Index Fungorum number: IF814775

Type species: Bandonia marina (Uden & Zobell) Yurkov, Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 113 (2015)

Notes: The phylogenetic position of Cryptococcus marinus in Tremellomycetes remained unclear (e.g., Fonseca et al. 2011) before the seven-genes phylogenetic analysis (Liu et al. 2015a). The latter analysis placed the species in Trichosporonales with some affinity to the genera Cryptotrichosporon and Takashimella. The species is known from a single strain only and is characterised by several unusual physiological properties (Fonseca et al. 2011).

Figure 1. Phylogenetic relationships of yeasts and related taxa from the orders Trichosporonales 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 %).
