A novel yeast strain, CBS 10258T, was isolated from the atmosphere in central South Africa. Sequence analysis of the D1/D2 domain and internal transcribed spacer region of the novel strain indicates that it represents a novel species within the Cryptococcus laurentii complex. Phylogenetic analyses based on the D1/D2 domain revealed that the novel strain occupies a relatively isolated position within this complex with Papiliotrema bandonii, Cryptococcus perniciosus, Cryptococcus nemorosus and Cryptococcus sp. CBS 8363 being the closest relatives. However, the novel strain could be distinguished from related species by standard physiological tests including the inability to assimilate rhamnose, methyl {alpha}-D-glucoside, salicin, lactose, erythritol, ribitol, xylitol, citrate and ethanol. In addition, no extracellular starch production was observed and the isolate was able to grow in the absence of additional vitamins. On the basis of these results, we suggest that the new strain represents a novel species for which the name Cryptococcus anemochoreius sp. nov. is proposed [type strain CBS 10258T (=NRRL Y-27920T)].

The GenBank/EMBL/DDBJ accession number for the 26S rDNA D1/D2 and internal transcribed spacer region sequences of strain CBS 10258T are DQ384929 and DQ830986, respectively.

An additional phylogenetic tree based on the sequences of the internal transcribed spacer region of strain CBS 10258T and related species is available as a supplementary figure in IJSEM Online.
