Fellinus rusty-brown is a woody species. It usually grows on a bunch of conifers, prefers spruce, pine, fir. Also commonly found in blueberries.
Usually grows in the mountain forests of Siberia, but in the European part of our country is quite rare. On wood, the settlements of Phellinus ferrugineofuscus cause yellow rot, while stratification along the annual rings occurs.
Fruit bodies are prostrate, have a very porous hymenophore.
In their embryonic state, the bodies look like small pubescent tubercles of the mycelium, which grow rapidly, merge, forming fruit bodies extending along the wood. Bodies often have stepped or low pseudopylaea. The edges of the fungus are sterile, lighter than the tubes.
The surface of the hymenophore is red, chocolate, brown, often with brown tints. The tubules of the hymenophore are single-layered, can be slightly layered, straight, sometimes open. The pores are very fine.
Belongs to the inedible category.
