Melchioria Penz. & Sacc., Malpighia 11(9-10): 399 (1897)
Hypocreomycetidae, Hypocreales, Niessliaceae, Melchioria
Index Fungorum number: IF 3099; 6 morphological species (Species Fungorum 2020).
Saprobic or parasitic on leaves or stems. Sexual morph: Ascomata perithecial, densely gregarious, superficial, globose to subglobose, black, carbonaceous to coriaceous, glabrous, not collapsing, ostiolate, periphysate. Peridium composed of dark brown to hyaline cells of textura angularis to textura prismatica. Paraphyses absent or filiform. Asci 8-spored, unitunicate, clavate, pedicellate, apical ring indistinct, evanescent. Ascospores bi-seriate or overlapping, hyaline, fusiform, straight or slightly curved, 1-septate, smooth-walled, guttulate. Asexual morph: Undetermined (copied from Huang et al. 2021).
Type species: Melchioria leucomelaena Penz. & Sacc., Malpighia 11(9-10): 399 (1897)
Notes: Melchioria was initially considered similar to Sphaeria with black ascomata and hyaline, fusiform ascospores (Penzig & Saccardo 1897). This genus was subsequently listed in Niessliaceae (Lumbsch & Huhndorf 2007). However, Melchioria does not have setose or hairy ascomata similar to other Niessliaceae members, and there is no molecular data available for this genus. In their study, Huang et al. (2021) have maintained Melchioria in Niessliaceae pending future work (copied from Huang et al. 2021).
