The thick stipe has fine pink or reddish dots (scabers), and is white to pinkish but with a bright yellow base.

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.

[2] Rolf Singer placed the species in Leccinum in 1947 due to the scabrous dots on the stipe,[3] 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.

[7] Additional synonyms include Tylopilus cartagoensis, described by Wolfe & Bougher in 1993,[8] and a later combination based on this name, Leccinum cartagoense.

[13] The flesh is white, and does not stain blue when it is bruised or injured (an important diagnostic feature of many bolete species).

[16] Spores are roughly oblong to oval, smooth, hyaline (translucent) to pale brown, and measure 11–17 by 4–5.5 μm.

Pleurocystidia (found on the tube walls) are roughly cylindrical to fuse-shaped with rounded tips, and measure 37–50 by 5–8 μm.

[1] Harrya chromapes is an ectomycorrhizal species,[18] and its fruit bodies grow singly to scattered on soil.

[13] In Costa Rica, where the species associates with oak, it has been recorded from the Cordillera Talamanca, the Poás and Irazu Volcano.

[20] In Asia, it is known from India (West Bengal),[21] Taiwan,[22] Japan,[23] and in China, where it associates with trees from the beech and pine families.

[25] The cottontail rabbit species Sylvilagus brasiliensis has been recorded feeding on the mushrooms in Costa Rica.
