Name in North American Boletes: Boletus floridanus
- Genus 2: Boletus
- Genus 3: Exsudosporus
- Species 2: frostii var. floridanus
Tells: Viscid red cap. Yellow cap flesh blues. Red stem very netted, esp. high up. Red or orange-red pores stain blue, w/yellow drops on babies.
Other Information: Likes sandy soil under oaks and sometimes pine. A red-pored, blue-staining, but very edible mushroom. Has an acidic tang when cooked. A southern equivalent to But. frostii.
Science Notes: DNA testing and its odd features initially moved this mushroom and frostii into a newly erected genus called “Exsudoporus” (“exsudo” from the droplets in young pores), but later work has suggested they belong with the butter boletes.
