Charcoal burner or Green 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 5-10 cm across, when young convex with an inrolled margin, with age becoming flattened with a slightly depressed center. The cap skin is smooth, slimy in wet weather, dry and matte in dry weather, peels easily 2/3 of the way to the center. Color: gray-green, grass-green, olive-green, deeper toward dark green at the center, paler toward the margin and fading to grayish. In mature specimens the margin has fine radial grooves.

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.

Gilled hymenophore — the gills are attached or free from the stem, moderately crowded, thin, brittle. Color: white at first, cream with a pale ochre tinge with age. Spore print creamy white to pale ochre.

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 4-8 cm tall, 1-2 cm thick, firm, cylindrical, hollow inside in old specimens. Color: white to creamy white, without noticeable spots. Surface smooth with fine lengthwise wrinkles. No ring, no volva — a key distinguishing feature from the death cap.

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, brittle, white, when cut does not change color or slowly turns yellow. Smell faint, pleasant, fruity-mushroomy, taste mild, with no bitterness or acridity (tongue test).

Faint, pleasant, fruity-mushroomy, neutral.
