Rusty brown spore print. Gills are a beautiful deep lilac color when young, although rarely captured. Wrinkled (corrugated) cap; orange/brown coloration, sometimes with hint of red. Stem is a off white color with yellow and brown tones at times; equal in thickness with a slightly swollen base. Can be abundant in summer under oak and beech. Seems to have a relationship with America beech trees. Mild odor and taste.
