Remarks (public):This species is closely related to D. confragosa and may be interpreted as a southern ecotype. The main characters separating it from D. confragosa are the occurrence of lamellae, and the often rather small basidiocarps with an almost completely reddish pileus.

Basidiocarps annual, pileate, sessile, often semicircular and imbricate, applanate, up to 14 cm wide and long, 1-3 cm thick at the base; pilear surface at first ashy grey to pale brown, later becoming red to deep bay in zones from the base or in distinct spots, glabrous, sulcate and concentrically zonate; pore surface brown, poroid to lamellate, but never entirely poroid, lamellae dichotomously branched, pores usually more prominent close to the base, lamellae more pronounced towards the margin, sometimes with concentric poroid zones, pores angular to sinuous, 1-2 per mm, 0.5 to 1 mm wide, up to 3 mm long, lamellae 10-17 per cm measured tangentially, tubes or lamellae up to 1.4 cm long; context pale brown, tough and homogeneous with a thin, dark cuticle from the base in deep bay specimens. Hyphal system trimitic; generative hyphae with clamps, thin-walled, hyaline, with occasional branching, 2-6 µm wide; skeletal hyphae light brown, thick-walled, with rare branching, 4-7 [tm wide; binding hyphae yellowish to brown, thick-walled, frequently branched, 2-4.5 µm wide.
Dendrohyphidia present when basidia are absent, hyaline, thin-walled at the tip, brown and thick-walled at the base, up to 30 µm long.
Basidia and basidiospores as in D. confragosa.
