Extract from Wikipedia article: Rhodocollybia maculata, common name Spotted Toughshank, is a species of fungus in the Marasmiaceae family of mushrooms.
Rhodocollybia maculata is a species of fungus that belongs to the family Omphalotaceae. It is a small to medium-sized mushroom with a convex to flat cap, typically 1-4 cm in diameter, and a slender stem. The cap is often spotted or streaked with pinkish-brown to reddish-brown markings on a lighter background. In East and Central Texas, Rhodocollybia maculata can be found growing in clusters or scattered on the ground in wooded areas, particularly under oak, pine, and maple trees. It typically fruits from spring to fall, with peak activity during the summer months. The fungus is considered edible, but its quality is often reported as variable.
