🔬 Morphology

Cap

Hen of the woods

The fruit body is a large bushy cluster of 30-200 fused, frond-like “caps” on a shared branching trunk. Individual caps are 4-10 cm wide, fan-shaped, thin, with a wavy margin. Color gray-brown or gray-olive, paler (ash-gray) in young specimens, dark brown in old ones. The surface is smooth or finely radially fibrous. Total weight of the cluster is 2 to 15 kg.

Umbrella polypore

Large bushy fruiting body 20-50 cm across, with 50-200 small caps on a shared stem. Individual caps 1-4 cm across, round, convex-flat with a slightly depressed center. The surface is smooth or with fine felty fibers. Color gray-brown, ochre-brown, with fine radial fibrous patterns. Lighter when young, darker when old.

Hymenophore

Hen of the woods

pored hymenophore — an important feature that sets it apart from frond-like gilled species. The tubes are short (2-4 mm), uneven, running down onto the stalks of the caps. Color whitish to yellowish. Spore print white.

Umbrella polypore

Tubular hymenophore — fine, tiny white pores on the underside of the caps (1-3 pores/mm). Color white to cream, running down the stem. Spore print white.

Stem

Hen of the woods

The shared trunk of the cluster is thick, fleshy, whitish and repeatedly branched, each branch ending in a separate cap. The cluster is 15-30 cm tall. There are no separate stems as such — it is a single, segmented structure.

Umbrella polypore

Each little cap has a thin central stem 1-3 cm tall and 0.3-0.5 cm thick, white or grayish white. Shared branching stem at the base joins all the little caps and grows down into the underground sclerotium.

Flesh

Hen of the woods

flesh is white to pale cream; springy and fleshy in young ones, stringy and tough in old ones. Does not change color when cut. Young flesh has a pleasant nutty taste, similar to chicken.

Umbrella polypore

Flesh pure white, brittle when young, somewhat tough when old. Does not change color when cut. Smell pleasantly mushroomy with a hint of flour or cucumber, taste mild, sweetish, not bitter.

Smell

Hen of the woods

Pleasant mushroomy smell with a nutty note, with a hint of fruit in some clusters. Mild taste, with subtle nutty and woody notes.

Umbrella polypore

Pleasantly mushroomy with a hint of flour and fresh cucumber. A characteristic feature of the species.
