Sarcophoma Höhn.
Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1
Classification: Dothioraceae, Dothideales, Dothideomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on the host plant. Sexual morph: undetermined. Asexual morph: Conidiomata yellowish brown to dark brown, stromatic, solitary, immersed, globose to subglobose, unilocular, glabrous. Ostiole absent, dehiscence by irregular split of the apical wall. Conidiomatal wall composed of thick-walled, pale brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, mono- or polyphialidic, ampulliform to doliiform, integrated or discrete, determinate, smooth-walled, periclinal wall thickened towards apex. Conidia hyaline, ellipsoid to obpyriform, with obtuse apex and narrow and truncate base, unicellular, smooth-walled, eguttulate (adapted from Sutton 1980).
Notes: Morgan-Jones (1971), Sutton (1980) and Sivanesan (1984) considered S. miribelii (Fr.) Höhn. as the generic type and listed S. endogenospora as a synonym. Wijayawardene et al. (2017b) reinstated S. endogenospora as the generic type as it has priority. Three taxa were accepted in Sarcophoma, S. endogenospora, S. eriogoni (Ellis & Everh.) Arx and S. garganica (Sacc. & D. Sacc.) Arx (Sutton 1980, Wijayawardene et al. (2017b). Sarcophoma endogenospora (= S. miribelii) has been linked to the sexual morph Guignardia miribelii Aa based on culture study (Van der Aa 1975). However, G. miribelii was synonymized under Discosphaerina miribelii (Aa) Sivan. (Hyponectriaceae, Xylariales) by Sivanesan (1984). Due to a lack of culture and molecular data of the type species, the placement of Sarcophoma and its sexual morph are uncertain. Fresh collections are needed to place it in a natural group.
Type species: Sarcophoma endogenospora Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 125(1-2): 76 (1916).
Other accepted species: Species Fungorum – search Sarcophoma.
