Facesoffungi number: FoF 00756

Dothideomycetes, Pleosporomycetidae, Pleosporales, Melanommataceae


Saprobic on the host plant in terrestrial habitat. Sexual morph: see Tibpromma et al. (2017). Asexual morph: Conidiomata black, stromatic, pycnidial, solitary to gregarious or confluent, immersed to semi-immersed to superficial, globose to subglobose, unilocular or multilocular, glabrous, ostiolate. Ostiole circular, centrally located. Conidiomatal wall composed of thick-walled, dark brown to hyaline cells of textura angularis. Conidiophores arising from the inner cavity of the conidiomata, hyaline, cylindrical, branched at the base, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical, integrated or discrete, determinate, smooth-walled, with terminal or lateral apertures. Conidia hyaline, cylindrical to ellipsoidal, unicellular, smooth, guttulate (Sutton 1980).


Type speciesAposphaeria pulviscula (Sacc.) Sacc., Michelia 2(6): 4 (1880)


Notes: Sutton (1980) and Tian et al. (2015) redescribed and illustrated the generic type of Aposphaeria. More than 200 taxa are included in Aposphaeria, but most of them have not been re-studied (Sutton 1980). De Gruyter et al. (2013) showed that Aposphaeria was phylogenetically related to Melanommataceae, and Tian et al. (2015) accepted Aposphaeria as a separate genus in this family. Hashimoto et al. (2017) re-circumscribed Melanommataceae and accepted Melanomma Nitschke ex Fuckel sensu stricto in the family; Aposphaeria and other genera accepted by Tian et al. (2015) however, were placed in Pleosporales incertae sedis. However, Wanasinghe et al. (2018) adopted a broad concept as did Tian et al. (2015) and included Aposphaeria in Melanommataceae. A fresh collection (MFLU 16-2412) from Russia shares similar mophology and phylogeny with A. corallinolutea, and is thus an additional collection. We accept Aposphaeria as a member of Melanommataceae, at least until an eptype of A. pulviscula is designated. We provide a detailed description and plate for A. corallinolutea.
