A new homobasidiomycete, Asterostroma boninense, was found in the Bonin (Ogasawara) Islands, a subtropical region in Japan. This species is morphologically characterized by having resupinate basidiomata, a monomitic (asterodimitic) hyphal system, simple septate generative hyphae, dextrinoid asterosetae, four sterigmate basidia, and subglobose, tuberculate, amyloid basidiospores. It is similar to A. muscicola, but the latter has smaller basidia. In Japan, A. muscicola is widely distributed in warm-temperate to subtropical regions including the Bonin Islands, while A. boninense is restricted to the Bonin Islands. Another species in the genus, Asterostroma andinum, is also reported as new to Japan. A key to the Japanese species of Asterostroma is provided.
