Genetic relatedness among Filobasidiella species.
The three accepted species of Filobasidiella, F. neoformans, F. depauperata, and F. lutea, are compared morphologically and by molecular analysis. Sequences of the internally transcribed spacer (ITS) and the small subunit (SSU) gene of the ribosomal RNA (rRNA) gene cluster were obtained, and analysed by Neighbor-joining and Maximum parsimony methods. The three species of Filobsidiella are shown to form a single monophyletic clade, rooted by Tremella mesenterica. F. lutea was recovered as a distinct, but closely related taxon with the Filobasidiella clade. This is the first report of DNA sequences from herbarium specimens of F. lutea.
