The genus is characterised as 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.

Comments:

NOTES: This species was described as Cryptococcus keelungensis isolated from the surface microlayer at Keelung, north–east Taiwan (Chang et al. 2008), but in a major phylogenetic re–assessment of basidiomycete yeasts referred to Solicoccozyma (Liu et al. 2015). The species of this genus are usually obtained from soils (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 lowweight aromatic compounds, such as L–malic, L–tartaric, saccharic, mucic, caffeic, gentisic, p–coumaric, protocatechuic and hydroxybenzoic acids (Fonseca et al. 2011). This genus currently contains six described species but only S. keelungensis is known from marine habitats (Jones et al. 2015). The genus is assigned to the Piskurizynaceae a family is proposed for a strongly supported monophyletic lineage including the aerius (Solicoccozyma) and cylindricus (Piskurozyma) clades and a single species clade Filobasidium capsuligenum in Filobasidiales resolved by a seven–gene dataset analysis (Liu et al. 2015).
