Remarks (public):Basidiocarps of G. resinaceum may be confused with those of G. pfeifferi. which has a similar resinous layer on the upper crust, but this species has a dark brown to umber context and wider spores. Ganoderma lucidum has a lighter context without a darker zone above the tubes and no resinous layer on the crust. thus making it much more glossy and shiny even in older specimens. The spores also appear more coarsely warted than those of G. resinaceum.

Description:Ganoderma resinaceum Boud. - Bull. Soc. Mycol. Fr. 5:72, 1889.
Basidiocarps perennial, pileate, stipitate with a short, round expanding stipe or dimidiato to broadly attached, corky to woody. often large, 15 x 40 x 10 cm; upper surface flat. sulcate. glabrous, with a distinct crust in section, at first reddish and glossy, with age more reddish brown to bay and dull due to a excreted resinous layer which becomes yellowish when crushed and melts in a match flame; pore surface creamy white at first, later ochraceous to pale greyish with brown tints, pores angular to circular. about 3 per mm; context pale greyish brown with a darker zone just above the tubes, up to 6 cm thick at the base; tube layers concolorous with pore surface, up to 3 cm thick, usually without distinct stratification.
Hyphal system trimitic; generative hyphae hyaline, thin-walled, with clamps, 2-5 µm in diam, difficult to observe in dried specimens; skeletal hyphae abundant, thick-walled. yellowish brown, unbranched or with a few distal branches, 3-6 µm in diam, sometimes with lateral blunted outgrowths, these usually separated from the main stem by a simple septum; binding hyphae of the Bovista-type, hyaline to pale yellow, thick-walled, nonseptate, 3-5 µm in diam at the base, side branches long and whip-like; crust on pileus surface consists of a vertical palisade of amyloid, club-like hyphal ends apparently arising from generative hyphae, but clamps are small and solid and difficult o observe, length of these hyphal ends not determined. some at least 50 µm.
Cystidia or other sterile hymenial elements absent.
Basidia not seen.
Basidiospores ellipsoid, truncate at the apex. with a thick, brown endospore separated from a thin, hyaline exospore by interwall pillars, much smaller than those on spores of G. lucidum making the spores appear finely rough, 9-1 1.5 x 4.5-7 µm.
Type of rot. White heartrot in living hardwoods, especially Quercus spp.
Cultural characteristics. See Cerny 1979. who reports cultures of G. resinaceum produce chlamydospores like those reported for G. lucidum by Adaskaveg & Gilbertson (1986).
Sexuality. Heterothallic and tetrapolar (Adaskaveg & Gilbertson 1986). These authors also reported homocaryons of G. resinaceum from a European isolate were completely compatible with homocaryons of North American isolates of G. lucidum.
Substrata. Usually fruiting at the base of living Quercus, but also reported from living Aesculus, Alnus, Celtis, Cercis, Corn us, Fagus. Platanus, Populus, Robinia, Quercus, Salix, Sorbus, and Tilia, occasionally on dead trees. In the tropics on numerous hardwood genera.
Distribution. Southern and Central Europe with a few isolated localities in southern Denmark. Known also from North Africa. Asia and North America. Widespread in the paleotropics.
