Ganoderma fornicatum (Fr.) Pat., Bull. Soc. Mycol. Fr. 5: 71. 1889..

 Description: Basidiocarp pileate, with a short stipe, woody. Pileus dimidiate, 12 cm wide, growth length 11 cm, up to 3 cm thick at the base. Upper surface glabrous, ochreous brown, brown, or black, occasionally laccate, concentrically sulcate; margin obtuse, somewhat lobed. Context brown, occasionally with dark brown resinous zones, 0.5-2 cm thick. Tube layer brown, paler than context, 0.3-1 cm thick. Pileus crust black, 0.5-2 mm thick, mainly composed of golden brown skeletal hyphae and swollen hyphal ends. Pore surface pale brown; pores suborbicular, ca. 5 per mm. Stipe lateral, about 2.5 cm long and 2 cm thick, concolorous with pileus surface. Context hyphal system trimitic; generative hyphae rare, colorless, nodose-septate, 2-4 μm diam., thin-walled; skeletal hyphae brown to pale brown, thick-walled to subsolid, with a few distal branches, skeletal stalks 5-7 μm diam., branches 3-5μm diam.; binding hyphae colorless, thick-walled to solid, branched, 1-2.5μm diam. Basidia not seen. Basidiospores ellipsoid, truncate at apex, usually guttulate, 9.5-11.5 × 5.5-6.5 μm; exospore colorless, thin; endospore thick, brown, separated from exospore by interwall pillars.

 Note: This species resembles Ganoderma limushanese J.D. Zhao & X.Q. Zhang, but has hard and dense structure of pilear crust (Zhao, 1989; Zhao and Zhang, 2000). The studied specimen was reported by Wu & Zhang (2003) as Ganoderma densizonatum J.D. Zhao & X.Q. Zhang, which might be a synonym of G. fornicatum.
