Common names: crowded brittlegill, Dense-gilled Russula.
Extract from Wikipedia article: Russula densifolia, commonly known as the crowded russula or the reddening russula, is a species of agaric fungus in the family Russulaceae. It was first described in 1833 and given its current name in 1876. A widespread species, it is found in Asia, Europe, and North America, where it fruits on the ground in mixed and deciduous forests. Fruit bodies (mushrooms) are robust and squat, with caps up to 14.5 cm (5.7 in) in diameter, and stems that are 2–7.5 cm (0.8–3.0 in) long by 1.2–2.5 cm (0.5–1.0 in) thick. The mushrooms are characterized by the red and then black color changes that occur in the flesh when it is bruised, and a relatively thick cap cuticle. Although the mushroom is sold as an edible species in some areas of Asia, it is mild to moderately toxic, and may cause gastrointestinal upset if consumed. Several bioactive compounds have been isolated and identified from the mushroom.

Russula densifolia is a medium-sized mushroom with a cap that ranges from 3-8 cm in diameter, typically reddish-brown to purple-brown in color, and often has a depressed center. The gills are closely spaced, white to cream-colored, and attached to the stem. The stem is usually 3-6 cm long, 0.5-1.5 cm thick, and white. In East and Central Texas, Russula densifolia is commonly found in association with oak trees, particularly under live oaks and post oaks, during the summer and fall months. It tends to thrive in rich soils with abundant organic matter, often fruiting in large numbers after heavy rainfall events.
