Hemileccinum hortonii, sometimes called Corrugated Bolete or Horton's Bolete, is a fungus of the genus Hemileccinum.
First described as variety corrugis of Boletus subglabripes by Charles Horton Peck in 1897, it was given its current name in 1971 by mycologists Alexander H. Smith and Harry Delbert Thiers.
The brownish cap is wide. The stem is tall and thick. The flesh is whitish and can stain light blue. The spore print is olive brown.
It resembles Boletus separans, Leccinum crocipodium, and L. rugosiceps. Hemileccinum subglabripes is similar, but differs by having a relatively smooth cap and a stem covered in tiny yellow .
The species can be found in the eastern United States from June to August. It grows under hardwood, mostly oak.
The mushroom is edible.
