This Russula has a green cap 2 to 3-3/8 inches wide, convex to flat, often depressed in the center, with faint radial lines along the edge. It's slightly sticky when wet, accounting for its common name. The brittle flesh is white.
The broad white (sometimes tinged with yellow) gills, which are close together, attach to the stalk, sometimes descending it slightly. The spore print is orange-yellow.
The smooth, dull yellowish-white stem is 1-5/8 to 2-3/8 inches long, 3/8 to 3/4 inches long, sometimes tapering toward the base.
