Ascomycota, genera incertae sedis


Saprobic or parasitic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, acervular, scattered to gregarious, semi-immersed, unilocular, glabrous. Ostiole absent. Conidiomatal wall composed of thick-walled, dark brown to pale brown cells of textura angularis to textura epidermoidea. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, phialidic, lageniform to cylindrical, determinate, smooth-walled, with a minute apical channel. Conidia hyaline, fusiform, straight or slightly curved, 0–3-septate, smooth-walled, eguttulate (Sutton 1980).


Type species: Cheilaria agrostidis Lib., Pl. crypt. Arduenna, fasc. (Liège) 1: no. 63 (1830)


Notes: Cheilaria resembles Myriellina, and the differences between these two genera see notes of Myriellina. Wijayawardene et al. (2017b) accepted only Cheilaria agrostidis in the genus. This species is associated with leaf lesions on Calamagrostis inexpansa, C. varia, Cymbopogon giganteus, Milium effusum (Poaceae) (Sutton 1980). No molecular data is available for this genus. Fresh collections are needed to place it in a natural group.


Distribution: Germany, Sudan, Switzerland, UK, USA (Sutton 1980).
