Rhodofomes roseus explained

Rhodofomes roseus is a species of pink polypore found in western North America[1] and Europe. This is a close relative of another species of pink conk, the rosy conk (Rhodofomes cajanderi). While R. cajanderi is a plant pathogen, R. rosea is a detritivore.

Habitat

Rhodofomes roseus grows in western North America, most often in spruce forests. Specimens from Vancouver Island, Prince George, and Wells Gray Park have helped characterize the species. This conk grows exclusively on dead wood, with a preference for logs of Picea, Pseudotsuga. or Populus species. It causes a brown cubical rot.

Identification

Rhodofomes roseus is a perennial fungus. It is sessile, meaning it is immobile and attached at the base without the presence of a stalk or peduncle. It often grows in a hoof or fan shape, with a smooth surface. The top of the conk can be a pale pink fading to a grey or brown colour, while the bottom is a pale pink. The inside of the conk, known as the context, is fibrous and woody, and may have layers of brown or pink colour. It has round pores, with 3-5 pores per millimeter.

Rhodofomes roseus is thicker than its close relative, Rhodofomes cajanderi
