Tinder fungus

Bordered polypore (Fomitopsis pinicola) is a mushroom of the Fomitopsis family, belongs to the Fomitopsis genus.


Bordered polypore (Fomitopsis pinicola) is a well-known fungus, belongs to saprophytes. It is characterized by perennial fruiting bodies that grow sideways, sessile. Young specimens have a rounded or hemispherical shape. Over time, the shape of this type of mushroom changes. It can be hoof-like or cushion-shaped.

Hat : usually of medium size, about 20-25 cm in diameter, but can easily reach 30 or even 40 centimeters (in old mushrooms). The height of the cap is up to 10 cm.

Leg : absent.

If wet weather sets in outside, droplets of liquid appear on the surface of the fruiting body of the bordered polypore. This process is called gutting.

Very young bordered polypores also gutt:

The pulp of the mushroom is dense, elastic, resembles a cork in structure. It can sometimes be woody. When broken, it becomes flaky. Light brown or light beige (chestnut in mature fruiting bodies).

Hymenophore : tubular, cream or beige. It darkens with mechanical stress, becoming gray or dark brown. The pores are rounded, well defined, small, 3-6 pores per 1 mm, about 8 mm deep

Season and habitat of the fungus

Bordered tinder fungi are referred to as saprophytes, provoking the development of brown rot. It is found in many regions, but most often in Europe and Russia.

Despite the epithet "Pinicola", from pinūs - pine, living on pines, pine, Bordered polypore grows successfully on dead wood and dead wood not only of coniferous, but also deciduous trees, on stumps. If a living tree is weakened, then the fungus can also infect it, starting life as a parasite, later becoming a saprophyte. The fruiting bodies of fringed polypores usually begin to grow at the bottom of the tree trunk.


Edible. Used to create mushroom flavored seasonings. It is a raw material for homeopathic medicines. It is successfully used in Chinese traditional medicine.

Similar types and differences from them

This mushroom is difficult to confuse with others. Unique concentric stripes of different colors on the surface of the cap are the decoration and calling card of this mushroom.
