Perenniporia martius (Berk.) Ryv., Norw. J. Bot. 19: 143. 1972.

 Description: Basidiocarp annual to perennial, sessile, applanate, effused-reflexed, corky to woody. Pileus up to 40 cm wide, up to 10 cm thick at the thick base, semicircular dimidiate, flabelliform, flat to convex; upper surface glabrous, concentrically zoned, sulcate, concentrically and irregularly cracked, white to cream, soon covered by a pinkish brown to dark cuticle starting from the base, blackish brown, dusky brown, hair brown, chestnut brow. Pores round, angular to irregular, 3-5 per mm; pore surface cream, vinaceous-buff, avellaneous, hyphal system dimitic, generative hyphae with clamps, hyaline, thin-walled, 1.5-3.0 μm wide, skeletal hyphae dominant, dexrinoid, thick-walled, to solid, hyaline to light brown, up to 5.0 μm wide. Cystidia tubular to venticose, thick-walled, apex obtuse or acute to submucronate, often subconic, often rather thickly rugose-granular at the apex with a hyaline amorphous incrustation, hyaline, dextrinoid. Basidiospores subglobose to pip-shaped, not truncate, hyaline, thick-walled, smooth, dextrinoid, 6.2-8.7 × 3.8-6.3 μm.
