Description

Genus: Boletus

Genus 2: Butyriboletus (to which it will probably be moved when a specimen can be found for testing)

Species: speciosus

Common Name:

Tells: Red cap browns in old age & stains blue. Yellow pores & pale yellow cap flesh blue instantly. Well-netted stem yellow above & red by base. Uncommon.

Other Information: North American Boletes says the cap stains yellow, but that appears to be a typo based on all the photos I’ve seen. Think of a blue-staining, well-netted Bicolor Bolete & you’re pretty much there.

Edibility: Good.

CHEMICAL TESTS:

NH4OH (Ammonia): No data.
KOH: Cap flesh turns orange.
FeSO4 (Iron Salts): Cap flesh turns grayish.
