Yeast strains belonging to the basidiomycetous genus Cryptotrichosporon were isolated from forest soils in Serra da Arrábida Natural Park in Portugal. Similar to the already-known representatives of this genus, the new isolates formed pigmented colonies of a distinctive pale orange colour. Phylogenetic analyses employing concatenated sequences of the D1/D2 domains of the 26S (large subunit) rRNA gene and the internal transcribed spacer (ITS) region supported the recognition of three novel species: Cryptotrichosporon argae sp. nov. (type strain CM 19T=CBS 14376T=PYCC 7010T=DSM 104550T; MycoBank accession number MB 817168), Cryptotrichosporon brontae sp. nov. (type strain CM 1562T=CBS 14303T=PYCC 7011T=DSM 104551T; MycoBank accession number MB 817077) and Cryptotrichosporon steropae sp. nov. (type strain OR 395T=CBS 14302T=PYCC 7012T=DSM 104552T; MycoBank accession number MB 817078).
属于担子菌纲隐丝孢酵母属的酵母菌株是从葡萄牙阿连特茹自然公园的森林土壤中分离出来的。与该属已知的代表菌株相似，新分离的菌株形成了独特的浅橙色色素菌落。利用26S（大亚基）rRNA基因的D1/D2结构域和内部转录间隔区（ITS）区域的串联序列进行的系统发育分析支持了三个新物种的认定：阿氏隐丝孢酵母（Cryptotrichosporon argae sp. nov.）（模式菌株CM 19T = CBS 14376T = PYCC 7010T = DSM 104550T；国际真菌名称索引登录号MB 817168）、布朗氏隐丝孢酵母（Cryptotrichosporon brontae sp. nov.）（模式菌株CM 1562T = CBS 14303T = PYCC 7011T = DSM 104551T；国际真菌名称索引登录号MB 817077）和斯特罗帕氏隐丝孢酵母（Cryptotrichosporon steropae sp. nov.）（模式菌株OR 395T = CBS 14302T = PYCC 7012T = DSM 104552T；国际真菌名称索引登录号MB 817078）。
