- Genus 2: Boletus
- Species 2: pallidoroseus
Common Name: Bouillon Bolete
Tells: Think “muddled bicolor.” Firm, yellow flesh often smells like beef bouillon & stem flesh may slowly stain green from the base up and/or stem skin in.
Other Information: Cap is usually more pinkish-red (or a tan) than true red, and stem not the distinct red-and-yellow of a Bicolor. Yellow pores bruise blue & age toward orange/brown. White to yellow cap flesh may blue slowly & faintly. May grow in united clusters or as individuals. Your author has personally found specimens with a cap >11″ across.
More Notes: Not uncommon in the Pittsburgh area, where in the 2015 Spring we observed a slow (5-10 minutes), progressive (from the base up), blue-green stain in the stem flesh, which faded 10-20 minutes later. Later in the year the green was more erratic. Reports from other regions confirm similar progressive staining, often near the stem skin more than the base. We also find a mushroom believed to be pallidoroseus but with a true “red” coloration rather than the more typical pink. DNA analysis to confirm the ID of the true-red specimens are in progress.
Edibility: Edible, with little flavor but a fantastic texture. Try them roasted or smoked!
