Remarks (public):The neotype and paraneotypes were all collected within a few kilometers of each other, south of Lisbon. Brotero's (1804) description does contain some discordant elements with regard to the neotype, i.e. "pulvinatus" (cushion shaped) and "subtus lateritius" (brick-colored below). However, if the ontogeny of basidiomata for this species is considered, we can envision a somewhat cushion-shaped basidioma in early stages of development (1-2 yr), accompanied by an undersurface that at some point in its annual development would be dull reddish-brown (perhaps near dull brick-colored).
There is a specimen that is a potential candidate for neotype in the herbarium of Pereira Coutinho (Flora Lusitanica) no. 6371 (LISU), labelled as Trametes pini (Thore) Fr. and inscribed "Nos Pinheiros: Pinhal de Leiria". Microscopically, this specimen is quite similar to the neotype. Macroscopically it is ungulate to pulvinate (now divided into several mounted pieces) . However, it was deemed important to select neotypic material from which cultures have been obtained, thus providing a basis for more detailed comparisons, at the molecular and physiological levels, between geographically separated populations of the Phellinus pini-complex.

Basidioma 12 x 7 x 5 cm, sessile, pileate, usually solitary, woody, becoming perennial. Upper surface at first ferruginous brown (near 7.5YR 5/2) and hirsute, then with a black pellicle up to 1.5 mm thick, radially and concentrically cracked, sulcate, overlain by a uniformly dull green effuse, lichenized discomycetous growth. Margin ferruginous brown (near 7.5YR 4/4), acute to somewhat rounded, 3-4 mm wide. Pore surface dull yellowish-brown with a faint citrine cast (near 2.5Y 4/4). Pores 1-2(-3) per mm, round to mostly angular with some elongated radially. Tubes indistinctly stratified, individual strata up to 9 mm thick, individual tubes filled with brown hyphae (more rarely white). Context up to 2 mm thick, concolorous with the margin and somewhat darker than tramal tissues, appearing distinctly radially oriented when the surface pellicle is removed. Contextual skeletal hyphae (3.5-) 4-5 µm diam, becoming thickwalled to solid, septa absent or with some adventitious septa present, unbranched, dull brown. Contextual generative hyphae of two kinds, some 2-2.5 µm, thin-walled, septate, branching frequently; others 3.5-5 µm diam, thin-walled but some becoming sclerified, septate, branching infrequently, pale brown. Tramal skeletal hyphae 3-4 µm diam, aseptate, thick-walled to solid, dull brown, interwoven to somewhat parallel. Tramal generative hyphae 1-2 µm diam, septate, thin-walled, frequently branched, hyaline. Tramal setal hyphae infrequent, 70-75 x 10-12.5 µm, thick-walled, dark ferruginous brown. Hymenial setae (30-)40-50(-60) x 15-30(-40) µm, form highly variable from subulate, ventricose, to rostrate, dull ferruginous brown, thick-walled. Basidia 8-10 x 5-6 µm, broadly clavate to obovate, basidial honeycomb structure absent from the hymenium. Basidiospores 56(-6.5) x 4-5(-5.5) µm, mostly broadly ellipsoid to sometimes subglobose, often tapering towards the apiculum and flattened adaxially, some with thickened walls, hyaline in 5% KOH and H20 (a few pale rusty brown spores present), negative in Melzer's reagent, contents and walls cyanophilous.
