Remarks (public):F. rosea is the type species of Rhodofomes Kotl. & Pouz 1990. We feel that the pink colour of the context is insufficient as a base for a new genus. and retain P. roseus in Fomitopsis.

Description:Fomitopsis rosea (Alb. et Schw.:Fr.) Karst. - Krit. Finl. Basidsv. P. 306, 1889. - Boletus roseus Alb. & Schw., Consp. Fung., P. 251. 1805. - Polyporus roseus Alb. & Schw.:Fr., Syst. Mycol. 1:372, 1821.
Basidiocarps perennial, sessile, ungulate, tough-woody, up to 12 cm wide, upper surface at first tomentose, pale rose-pink; becoming glabrous and crustose with age, darkening to brownish black, becoming rimose; pore surface pale rose pink to pinkish brown, the pores circular to angular, 3-5 per mm; context pinkish brown, azonate to faintly zonate. tough-woody or fibrous, up to 3 cm thick; tube layers stratified, up to 2 cm thick, sometimes separated by a thin layer of context tissue.
Hyphal system trimitic; contextual generative hyphae thin-walled hyaline. with clamps 2-3.5 µm in diam; contextual skeletal hyphae thick-walled, with rare branching. nonseptate, 4-6 µm in diam; contextual binding hyphae thick-walled, much branched. nonseptate, 2-3.5 µm, inconspicuous; tramal hyphae similar.
Cystidia or other sterile hyrnenial elements lacking.
Basidia clavate, 4-sterigmate, 15-18 x 5-6 µm, with a basal clamp.
Basidiospores subcylindric to slightly ovoid. hyaline, smooth. negative in Melzer's reagent, 5.5-7.5 x 2-2.5 µm.
Type of rot. Brown cubical rot of dead conifers or rarely hardwoods.
Cultural characteristics. See Campbell 1938, Fritz 1923, Mounce and Macrae 1937, Nobles 1948. 1958, 1965. Stalpers 1978.
Sexuality. Heterothallic and bipolar (Mounce 1930, Nobles 1965).
Substrata. On conifers, especially Picea, but also noted on Abies. From North Sweden we have seen two collections from Alnus incana and Populus tremula respectively. In North America also reported from other hardwoods.
Distribution. A continental and montane species in Europe and follows the spruce in continental parts such as inner parts of the Scandinavian peninsula and also in the Central European mountains. In houses, mines and similar places widespread in lowland Europe from Great Britain and Denmark to Russia. Circumboreal in the northern conifer forests to East North America.
