The stem is stout, nearly cylindric, firm but spongy in the center and colored like the cap, but generally a little paler. There is a variety in which the stem is white and the cap deep red. In other respects it is like the typical form. Its name is Russula ochrophylla albipes.

The ochery-gilled Russula grows in groups under trees, especially oak trees, and should be sought in July and August. Peck, 51st Rep. N.Y. State Bot.
