MycoBank number: MB 3059; Index Fungorum number: IF 3059; Facesoffungi number: FoF 09978; 19 morphological species (Species Fungorum 2020), 16 species with sequence data.

Type speciesMelanconiella spodiaea (Tul.) Sacc.

NotesMelanconiella is restricted to recently dead corticated branches. The genus is host- specific to the plant family Betulaceae as saprobes (Senanayake et al. 2018). Voglmayr et al. (2012) revised Melanconiella using herbarium material and recently collected specimens. The dissimilarities in morphology and phylogeny of Melanconiella and Melanconis were discussed by Voglmayr et al. (2012). See Crous et al. (2016b) and Senanayake et al. (2018) for further details. Melanconiella spodiaea is illustrated in this entry.
