Description

Name in North American Boletes: Boletus floridanus

Genus: Exsudosporus

  • Genus 2: Butyriboletus
  • Genus 3: Boletus

Species: floridanus

  • Species 2: frostii var. floridanus

Common Name:

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 moved this mushroom and frostii into a newly erected genus called “Exsudoporus” (“exsudo” from the droplets in young pores). It has since flip-flopped into the closely related Butyriboletus genus, and then been restored.

Edibility: Good.

CHEMICAL TESTS:

  • NH4OH (Ammonia): Cap surface turns black.
  • KOH: No data.
  • FeSO4 (Iron Salts): No data.
