Ascomycota, genera incertae sedis


Parasitic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata very pale brown, pycnidial, solitary to gregarious, immersed, globose to irregular, unilocular, glabrous. Ostiole indistinct. Conidiomatal wall composed of thick-walled, pale brown to hyaline cells of textura angularis. Conidiophores lining all around the cavity of conidiomata, reduced to conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical to lageniform, discrete, determinate, with minute apical collarette and prominent channel, with periclinal thickening around the channel. Conidia hyaline, fusiform, narrowed and obtuse at the apex, truncate at the base, 1-septate, smooth-walled (Sutton 1980).


Type species: Diplozythiella bambusina Died., in Sydow, Sydow & Butler, Annls mycol. 14(3/4): 215 (1916)


Notes: The genus remains monotypic, and there is no molecular data available. Diplozythiella bambusina is a pathogen and associated with lesions on leaves of Bambusa (Poaceae) (Sutton 1980). Diplozythiella shares similar form of conidia with Microperella. The differences between these two genera were shown under Microperella.


Distribution: India (Sutton 1980).
