Description

Fat brown bun cap over a swollen white stem with a fine net (reticulum) near the top. Underside is a sponge of pores, never gills. Pores start white, age yellow-olive. Flesh does not stain blue in true B. edulis.

Where it grows

Conifer and mixed woods, often near spruce.

How to find it

Mycorrhizal with spruce, fir, pine, and birch. Hunt after cool rains in late summer–fall. Look on forest edges, old roads, and mossy benches. Check every button for maggots by slicing the stem.

How to pick

Cut high enough to leave the base. Slice immediately — if the sponge is green and the stem is tunneled, dry it or leave it. Never soak.

Medicinal notes

Culinary. High protein for a fungus. Not a medicinal staple.

Psychoactive / controlled

None.

Law

Legal food. Commercial permits required on most public forests.

Lookalikes

  • Bitter bolete (Tylopilus felleus)

    Pink pores, strong bitter taste. Not toxic but ruins a pot. Nibble-and-spit test only after you know the genus.

  • Blue-staining boletes

    Some are edible, some are not. Instant deep-blue stain + red pores = do not eat.
