Flammocladiella Crous, L. Lombard & R.K. Schumach., Sydowia 67: 103 (2015)
MycoBank number: MB 812530; Index Fungorum number: IF 812530; Facesoffungi number: FoF 09183; 2 morphological species (Species Fungorum 2020), 1 species with sequence data.
Type species – Flammocladiella decora (Wallr.) Lechat & J. Fourn.
Notes – Flammocladiella was introduced by Crous et al. (2015b) based on a single species F. aceris. Lechat & Fournier (2018b) proposed Flammocladiella decora to accommodate Nectria decora. Flammocladiella decora produces long, subcylindrical conidia and a sexual morph, which are indistinguishable from F. aceris (Lechat & Fournier 2018b). Considering morphological similarities and phylogenetic analyses Lechat & Fournier (2018b) regarded F. aceris as a synonym of F. decora. The genus is characterised by yellowish ascomata seated on ascomata of Massaria species, aggregate in clusters, covered by a crustose layer, having a papillate, periphysate ostiolar region, and a sporodochial asexual morph forming flame-like conidial masses, conidia subcylindrical (Crous et al. 2015b, Lechat & Fournier 2018b).
