Charcoal burner or Greencracked brittlegill

Cap 5-15 cm across, when young hemispherical, with age becoming flattened with a slightly depressed center. The cap skin is smooth, slimy in wet weather, dry and matte in dry weather, peeling 2/3 of the way to the center. Color very variable — violet-blue, green-gray, olive-violet, brownish violet with yellow patches. In a single cluster of fruiting bodies you'll often see caps in different shades. Deeper in the center, paler toward the margin, with fine radial grooves.

Cap 5–15 cm across, spherical in young mushrooms, then flat or slightly depressed. The surface is matte, dry, cracked into small polygonal patches — a characteristic “mosaic” pattern. Color green, grayish green, sometimes with yellowish or grayish zones. The margin is blunt.

Gilled hymenophore — gills adnate or free from the stem, partly forked near the stem, moderately crowded. UNIQUE FEATURE: the gills are flexible and springy and don't break when pressed — run your finger over them and they bend and spring back (unlike all other brittlegills, whose gills are brittle and crumbly). Color pure white to creamy white. Spore print white.

Gills crowded, even, brittle, white. They don't change color when damaged. Spore print white. The gills snap easily under your finger — the brittleness typical of the genus Russula.

Stem 5-10 cm tall, 1.5-3 cm thick, firm, fleshy, cylindrical, with a small cavity in old specimens. Color white to cream, sometimes with a faint violet tinge toward the base. Surface smooth with fine lengthwise wrinkles. No ring, no volva.

Stem 4–10 cm tall, 1.5–3 cm thick, firm, evenly cylindrical or slightly narrowing toward the base. The surface is white, smooth or slightly wrinkled. No ring and no volva — an important safety feature.

Flesh firm, fleshy, pure white, does not change color when cut — a characteristic of the species. Smell faint, pleasant, fruity-mushroomy, taste mild, sweetish and nutty, with no bitterness or acridity.

Flesh firm, white, crunchy, crumbles easily — the so-called “brittlegill” brittleness. It doesn't change color when damaged and releases no milk. The taste is mild and nutty, without bitterness — one of the few brittlegills that can be eaten raw without danger.

Faint, pleasant, fruity-mushroomy, neutral.

Smell unobtrusive, pleasant, faintly nutty. It lacks the sharp or unpleasant notes typical of some poisonous brittlegills. When cooked, the aroma grows stronger, taking on warm woodland notes.
