Trimorphomycetaceae Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 113 (2015)

Etymology: In reference to the name of the type genus Trimorphomyces.

Diagnosis: Basidiocarps minute, pustulate up to 2 mm diameter, watery-gelatinous, milky to faintly greenish. H-shaped dikaryotic conidia form dikaryotic hyphae with clamp connections and haustorial branches. Alternatively, these conidia germinate with paired blastogenous conidia. Basidia tremella-like, narrowly clavate, pyriform to stalked capitate, and four-celled. Basidiospores bud or form ballistoconidia. In culture, true hyphae may form extensively. Budding cells present, with polar or multilateral budding. Ballistoconidia occasionally present. Fermentation absent. Nitrate not utilised. Major CoQ system CoQ-10

Index Fungorum number: IF813363

Type genus: Trimorphomyces Bandoni & Oberw., in Oberwinkler & Bandoni, Systematic and Applied Microbiology. 4:105-113

Figure 1. A taxonomic framework of genera and higher levels in Tremellomycetes based on the seven-genes phylogeny (Liu et al. 2015). The tree backbone was constructed using Bayesian analysis and branch lengths were scaled in terms of expected numbers of nucleotide substitutions per site. The Bayesian posterior probabilities (PP) and bootstrap percentages (BP) of maximum likelihood and neighbour-joining analyses from 1 000 replicates are shown respectively from left to right on the deep and major branches resolved. Note: ns, not supported (PP < 0.9 or BP < 50 %); nm, not monophyletic.
