Common Name: “Field Bolete”
Tells: Found in lawns and roadsides. Yellow stem- & paler cap-flesh both stain greenish blue. Yellow pores age to greenish- or olive-yellow. Never gets bigger than 1-1/2″ across.
Other Information: Red cap often has pinkish tones but can be straight red, brown, or tan. Cap may crack in age but not as much as H. rubellus. Yellow stem gets darker going down, typically w/ red-orange dots toward the bottom. Yellow mycelium.
Science Notes: DNA testing moved this mushroom into the newly erected genus “Hortiboletus” (“hortus” = “garden,” a typical environment for the members of this genus).
