This species has subreniform pileus with blackbrown upper surface and distinct concentric zones. Stipes are sturdy (6-9 cm long, 0.6-1 cm thick), and spores are larger (10.5-13 × 6.7-8.7 μm). This species and Ganoderma parviun gulatum Zhao et Zhang is proximal, but the latter differs in having unguliform pileus with purple brown or reddish brown upper surface and indistinct concentric zones, moreover, the stipe of the latter is thin and delicate (3.5-15 cm long, 0.3-0.7 cm thick), and the spores are smaller (8-9.7 × 4.5-6.1μm). Other 2 species, Ganoderma tropicum (Jungh.) Bres. and Humphreya coffeatum (Berk.) Steyaert are briefly discussed.All the specimens cited in this paper are deposited in the Mycological Herbarium of the Institute of Biology, Guizhou Academy of Sciences (HMBAG).
