Classification: Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi 

Fungicolous on Massaria spp. on corticated branches of Acer spp. Sexual morph: Ascomata perithecial, pale luteous to yellow-orange, aggregated in clusters, on a single stromatic base, covered in a dirty white crustose layer, turning pale luteous to dirty white, KOH-, ostiolate. Ostiole papillate, periphysate. Peridium 3–4 layers of subhyaline, smooth-walled cells of textura angularis. Asci 8-spored, unitunicate, fusoidal-ellipsoidal to subclavate, hyaline, smooth-walled. Ascospores fasciculate, hyaline, fusoidal-ellipsoidal with obtuse ends, septate, warty, not to slightly constricted at septa. Asexual morph: Conidiomata sporodochial, determinate, hyaline, becoming orange. Conidiophores subcylindrical, septate, branched. Conidiogenous cells subcylindrical, terminal and intercalary, hyaline, smooth-walled, proliferating sympodially at apex. Conidia slimy, solitary, granular to guttulate, straight to gently curved, subcylindrical to narrowly obclavate, hyaline, smooth-walled (adapted from Crous et al. 2015b).

Notes – Flammocladiellaceae was introduced to accommodate the monotypic genus Flammocladiella by Crous et al. (2015b). In the molecular analysis by Hongsanan et al. (2017) and Sun et al. (2017), Flammocladiellaceae grouped within Clavicipitaceae, hence was not treated as a separate family. Further, Hongsanan et al. (2017) synonymized Flammocladiellaceae under Clavicipitaceae based on phylogenetic data and this was followed by Wijayawardene et al. (2018a). However, in the molecular clock analysis by Hyde et al. (2017a) Flammocladiellaceae forms a separate clade sister to Clavicipitaceae with low statistical support. Similar results were obtained from phylogenetic analysis by Maharachchikumbura et al. (2016b) and Lechat & Fournier (2018). Hence, we would like to treat Flammocladiellaceae as an accepted family within Hypocreales, based on previous treatments and our phylogenetic analysis.
