Melanina Grube, Muggia, de Hoog, gen. nov. (Fig. 6)
MycoBank number: MB 838740; Index Fungorum number: IF 838740; Facesoffungi number: FoF 10460;
Etymology: The genus name refers to the melanized mycelium, and therefore its inclusion in the group of “melanized, black fungi.”
Type species: Melanina gunde-cimermaniae Grube, Muggia, de Hoog—MycoBank: MB838767 (Fig. 6)
Monotypic genus in the order Chaetothyriales, Ascomycota. Endolichenic fungi, for which the sexual morph is unknown. Colonies growing rather slowly in vitro, dark gray to black. Hyphae toruloid, hyaline to heavily melanized. Superficial hyaline hyphae rare; yeast-like growth in the central internal part of the colony, cell walls slightly verrucose. Conidia pale pigmented, organized in chains, likely resulting from a blastic-percurrent or arthric ontogeny.
