Sordariomycetes, genera incertae sedis


Saprobic or parasitic on the host plant in terrestrial habitatat. Sexual morph: see Sutton (1980). Asexual morph: Conidiomata dark brown to black, acervular, solitary to gregarious or confluent, semi-immersed, flattened, circular to irregular, unilocular, glabrous. Ostiole absent, opening by longitudinal fissure in apex. Conidiomatal wall composed of thick-walled, dark brown to brown cells of textura prismatica to textura globosa. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, annellidic, cylindrical to lageniform, integrated or discrete, indeterminate, smooth-walled. Conidia hyaline, oblong to fusiform, with a narrow truncate base, unicellular, smooth-walled, guttulate (Morgan-Jones 1977).


Type species: Cryptomycella pteridis (Kalchbr.) Höhn., Mitt. bot. Inst. tech. Hochsch. Wien 2(3): 48 (1925)


Notes: Conidiogenous cells of C. pteridis were described as phailidic by Sutton (1980), while Nag Raj and DiCosmo (1981)described them as annellidic. Because type material is not available, we cannot verify which is correct. The illustration and description are mainly based on Nag Raj and DiCosmo (1981). Cryptomycella pteridis was linked to sexual morph Cryptomycina pteridis (Rebent.) Höhn., a fungus causing a leaf roll disease on bracken fern, Pteridium aquilinum (Dennstaedtiaceae) (Weymeyer 1966, Sutton 1980, Gabel 1993). Hyde et al. (2020) placed Cryptomycella in Sordariomycetes, genera incertae sedis. Three taxa are included in this genus, C. maxima Höhn., C. plumeriae Bat. & Peres and C. pteridis, but none of them has molecular data.
