Goffeauzyma
Goffeauzyma Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 119 (2015)
Etymology: The genus is named in honour of the yeast biologist and geneticist André Goffeau, who was the initiator and coordinator of the genome sequence project of Saccharomyces cerevisiae.
Diagnosis: Basidiocarps absent. True hyphae and pseudohyphae not observed. Sexual reproduction not observed. Budding cells present. Ballistoconidia absent. Fermentation absent. Lowweight aromatic compounds often not utilised. Nitrate usually not utilised. Major CoQ system CoQ-9.
Index Fungorum number: IF813251
Type species: Goffeauzyma gastrica (Reiersöl & di Menna) Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 119
Notes: The gastricus clade recognised in Liu et al. (2015a) consists of C. gastricus and C. gilvescens isolated from soil (Fell et al., 2000, Boekhout et al., 2011a, Fonseca et al., 2011); C. aciditolerans, C. ibericus and C. metallitolerans in the ARD ecoclade that were obtained from acid rock drainage (Gadanho & Sampaio 2009); and C. agrionensis from acidic water of a volcanic environment (Russo et al. 2010). Though the species of the ARD ecoclade clustered together, they did not form a significantly supported clade in the seven-genes tree (Liu et al. 2015a) and in the LSU rRNA gene tree. The PRBO test indicated that the six species of the gastricus clade did not show significant deviation compared to the species in the reference clades. Thus, they were assigned to a single genus.

Figure 1. Phylogenetic relationships of yeasts and related taxa from the order Filobasidiales 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 %).
