Description

Genus: Boletus

Genus 2: Ceriomyces

Species: aureissimus var. castaneus (see the Science Notes below)

Species 2: auripes var. castaneus

Tells: Velvety purple-brown cap. Yellow pores age darker & DNS. Oft-bulbous, yellow to bright-yellow stem usually has yellow netting on top.

Other Information: Regular aureissimus has a yellow/gold cap. Mentioned in Boletes of Eastern North America, p. 93, as “Ceriomyces aureissimus var. castaneus.”

Science Notes: Is this an actual species? Probably not. It’s origin goes back to a throwaway comment in the original description of regular aureissimus, which could easily have been (a/k/a probably was) a relatively standard form of what we now call B. auripes. We await guidance by them as knows better, but in the end it’s going to require DNA testing of the original type specimens at the Florida State University herbarium. This goes to a longer and more thorough discussion at Mushroom Observer.

Edibility: Good.

CHEMICAL TESTS:

NH4OH (Ammonia): No data.
KOH: No data.
FeSO4 (Iron Salts): No data.
