Abstract
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 × 7.5–9 μm. It is similar to A. muscicola, but basidiospores in the latter are smaller (7–8 × 5.5–7 μm). 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.
