Several independent surveys of yeasts associated with different plant materials and soil led to the proposal of a novel yeast species belonging to the Tremellales clade (Agaricomycotina, Basidiomycota). Analysis of the sequences of the D1/D2 domains and internal transcribed spacer region of the large subunit of the rRNA gene suggested affinity to a phylogenetic lineage that includes Hannaella coprosmaensis, Hannaella oryzae and Hannaella sinensis. Thirty-two isolates were obtained from different sources, including bromeliads, nectar of Heliconia psittacorum (Heliconiaceae), flowers of Pimenta dioica (Myrtaceae), roots and leaves of sugar cane (Saccharum spp.) in Brazil, leaves of Cratoxylum maingayi, Arundinaria pusilla and Vitis vinifera in Thailand, soil samples in Taiwan, and prairie soil in the USA. Sequence analysis of the D1/D2 domains of the large subunit of the rRNA gene showed that the novel species differs from Hannaella coprosmaensis and Hannaella oryzae by 36 and 46 nt substitutions, respectively. A novel species is suggested to accommodate these isolates, for which the name Hannaella pagnoccae sp. nov. is proposed. The type strain is BI118(T) ( = CBS 11142(T) = ATCC MYA-4530(T)).
对与不同植物材料和土壤相关的酵母进行了几次独立调查，导致提出了一种属于 Tremellales 进化枝（担子菌纲，Basidiomycota）的新型酵母物种。对大亚基 rRNA 基因的 D1/D2 结构域和内部转录间隔区序列的分析表明，它与包括 Hannaella coprosmaensis、Hannaella oryzae 和 Hannaella sinensis 在内的系统发育谱系具有亲和力。从不同来源获得了 32 个分离株，包括凤梨科植物、Heliconia psittacorum（Heliconiaceae）花蜜、桃金娘科植物 Pimenta dioica 的花、巴西甘蔗的根和叶（Saccharum spp.）、泰国的 Cratoxylum maingayi、Arundinaria pusilla 和 Vitis vinifera 的叶、台湾的土壤样本以及美国的草原土壤。大亚基 rRNA 基因的 D1/D2 结构域序列分析表明，该新型物种与 Hannaella coprosmaensis 和 Hannaella oryzae 分别有 36 和 46 个核苷酸取代的差异。建议为这些分离株建立一个新物种，命名为 Hannaella pagnoccae sp. nov.。其模式株为 BI118(T)（=CBS 11142(T) = ATCC MYA-4530(T)）。
