Description:Polyporus rhizophilus (Pat.) Sacc., Syll. Fung. 11:82 (1895). Fig. 3b
Basidiocarps centrally stipitate. Pileus circular to semicircular, plane to convex, 0.5-2.2 cm in diameter; pileus surface wrinkled, grayish-orange to grayish-brown (10YR7-8/2-4), margin acute, entire. Stipe cylindrical, up to 1.5 cm long, up to 4 mm in diameter, wrinkled, grayish-orange to pale orange (10YR7-9/2-4), rarely with a cuticle near the base. Context soft corky, brittle, white to pale orange (10YR9/4), without a crust. Pore surface concolorous with the stipe, pores angular, (1-)2-3/mm, dissepiments thin, mostly entire. Tubes concolorous with pore surface.
Hyphal system dimitic with generative hyphae and skeletal-binding hyphae in the trama, monomitic to dimitic in the context. Contextual generative hyphae 2.5-6 ?m in diam., thin-walled, hyaline, with clamp connections. Contextual skeletal-binding hyphae mostly solid, branched, interwoven, hyaline, 2-5 ?m in diameter, often sparse, lacking in the marginal areas. Tramal generative hyphae 2-4 ?m in diameter, thin-walled, hyaline, with clamp connections. Tramal skeletal-binding hyphae thick-walled to solid, frequently branched, interwoven, hyaline, 1-3 ?m wide, dextrinoid or nondextrinoid. Cuticle on stipe composed of coralloid-binding hyphae with clavate tips, hyphae nonagglutinated, easy to loosen. Basidia clavate, 25-32.5 x5-7 ?m, with a basal clamp, 4-sterigmate. Basidiospores cylindrical to fusiform, hyaline, nondextrinoid, 7-11 x 2.5-4 ?m, L = 9.14 ?m, W = 3.2 ?m, R = 2.25-4, r = 2.86 (n = 77/3).
