The fruiting body of Fomitopsis pinicola is called the conk. It is a woody, pileate fruiting body with pores lined with basidia on its underside. As in other polypores, the fruiting body is perennial with a new layer of pores produced each year on the bottom of the old pores.

Fomitopsis pinicola also grows mainly on Picea, but it has smaller pores (4–6 per mm), a brownish orange to black pileal surface at base and buff-yellow to cinnamon toward the margin when fresh, and is distributed in Europe.

Pore Surface: Whitish to slightly yellowish; not bruising significantly; with 3–4 round pores per mm; annual tube layers usually fairly distinct, up to 8 mm deep. Stem: Absent. Flesh: Whitish to slightly yellowish or brownish; leathery to woody. Odor: Strong and fragrant or sour when fresh. Chemical Reactions: KOH on flesh red to brownish red.

Fomitopsis pinicola is a brown rot Basidiomycete species commonly collected on dead conifer trees. An orange or red band is nearly always present between the older annual layers and the current layer, making this polypore instantly recognizable. It is inedible but used for making tincture and tea.

2014年8月26日 · Fomitopsis pinicola is an abundant saprotrophic fungus found on decaying logs throughout temperate regions of the Northern Hemisphere. Phylogenetic studies have addressed the relationship of F. pinicola to other wood-rotting fungi, but pan-continental varia-tion within F. pinicola has not been addressed using molecular data.

Its pores bruise brown, as opposed to yellow-buff, lacks a brightly colored marginal band, and has brown rather than pale yellow spores. Fomitopsis pinicola conks may grow for many years, each season adding a new layer of tubes. Counting the tube layers, somewhat analagous to counting tree rings, gives a rough idea of the age of the conk.

Pores and Tubes. Inside the fruiting body the flesh is hard and pale brown, while the spore-bearing surface has minute roundish pores, spaced at 3 to 4 per mm; the pores are cream at first (and bruise yellowish buff) but with age they become brown. Spores. Ellipsoidal to cylindrical, smooth, 6-8 x 3.5-4μm; inamyloid. Spore print

To the genus Fomitopsis are ascribed pluriennial basidiomes, at times even annual, sessile, growing on the wood, of mainly woody consistency; smooth sterile surface, zonate or grooved with distinct cutis; white, cream or pink context, with concolorous tubules and pores. The hyphal system is trimitic, the structural and connective hyphae have a ...

The fruiting body of Fomitopsis pinicola is called the conk. It is a woody, pileate fruiting body with pores lined with basidia on its underside.

The pores are whitish when young and become somewhat brownish in age.

Daedaleopsis confragosa (often growing in similar locations – this fungus has maze-like pores and often blushed reddish brown); Ganoderma australe (brown flesh). Significance Attributed to a cubical brown rot of the wood.
