N2 - Five yeast isolates obtained from cashew tree flowers in Nigeria resembled Cryptococcus neoformans phenotypically by producing brown pigmented colonies on niger seed agar, expressing a capsule, and being able to grow at 37°C. However, rRNA gene sequences, including the 18S rRNA gene, the D1/D2 domains of the 26S rRNA gene and the ITS1+2 regions, suggested that these yeasts form a basal lineage within the Trichosporonales (Tremellomycetidae, Hymenomycetes, Basidiomycota, Fungi). Since the isolates could not be identified with any known genus and species within the Trichosporonales, we describe them as Cryptotrichosporon anacardii gen. et sp. nov. with CBS 9551T (=NRRL Y-27671) as the type strain. The taxonomic conflict between phenetic and molecular classification schemes within this group of fungi is discussed, and is resolved in favor of the latter.
