform. Mycelium immersed in the substratum, composed of septate, branched, subhyaline to greyish brown hyphae. Conidiophores macronematous, mononematous, cylindrical, branched, septate, medium brown, smooth-walled, thick-walled. Conidiogenous cells monoblastic, cylindrical, brown. Conidia acrogenous, solitary, muriform, constricted at septa, broadly oval to ellipsoidal, smooth-walled, pale brown when immature, broadly obtuse at apex and dark brown, truncate at base and paler brown when mature, often with a hyaline, elliptical to globose basal cell (Adapted from Liu et al., 2019).
Type species: Pleopunctum ellipsoideum N.G. Liu, K.D. Hyde & J.K. Liu
Notes: Liu et al. (2019) introduced Pleopunctum to accommodate two saprobic species P. ellipsoideum and P. pseudoellipsoideum from China. Phukhamsakda et al. (2020) described the third species P. clematidis Phukhams., Bhat & K.D. Hyde on dried stem of Clematis sikkimensis from Thailand. Pleopunctum clematidis is distinguishable in this genus by its dimorphic conidia. The sexual morph of Pleopunctum has not been determined. Molecular markers available for Pleopunctum include LSU, SSU, ITS, TEF-1 and RPB2.
