Classification: Incertae sedis, Incertae sedis, Incertae sedis, Incertae sedis, Pezizomycotina, Ascomycota, Fungi
Parasitic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata brown, acervular, scattered or confluent, immersed to erumpent, depressed-globose, unilocular, glabrous. Ostiole absent, opening by irregular splits of apical host tissue. Conidiomatal wall composed of thick-walled, pale brown to hyaline cells of textura angularis. Conidiophores arising from inner layer of the basal part of condioma, hyaline, irregular, branched, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical to lageniform, integrated or determinate, smooth-walled. Conidia hyaline, cylindrical to fusiform with acute apex and slightly truncate base, straight or slightly curved, 0–1-septate, smooth-walled, eguttulate (Sutton 1980).
Notes: This description is based on Cylindrogloeum trillii (Ell. & Ev.) Arx. Sutton (1980) gave details of the taxonomy of this genus. No sexual morph has been linked to this genus and no molecular data is available.
Type species: Cylindrogloeum arcticum Petr., Annls mycol. 39(4/6): 276 (1941).
