Facesoffungi number: FoF 07164

Dothideomycetes, Pleosporomycetidae, Pleosporales, Lindgomycetaceae

 

Saprobic on submerged wood in a freshwater stream. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown to black, pycnidial, subperidermal, solitary to gregarious, semi-immersed, globose to subglobose, unilocular, glabrous, ostiolate. Ostiole single, papillate, circular, centrally located. Conidiomatal wall composed of brown to pale brown, thick-walled cells of textura angularis to textura porrecta. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, phialidic, with a collarette, cylindrical to subcylindrical or lageniform, determinate, thick- and smooth-walled. Conidia hyaline, ellipsoidal, rounded at both ends, or occasionally truncate at base, 1-septate, slightly constricted at septum, straight or slightly curved, thick- and smooth-walled, guttulate, surrounded by an irregular mucilaginous sheath.

 

Type species: Clohesyomyces aquaticus K.D. Hyde, Aust. Syst. Bot. 6(2): 170 (1993)

 

Notes: Clohesyomyces aquaticus was originally reported from Australia on submerged wood in a freshwater stream (Hyde 1993). This species has been also reported in Yunnan, China and Thailand (Cai et al. 2006, Vijaykrishna et al. 2006). Zhang et al. (2012) showed that C. aquaticus was closely related to Lindgomycetaceae (Pleosporales) based on sequence data of LSU and SSU. Clohesyomyces has remained monotypic.

 

Distribution: Australia, Denmark, France, Germany, Greece, Thailand, UK, (Hyde 1993, Zhang et al. 2012, https://www.gbif.org/).
