Teunia Q.M. Wang & F.Y. Bai gen. nov. MycoBank MB828751.

Etymology: the genus is named in honour of Dr. Teun Boekhout for his contributions to yeast taxonomy.

This genus is proposed for the clade represented by Cryptococcus cuniculi , which clustered with Fonsecazyma tronadorensis ( Cryptococcus tronadorensis ), Fonsecazyma betulae ( Kwoniella betulae ) and three new species represented by CGMCC 2.4450, CGMCC 2.5648 and CGMCC 2.3835, respectively. Member of the Cryptococcaceae ( Tremellales ). The genus is mainly circumscribed by the phylogenetic analysis of the seven genes dataset, in which it occurred as a well supported clade within Cryptococcaceae ( Fig. 2 ).

Sexual reproduction not known. Colonies cream to yellow, butyrous to mucoid. Budding cells present. Pseudohyphae and hyphae are not produced. Ballistoconidia are not formed.

Type species: Teunia korlaensis Q.M. Wang, F.Y. Bai & A.H. Li.

Figures

Fig. 2. Phylogenetic tree inferred using the combined sequences of RPB1, RPB2, TEF1, CYTB, SSU rDNA, LSU rDNA D1/D2 domains and 5.8S rDNA, depicting the phylogenetic positions of new taxa (in bold) within Tremellomycetes (Agaricomycotina). The tree backbone was constructed using maximum likelihood analysis. Bootstrap percentages of maximum likelihood analysis over 50 % from 1 000 bootstrap replicates and posterior probabilities of Bayesian inference above 0.9 are shown respectively from left to right on the deep and major branches. Bar = 0.05 substitutions per nucleotide position. Note: ns, not supported (BP <50 % or PP <0.9); nm, not monophyletic. The new taxa are in bold.
