Ascomycota, genera incertae sedis

 

Saprobic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, acervular, solitary, immersed, slightly pulvinate in the centre, elongated, unilocular, glabrous. Ostiole absent, dehiscence by irregular fissure of the bark. Conidiomatal wall composed of thick-walled, brown cells of textura intricata. Conidiophores arising from the inner layer of basal wall of the conidiomata, hyaline, branched, septate, smooth-walled, with conidia formed at the apices of main and lateral branches. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical to lageniform, integrated or discrete, determinate, smooth-walled, with a minute apical channel and collarette. Conidia hyaline, cylindrical with an obtuse apex and acute base, straight or slightly curved, unicellular, smooth-walled, eguttulate (Sutton 1980).

 

Type species: Cytogloeum tiliae Petr., Annls mycol. 23(1/2): 77 (1925)

 

Notes: Cytogloeum tiliae was collected from twigs of Tilia sp. (Malvaceae) in Germany. The genus remains monotypic, and no molecular data is available. Fresh collections of type species are needed to fix the generic concept of Cytogloeum.

 

Distribution: Czechia, Germany, Sweden (Sutton 1980, https://www.gbif.org/).
