Ascomycota, genera incertae sedis

Parasitic on Pennisetum sp. (Poaceae). Sexual morph: undetermined. Asexual morph: Conidiomata pale brown, stromatic, pycnidial, scattered, immersed or semi-immersed, elongated to subglobose, unilocular, glabrous. Ostiole absent, dehiscence by irregular splits of apical wall. Conidiomatal wall composed of thin-walled, hyaline cells of textura angularis in the base part, becoming thick-walled, with brown cells at the upper part. Conidiophores arising from inner wall layer of conidiomata, hyaline, cylindrical, branched, septate, smooth-walled. Conidiogenous cells hyaline, polyblastic, sympodial, integrated, determinate, smooth-walled, with 1–3 apical slightly protruding, conidiogenous loci without scars. Conidia hyaline, cylindrical, with obtuse apex and truncate base, unicellular, smooth-walled, eguttulate.


Type species: Hypocline penniseti Syd., Annls mycol. 37(3): 246 (1939)


Notes: Hypocline is monotypic, and is associated with lesions on Pennisetum sp. in Uganda (Sutton 1980). This genus shares similar morphology of conidiogenous cells with Rhabdogloeopsis. The differences between these genera are detailed under notes of Rhabdogloeopsis. There is no molecular data available for this genus. Fresh collections of H. penniseti are needed to place this genus in a natural group.


Distribution: Uganda (Sutton 1980).
