Genolevuria
Genolevuria Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 113 (2015)
Etymology: The genus is named in honour of the French yeast genomics consortium “Genolevures” that produced high-quality yeast genome data.
Diagnosis: Basidiocarps not present. Colonies usually orange-coloured. Pseudohyphae occasionally present. True hyphae not observed. Budding cells present. Ballistoconidia not observed. Fermentation absent. Nitrate not utilised. Starch-like compounds weakly produced or not produced at all. Major CoQ system CoQ-10.
Index Fungorum number: IF813329
Type species: Genolevuria amylolytica (Á. Fonseca, J. Inácio & Spenc.-Mart.) Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 113 (2015)
Notes: The species of this genus have orange-coloured colonies (Inácio et al., 2005, Wang et al., 2007, Landell et al., 2009, Liu et al., 2015a), which is not a common characteristic among tremellaceous yeasts (Fonseca et al. 2011).

Figure 1. Phylogenetic relationships of yeasts and related taxa from the order Tremellales in Tremellomycetes obtained by maximum-likelihood analysis of LSU (D1/D2 domains) rRNA gene. Tree topology was backbone-constrained with the well-supported (>85 %) bipartitions of the topology of the seven-genes tree (Liu et al. 2015a). 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 and in brackets following recognised clades. The type species of accepted genera are in bold and the taxa not included in the seven-genes dataset (Liu et al. 2015a) are in red. Note: ns, not supported (BP < 50 %).
