Cap: 3-6 cm in diameter, at first kidney-shaped, then lingual, ear-shaped or shell-shaped, with an edge turned down, sometimes rather strongly turned. In adult mushrooms, the surface of the cap is whitish-brownish, yellowish-reddish or dark pale yellow, matte, velvety, longitudinal fibrous, fine-scaled. The caps often grow together at the base and form dense groups, resembling shingles. Some sources indicate the size of the cap as much as 23 centimeters, but this information seems to the author of this article somewhat dubious.
Leg: lateral, rudimentary, about 1 centimeter, or may be completely absent. Dense, brownish, brownish or even almost black.
Plates: descending, frequent, wide, with an uneven serrated edge, typical of saw-leaves. Whitish, whitish-beige, then slightly reddening.
Spore powder: white.
Flesh: white, whitish. Tough.
Smell: pronounced mushroom.
Taste: acrid, bitter.
The mushroom is considered inedible due to its pungent taste. This 'pungency' does not go away even after long boiling. No data on toxicity.
Season and distribution
Grows on dead trunks and stumps of coniferous and deciduous species. Not often found, from July to September-October. Distributed throughout Europe, the European part of Russia, the North Caucasus.
It is believed that wolf sawnose can be confused with oyster mushroom, but this 'feat' is clearly only for inexperienced mushroom pickers. Bear saw-leaf (Lentinellus ursinus) – very similar. Differs in the complete absence of a leg.
