Greasy green brittlegill or Charcoal burner

Cap 5-12 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 green-olive, olive-gray, gray-brown, deeper in the center to dark green. Mature caps have fine radial grooves at the margin.

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.

Gilled hymenophore — gills adnate or free from the stem, moderately crowded, thin, with characteristic forking near the stem — a diagnostic trait. Color pure white to creamy white. Spore print white.

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.

Stem 4-8 cm tall, 1.5-2.5 cm thick, firm, cylindrical, hollow in old specimens. Color white to cream, with faint gray-cream patches in old specimens. Surface smooth with fine lengthwise wrinkles. No ring, no volva.

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.

Flesh firm, brittle, white, turns faintly pink when damaged — a reaction typical of the species. Smell faint, pleasant, fruity-mushroomy, taste mild, sweetish and nutty, not bitter (tongue test).

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.

Faint, pleasant, fruity-mushroomy, neutral-sweetish.
