Harrya chromapes, commonly known as the yellowfoot bolete or the chrome-footed bolete, is species of bolete fungus in the family Boletaceae. The bolete is found in eastern North America, Costa Rica, and eastern Asia, where it grows on the ground, in a mycorrhizal association with deciduous and coniferous trees. Fruit bodies have smooth, rose-pink caps that are initially convex before flattening out. The pores on the cap undersurface are white, aging to a pale pink as the spores mature. The thick stipe has fine pink or reddish dots (scabers), and is white to pinkish but with a bright yellow base. The mushrooms are edible but are popular with insects, and so they are often infested with maggots.
In its taxonomic history, Harrya chromapes has been shuffled to several different genera, including Boletus, Leccinum, and Tylopilus, and is known in field guides as a member of one of these genera. In 2012, it was transferred to the newly created genus Harrya when it was established that morphological and molecular evidence demonstrated its distinctness from the genera in which it had formerly been placed.
The species was first described scientifically by American mycologist Charles Christopher Frost as Boletus chromapes. Cataloging the bolete fungi of New England, Frost published 22 new bolete species in that 1874 publication.Rolf Singer placed the species in Leccinum in 1947 due to the scabrous dots on the stipe, even though the spore print color was not typical of that genus. In 1968, Alexander H. Smith and Harry Delbert Thiers thought that Tylopilus was a more appropriate fit as they believed the pinkish-brown spore print—characteristic of that genus—to be of greater taxonomic significance. Other genera to which it has been shuffled in its taxonomic history include Ceriomyces by William Alphonso Murrill in 1909, and Krombholzia by Rolf Singer in 1942;Ceriomyces and Krombholzia have since been subsumed into Boletus and Leccinum, respectively. Additional synonyms include Tylopilus cartagoensis, described by Wolfe & Bougher in 1993, and a later combination based on this name, Leccinum cartagoense.
