Haglerozyma 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 Allen N. Hagler for his work on yeast ecology and physiology.

Diagnosis: Basidiocarps not known. Sexual reproduction not observed. True hyphae sometimes disarticulate into arthroconidia. Pseudohyphae abundant or not. Budding cells present. Fermentation absent. Nitrate and nitrite not utilised. The major CoQ system unknown.

Index Fungorum number: IF813406

Type species: Haglerozyma chiarellii (Pagnocca, Legaspe, A. Rodrigues & Ruivo) Yurkov, Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 113 (2015)

Notes: Trichosporon chiarellii was branching earlier than the genus Cutaneotrichosporon in the seven-genes tree with strong posterior probability support from Bayesian analysis but without bootstrap support from ML and NJ analyses (Liu et al. 2015a). In the expanded LSU rRNA gene analysis, T. chiarellii was located in the same position without statistical support (Figure 1), suggesting the species represents a distinct lineage.


Figure 1. Phylogenetic relationships of yeasts and related taxa in Tremellomycetes (major lineages) 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. Note: ns, not supported (BP < 50 %).
