Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Parasitic on leaves. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Mycelium hyaline, septate, branched hyphae. Conidiophores mononematous, macronematous, hyaline, straight to flexuous. Conidiogenous cells terminal, hyaline, subcylindrical, with minute flared collarette at apex. Conidia solitary, oblong, aseptate, hyaline, smooth-walled, guttulate (adapted from Crous et al. 2017).
Notes – The hyphomycetous genus Myrtacremonium was accepted in Niessliaceae based on phylogenetic result (Crous et al. 2017). In this study, Myrtacremonium nests in Niessliaceae (70%ML/0.99BY).
Type species: Myrtacremonium eucalypti Crous, in Crous et al., Persoonia 38: 259 (2017)
