🔬 Morphology

Cap

Bitter coral

A bushy fruiting body with no cap. Size 8-12 cm tall, 6-10 cm across. Branches lacy, moderately thick, with a characteristic violet-gray to dingy lilac color near the base; higher up yellowish-cream with ochre tips. The dark color of the base is a diagnostic feature.

Rosso coral

There's no cap in the usual sense — the mushroom forms a bushy, coral-like fruiting body. Overall size: 10-20 cm tall, 15-30 cm across, shape compact and rounded to cushion-like. It consists of a thick shared trunk at the bottom and numerous branching "fingers" (branchlets) on top. The base is white to cream, the branchlets pale cream with characteristic pinkish-red or wine-purple tips — a diagnostic feature.

Hymenophore

Bitter coral

The spore-bearing layer covers the surface of the branches. Spore print ochre-yellow.

Rosso coral

The spore-bearing layer covers the surface of the "fingers" (no gills or pores). Spore print ochre to yellowish.

Stem

Bitter coral

Shared base short, 2-4 cm tall, 1-2 cm across, violet-gray to dingy lilac, dividing into numerous forked branches.

Rosso coral

The shared base of the cluster is thick, fleshy, white, 3-8 cm tall, 4-6 cm across. Upward it divides into numerous branches, then into smaller branchlets with pink tips. The surface of the base is smooth, white, yellowing with age.

Flesh

Bitter coral

Flesh firm, whitish at first, quickly darkening to blue-violet or violet-black when damaged — a characteristic reaction and an important diagnostic. Taste bitter, astringent.

Rosso coral

Flesh firm, white, marbled, becoming rather tough and fibrous. It doesn't change color when cut — an important diagnostic feature (toxic ramarias may darken). Smell pleasant, fruity, sometimes with a hint of radish.

Smell

Bitter coral

Faintly mushroomy with a hint of radish or damp soil.

Rosso coral

Pleasant, fresh, fruity-mushroomy, with a hint of radish in young ones. Not sharp, no chemical notes.
