MycoBank number: MB 5190; Index Fungorum number: IF 5190; Facesoffungi number: FoF 07875; – 2 morphological species (Species Fungorum 2020), molecular data unavailable.
Type species: Stegasphaeria pavonina Syd. & P. Syd., Annls mycol. 14(5): 362 (1916).
Notes: Stegasphaeria is pathogenic forming very rough round spots on leaves, consisting of many individual ascomata arranged in narrow rings. The mature ascospore are released through breakdown of the upper part of ascomata as in Mesniera; this is the main character that places them in Mesnieraceae.
