Russula atropurpurea is a purple-capped mushroom with a stout stem, typically 3-6 cm tall and 1-3 cm wide. The cap is 4-8 cm in diameter, initially convex then depressed, and often has a wrinkled or cracked appearance. The gills are crowded, cream-colored, and attached to the stem. In East and Central Texas, Russula atropurpurea is commonly found in late summer to early fall, particularly under oak and pine trees, where it grows in association with the roots of these trees. It tends to favor acidic soils and can be abundant in areas with rich humus and adequate moisture.

Spores of a brittlegill mushroom Russula atropurpurea collected in Little Thicket Nature Sanctuary a day before. Texas, April 23, 2023Russula atropurpurea was observed in East and Central Texas on multiple occasions. On September 26, 2020, blackish purple brittlegill mushrooms were found on Caney Creek Trail in Sam Houston National Forest, specifically on the floodplain and along the Little Lake Creek Loop Trail. The mushrooms were also spotted in Little Thicket Nature Sanctuary in Cleveland, Texas, on April 22, 2023, with a dark reddish purple cap and pale yellow gills. A spore print collected from this location yielded yellow spores, confirming the species identification. The following day, spores of Russula atropurpurea were also collected in Little Thicket Nature Sanctuary, further supporting the presence of this fungus in the region. These observations suggest that Russula atropurpurea can be found in various habitats in East and Central Texas during different times of the year.
