Auricularia specimens deposited in the National Museum of Nature and Science, Japan, were observed to reexamine their species identification based on updated taxonomic criteria, and to verify the taxonomy and distribution of Auricularia spp. in Japan. Four of the ten specimens previously identified as A. auriculajudae were reidentified as A. americana (1), A. cornea (1), and A. villosula (2) based on morphological criteria such as medullae, abhymenial hairs, and basidiospores. The remaining six specimens could not be identified at the species level due to the lack of distinguishing morphological characteristics. Two of the five specimens previously considered A. minor were identified as different species due to basidiospore size discrepancy, but the remaining two specimens and the type specimen were in poor condition, and their basidiospores could not be properly observed. Three of the nine specimens previously identified as A. polytricha were reidentified as A. cornea based on morphological criteria. The remaining six specimens were not identified as A. polytricha. The type specimens of A. polytricha f. leucochroma and A. polytricha f. tenuis were in poor condition, and their basidiospores could not be properly observed. Reexaminations of existing specimens based on recent taxonomic criteria will contribute to updating the taxonomy and distribution of Auricularia spp. in Japan.
