Russula brevipes

Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. The fruit bodies are white and large, with convex to funnel-shaped caps measuring 7–30 cm (3–12 in) wide set atop a thick stipe up to 8 cm (3 in) long.

Forms of the mushroom that develop a bluish band at the top of the stipe are sometimes referred to as variety acrior.
