Abstract
Ten yeast isolates representing four candidate novel species of the genus Teunomyces 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 Teunomyces stri, two isolates related to Teunomyces atbi, two isolates related to Teunomyces aglyptinius, and another two isolates related to Teunomyces aglyptinius, Teunomyces barrocoloradensis, Teunomyces gatunensis and Teunomyces stri. 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 Marasmiellus volvatus, Tricholomopsis aurea, Hydropus sp. and Favolus tenuiculus, or drosophilids feeding on these substrates. The names Teunomyces gombertii f.a., sp. nov. (holotype CBS 16168T; Mycobank MB849065), Teunomyces landelliae f.a., sp. nov. (holotype =CBS 16169T; Mycobank MB 849066), Teunomyces ledahaglerae f.a., sp. nov. (holotype CBS 16170T; Mycobank MB 849067) and Teunomyces paulamoraisiae f.a., sp. nov. (holotype CBS 16120T; Mycobank MB 849068) are proposed for these species.
