Ascomycota, genera incertae sedis


Saprobic on the host plant. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, pycnidial, scattered, superficial, globose in section view, unilocular, glabrous. Ostiole single, circular, centrally located. Conidiomatal wall composed of thick-walled, dark brown to hyaline cells of textura angularis. Conidiophores formed from the inner wall layer of conidiomata, hyaline, cylindrical, branched, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical, integrated or discrete, determinate, smooth-walled. Conidia hyaline, spherical, unicellular, smooth-walled, often with a single guttule (adapted from Sutton 1980).


Type species: Pleurophomopsis salicicola Petr., Annls mycol. 22(1/2): 156 (1924)


Notes: Sutton (1980) revised Pleurophomopsis based on P. salicina Petr. He noted that if P. salicina is not congeneric with the type P. salicicola, then this generic account needs to be modified. Seven taxa, P. eucalypti Petr., P. lignicola Petr., P. nypae K.D. Hyde & B. Sutton, P. salicicola Petr., P. salicina Petr., P. strictae S. Ahmad, and P. valentina Urries were included in Pleurophomopsis, but most of them have not been examined (Sutton 1980, Hyde and Sutton 1992). The sexual morph of Pleurophomopsis was reported in Lophiostoma Ces. & De Not. (Leuchtmann 1985, Zhang et al. 2009), but this connection has never been successfully demonstrated. Wijayawardene et al. (2017b) placed Pleurophomopsis in Ascomycota, incertae sedis, since there is a lack of molecular data. Fresh collections of generic type and other taxa are needed to redefine the generic concept.



Distribution: China, Czechoslovakia, Italy, Pakistan, Spain (Sutton 1980, Hyde and Sutton 1992, this study).
