May to November. _McIlvaine._ It is one of the first toadstools I experimented upon. I have been constant to it.

Mixed woods. Albany. Cattaraugus and Steuben counties. September and October. According to the description the typical plant has the pileus incarnate and the stem rosy-red, but in the American plant the pileus is generally more clearly red and the stem white, though this is often varied by reddish stains. _Peck_, 44th Rep.
