The genus Russula may usually be recognised by its brittle character, added to its fleshy stem and the fact that the lamellae are usually joined to the stem. Bright clear reds and purplish hues prevail, but several species exhibit a green colour, or an approach to green. The spores are white or yellowish, and the flesh never exudes a milky or coloured juice.

Smooth, white, and solid, or somewhat softer within. 1-2 inches long. Spores - White, rough, nearly globose. Flesh - White ; mild in taste.

Variable Russula (Edible)
Cap or Pileus - Variable in colour. Greenish or pinkish grey, but fleshy, firm ; slightly convex, then depressed ; smooth, and polished, the very thin skin disappearing. Margin thin, smooth, or with slightly depressed lines closely placed.
Stem or Stipe - Solid, firm, smooth, shining white, the apex oc-casionally dilated in the form of a cup.
Annulus or Volva - None.
Gills or Lamella - Narrow, crowded, forked ; white ; of different lengths.
Spores - White.
Flesh - White ; mild in taste.
