Xerocomellus dryophilus, commonly known as the oak-loving bolete and formerly known as Boletus dryophilus or Xerocomus dryophilus, is a basidiomycete fungus in the family Boletaceae native to North America.

It appears to only occur under the coast live oak (Quercus agrifolia),[1] and is only found in California, where it is one of the most common boletes in the Los Angeles and San Diego counties.

[2] It is commonly parasitized by Hypomyces chrysospermus.

[2] It was transferred to the new genus Xerocomellus in 2014.

This epithet had been previously applied to a European species, now described as Xerocomellus redeuilhii.
