Pores very small, round to angular, white to cream when fresh, sometimes faintly yellowish or greenish when bruised; ~3–5 pores per mm

Cap

Irregularly rounded, convex to flattened or centrally depressed; often strongly fused with neighbouring caps; cream, apricot, salmon-orange to pinkish-buff or ochre, dry and smooth, sometimes cracking with age

Hymenium Attachment

Decurrent

Stipe

Short, stout, central to eccentric or lateral; whitish to cream or pinkish-buff, smooth, frequently fused with adjacent stipes in clustered fruit bodies

Spore print

Spore print white

Ecology

Ectomycorrhizal with conifers (spruce, boreal conifers); terrestrial on forest soil, gregarious and commonly forming large fused clusters; late summer to autumn

Edibility

Edible when young but generally considered mediocre; older specimens become tough and the taste may be bitter or cabbage-like

Fruit body

Fruit body medium to very large when clustered; individual stipes ~3–8 cm long and ~1–3 cm thick; fused masses may reach ~30–50 cm across

Dimensions

Cap ∅ ~3–20 cm individually

Flesh

Flesh cream to whitish, thick and fairly soft when fresh, becoming firm or hard when dry; often developing pale pink, salmon or brick-red tones on drying

Chemical reactions

KOH Purple on cap, pore surface and flesh

Odour

Pleasant to slightly fragrant

Taste

Cabbage-like, sometimes distinctly bitter

Microscopy

Spores ellipsoid to broadly ellipsoid, smooth, hyaline, weakly amyloid, ~4–5.5 × 2.5–4 µm; basidia 4-sterigmate; cystidia absent; hyphal system monomitic with frequent clamp connections and scattered gloeoplerous hyphae
