Tells: Bitter white cap flesh. Violet cap skin ages through pink to tan, bruising violet. Pinkish, yellow-staining stem browns w/age, apex staying white. Often buggy.

Other Information: White pores age through pink & then flesh colors, ending a deep cocoa brown. Pores typically DNS, but may turn brownish-olive. Cap flesh DNS, or slowly turns a slate color.
