Leotiomycetes, Leotiomycetidae, Rhytismatales, Calloriaceae


Saprobic on the host plant in terrestrial habitat. Sexual morph: see Haelewaters et al. (2018). Asexual morph: Conidiomata yellowish brown, acervular, solitary to gregarious or confluent, immersed, circular to elongated, unilocular, glabrous. Ostiole absent, dehiscence by breakdown of host tissue. Conidiomatal wall composed of thick-walled, pale brown to hyaline cells of textura angularis. Paraphyses hyaline, filiform, attenuated above, branched, septate. Conidiophores arising from the inner wall layer of basal stroma, hyaline, cylindrical, branched, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical, integrated or discrete, determinate, smooth-walled. Conidia hyaline, fusiform to almost falcate, with obtuse apex and truncate base, often anastomosing in the acervulus by germination tubes produced just above the base, 1-septate, smooth-walled, eguttulate (adapted from Sutton 1980).


Type species: Stamnaria persoonii (Moug.) Fuckel, Jb. nassau. Ver. Naturk. 23-24: 309 (1870) [1869-70]

= Titaeospora detospora (Sacc.) Bubák, Annls mycol. 14(5): 345 (1916)


Notes: Titaeospora is characterized by fusiform to falcate conidia interconnected by germination tubes produced just above the base. Titaeospora equiseti is a synonym of T. detospora (type of Titaeospora) and was considered as asexual morph of Stamnaria persoonii (type of Stamnaria) (von Arx 1970, Sutton 1980, Gruber 2006). Johnston et al. (2014) regarded them are congeneric and recommended to used older name Stamnaria. Based on the available sequence data, Stamnaria is placed in Calloriaceae (Rhytismatales, Leotiomycetes) (Ekanayaka et al. 2018). No molecular data is available for asexual morph of Stamnaria. Fresh collections are needed to confirm the connection between the two morphs.


Distribution: worldwide (Wijayawardene et al. 2017).
