Ascomycota, genera incertae sedis

 

Saprobic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, pycnidial, solitary to gregarious, superficial, globose to collabent, unilocular, glabrous. Ostiole single, circular, papillate, centrally located. Conidiomatal wall composed of thick-walled, dark brown cells of textura angularis in the periphery, becoming thin-walled, paler and then hyaline, small cells toward hymenium. Conidiophores formed from the inner wall of conidiomata, hyaline, cylindrical, flexuous, branched at the base, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical or ampulliform, integrated or discrete, determinate, smooth-walled, with terminal or lateral apertures and formed immediately below transverse septa, periclinal thickening at the collarette zone. Conidia hyaline, ellipsoid to cylindrical, with rounded apex and slightly truncate base, straight or curved, unicellular, smooth-walled, guttulate (Sutton 1980).

 

Type species: Dendrodomus annulatus Bubák, Bot. Közl. 14(3-4): (63) (1915)

 

Notes: Dendrodomus remains monotypic, and the type species is associated with Scrophularia bosniaca (Scrophulariaceae) (Sutton 1980). No molecular data is available for this genus. Dendrodomus shares similar morphology with Sirophoma. The differences between these two genera are discussed under Sirophoma.

 

Distribution: Yugoslavia (Sutton 1980).
