Yunzhangomyces
Yunzhangomyces Q.M. Wang, E. Tanaka, M. Groenew., and D. Begerow in Li, Wang et al., Frontiers in Microbiology 12(no. 777338): 24 (2022)
Etymology: the genus is named in honor of Yun-Zhang Wang for his pioneering work on the taxonomy of smuts.
Diagnosis: This genus is proposed for the branch represented by Dicellomyces scirpi, which formed a separate branch from the genera in the Brachybasidiaceae family (Exobasidiales, Exobasidiomycetes). The genus is mainly circumscribed by the description of Dicellomyces scirpi and the phylogenetic analysis of the six-genes sequences.
This genus includes sexual and asexual species. Sexual member infecting Scirpus sylvaticus (Cyperaceae); basidia developing in gelatinous basidiocarps breaking through epidermis, swollen, not persistent probasidia, with paraphyses, sterigmata 2; producing allantoid or coiled conidia (Parmasto, 1968; Reid, 1976; Ingold, 1985; Piepenbring et al., 2020). Asexual species present butyrous, yellow or brown colonies, smooth or eroded margin with budding cells present.

Figure1. Phylogenetic tree inferred using the combined sequences of SSU rDNA, LSU rDNA D1/D2 domains, Internal Transcribed Spacer (ITS; including 5.8S rDNA), RPB1, RPB2, and TEF1, depicting the phylogenetic positions of new taxa (in bold) within Ustilaginomycotina. 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 = 0.1 substitutions per nucleotide position. ns, not supported (BP < 50% or PP < 0.9); nm, not monophyletic; the compressed genera are monophyletic.
