Five yeast strains were isolated from soil and sediments collected from Alps and Apennines glaciers during sampling campaigns carried out in summer 2007 and 2017, respectively. Based on morphological and physiological tests and on phylogenetic analyses reconstructed with ITS and D1/D2 sequences, the five strains were considered to belong to two related but hitherto unknown species within the genus , in an intermediate position between and . The names (holotype DBVPG 10734) and (holotype DBVPG 10736) are proposed for the two novel species and a detailed description of their morphological, physiological and phylogenetic features are presented. Both species fermented glucose, sucrose and trehalose, which is an uncommon feature in basidiomycetous yeasts, and showed septate hyphae with teliospore formation.
从 2007 年和 2017 年夏季采集的阿尔卑斯山和亚平宁山冰川的土壤和沉积物中分离出了 5 株酵母菌株。基于形态学和生理学测试以及 ITS 和 D1/D2 序列重建的系统发育分析,这 5 株菌株被认为属于属内两个相关但迄今未知的种,处于 和 之间的中间位置。这两个新种被命名为 (模式种 DBVPG 10734)和 (模式种 DBVPG 10736),并详细描述了它们的形态、生理和系统发育特征。这两个种都能发酵葡萄糖、蔗糖和海藻糖,这在担子菌酵母中是不常见的特征,并且具有隔膜菌丝和厚垣孢子形成。
