| Outline of Final Research Achievements |
A taxonomic revision was conducted on the fungal population that had been considered to be a single species due to morphological similarities. In order to determine the possible existence of undescribed cryptic species, the phylogenetic significance of traits that were once recognized as minute intra-species morphological variations was evaluated based on molecular phylogenetic analyses using sequences of 18S, ITS, 28S nrDNA, tef-1, rpb2, and beta-tubulin. The analysis found, for example, that the freshwater ascomycete Lophiostoma bipolare, which has been reported from various countries, was a heterogenous species-complex comprised of seven genera and eleven species. Including the above result, four new families, 17 new genera, and 50 new species (including eight new combinations) were discovered and described, demonstrating species diversity and uniqueness of fungi in Japan.
