Meniscomyces Q.M. Wang & F.Y. Bai gen. nov. MycoBank MB828815.

Etymology: the genus is named after the lunately shaped vegetative cells.

This genus is proposed for the branch represented by strain CGMCC 2.5818 T, which formed a separate clade. Member of the Spiculogloeomycetes. The genus is mainly circumscribed by the phylogenetic analysis of the seven genes dataset, in which it occurred as a separate branch within the Spiculogloeomycetes ( Fig. 4A ).

Sexual reproduction not known. Colonies cream, butyrous. Budding cells present. Cells special, lunate, allantoid and falcate, which differs from the cell morphology of other taxa in Spiculogloeomycetes (Pucciniomycotina). Pseudohyphae and hyphae not produced. Ballistoconidia not formed.

Type species: Meniscomyces layueensis Q.M. Wang, F.Y. Bai & A.H. Li.

Figures

Fig. 4. 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 Pucciniomycotina. 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 = 0.2 substitutions per nucleotide position. Note: ns, not supported (BP <50 % or PP <0.9); nm, not monophyletic. The new taxa are in bold.
