Clohesyomyces aquaticus

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

Facesoffungi number: FoF 07165

 

Saprobic on submerged wood in a freshwater stream. Sexual morph: undetermined. Asexual morph: Conidiomata 150–250 µm diam., 200250 µm high, dark brown to black, pycnidial, subperidermal, solitary to gregarious, semi-immersed, globose to subglobose, unilocular, thick-walled, glabrous, ostiolate. Ostiole single, papillate, circular, centrally located. Conidiomatal wall 20–40 µm wide, consisting of brown to pale brown, thick-walled cells of textura angularis gradually merging with textura porrecta. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 6–15 × 2–10 µm, hyaline, phialidic, cylindrical to subcylindrical or lageniform, determinate, thick- and smooth-walled, with marked periclinal thickening at collarette zone. Conidia 10–23 × 7–10 µm (x = 17 × 8 µm; n = 30), hyaline, ellipsoidal, rounded at both ends, or occasionally truncate at base, 1-septate, slightly constricted at septum, straight or slightly curved, thick-walled, smooth, guttulate, surrounded by an irregular mucilaginous sheath.
