Rubroboletus eastwoodiae

Rubroboletus eastwoodiae, sometimes (but inaccurately) called satan's bolete, is a possibly toxic basidiomycete fungus of the bolete family.

The cap is 6–25 centimetres (2+1⁄2–10 in) wide, convex, olive-colored, pinkish in age, dry, has margin that curves inward then expands, and yellowish flesh. The stalk is 7–15 cm (3–6 in) tall and 3–6 cm (1+1⁄4–2+1⁄4 in) wide. The flesh turns blue when cut. The spores are olive-brown, elliptical, and smooth. The spore print is olive brown.

It is closely related to Rubroboletus pulcherrimus. It looks similar to but is genetically distinct from the European species R. satanas. It is also similar to R. pulcherrimus and Suillellus amygdalinus.

It occurs under oak on the West Coast of the United States from November to January.

The edibility of the species is unknown; it may be poisonous.
