Abstract

Ten yeast isolates representing four candidate novel species of the genus were obtained from different species of mushrooms and drosophilids collected in an Amazonian Forest biome in Brazil. Sequence analyses of the ITS 5.8S region and the D1/D2 domains of the large subunit rRNA gene showed that four isolates were phylogenetically related to , two isolates related to , two isolates related to , and another two isolates related to , , and . The four novel species differ by 3 % or more of sequence divergence in D1/D2 domains from their closest relatives. These species were isolated from basidiocarps of the mushrooms , , sp. and , or drosophilids feeding on these substrates. The names f.a., sp. nov. (holotype CBS 16168; Mycobank MB849065), f.a., sp. nov. (holotype =CBS 16169; Mycobank MB 849066), f.a., sp. nov. (holotype CBS 16170; Mycobank MB 849067) and f.a., sp. nov. (holotype CBS 16120; Mycobank MB 849068) are proposed for these species.

摘要

从巴西亚马逊雨林生物群落中收集的不同种类的蘑菇和果蝇中获得了 10 株代表四个候选新型种的酵母分离株。ITS 5.8S 区和大亚基 rRNA 基因的 D1/D2 区序列分析表明，四个分离株与亲缘关系最近的属中的四个种聚为一支，两个分离株与亲缘关系最近的属中的两个种聚为一支，另外两个分离株与亲缘关系最近的属中的、、和三个种聚为一支。这四个新种在 D1/D2 区的序列差异大于或等于 3%，与它们最接近的亲缘种不同。这些种从蘑菇的担子果中分离出来，如、、 sp. 和，或从以这些基质为食的果蝇中分离出来。这些新种分别被命名为 f.a.，sp. nov.（模式株 CBS 16168；Mycobank MB849065）、 f.a.，sp. nov.（模式株 CBS 16169；Mycobank MB 849066）、 f.a.，sp. nov.（模式株 CBS 16170；Mycobank MB 849067）和 f.a.，sp. nov.（模式株 CBS 16120；Mycobank MB 849068）。
