摘要

A new homobasidiomycete, Asterostroma macrosporum, was found in mangrove forests of Iriomote Island, 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 globose, tuberculate and amyloid basidiospores measuring 8.5-11 x 7.5-9 mu m. It is similar to A. muscicola, but basidiospores in the latter are smaller (7-8 x 5.5-7 mu m). Furthermore, phylogenetic analysis using internal transcribed spacer (ITS) region revealed that A. macrosporum is distinctly separated from A. muscicola. In Japan, A. muscicola is widely distributed in warm-temperate to subtropical regions, growing on a variety of broadleaved trees including mangroves, while A. macrosporum has been found only on mangroves.
