Ganoderma tropicum (Jungh.) Bres., Ann. Mycol. 8: 586. 1910.
Description：
Basidiocarp annual, stipitate, corky to woody. Pileus dimidiate, subflabelliform, subreniform or subinfundibuliform, 2.5-8.5 × 4.5-15 × 0.5-2 cm; upper surface reddish brown, purplish red to purplish brown, slightly laccate. Context uniformly brown, 0.5-1.9 cm thick. Tubes 0.1-0.2 cm long, brown. Pore surface sordid white or brownish, sometimes faintly brown; pores irregular, 4-5 per mm. Stipe lateral or eccentric, sometimes sessile, rather strongly laccate. Pilear crust a hymenioderm, brownish to brown; hyphal elements clavate, 20-25 µm long, at inflated part usually 4-6 µm wide, covered with glutinous substance at apex of some hyphae. Hyphal system trimitic; generative hyphae hyaline, thin-walled, 3-5 µm diam; skeletal hyphae brownish, thick-walled to solid; binding hyphae colorless, thick-walled, 1-2.5 µm diam. Basidiospores 8.5-11.5 × 5.0-7.0 µm, ovoid, subellipsoid or at apex slightly truncate, bituni-cate; exospore hyaline, smooth, endospore brownish, sometimes guttulate, echinulate.
