Extract from Wikipedia article: Xanthoconium purpureum is a species of bolete fungus in the genus Xanthoconium. It was described as new to science in 1962 by Wally Snell and Esther Dick in 1962. It is found in eastern North America, where it fruits under oak, sometimes in oak-pine forests.
Xanthoconium purpureum is a species of bolete fungus characterized by its purple to reddish-brown cap, white to yellow pores, and stout stem. In East and Central Texas, it typically fruits in late summer to early fall, often associated with oak trees, particularly live oak and post oak. The fungus can be found in a variety of habitats, including woodland edges, savannas, and urban landscapes, where oak trees are present. Specimens from this region usually have caps ranging from 3-8 cm in diameter and stems that are 4-10 cm tall and 1-3 cm thick.
