Solicoccozyma

Solicoccozyma Xin Zhan Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 119 (2015)

Etymology: In reference to the ecological origin of the species in this genus that are mostly isolated from soils.

Diagnosis: Basidiocarps absent. Sexual reproduction with holobasidia may be present. Pseudohyphae and true hyphae occasionally produced. Clamp connections may be present on dikaryotic hyphae. Haustorial branches not observed. Budding cells present. Ballistoconidia absent. Fermentation absent. Nitrate utilised. Starch-like compounds usually not produced. The major CoQ system CoQ-10.

Index Fungorum number: IF812197

Type species: Solicoccozyma aeria (Saito) X.Z. Liu, F.Y. Bai, M. Groenew. & Boekhout, in Liu et al., Studies in Mycology 81: 119 (2015)

Notes: The aerius clade on which the new genus is based was consistently resolved and strongly supported in the trees using different datasets (Fonseca et al., 2011, Liu et al., 2015a, b). The species of this genus are usually obtained from soils (Botha, 2006, Fonseca et al., 2011, Yurkov et al., 2012). They frequently produce thick polysaccharide capsules and accumulate substantial amount of lipids (Tanimura et al. 2014). They have a pronounced ability to assimilate aldaric acids and low-weight aromatic compounds, such as l-malic, l-tartaric, saccharic, mucic, caffeic, gentisic, p-coumaric, protocatechuic and hydroxybenzoic acids (Fonseca et al. 2011).

Figure 1. Phylogenetic relationships of yeasts and related taxa from the order Filobasidiales 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 %).
