Extract from Wikipedia article: Russula cyanoxantha, synonymous with R. xyanoxantha, commonly known as the charcoal burner, is a basidiomycete mushroom, distinguished from most other members of the genus Russula by the fact that its gills do not split, but are soft and flexible. It is one of the most common species of Russula in Europe.
Russula cyanoxantha is a species of mushroom characterized by its purple to blue-purple cap, white gills, and white spores. In East and Central Texas, it typically fruits from June to October, often in association with oak and pine trees. The cap ranges from 3-8 cm in diameter, and the stem is white, stout, and up to 6 cm long. This species is considered edible and has been found in various habitats, including woodland edges, savannas, and urban parks, throughout the region.
