Possibly a Russula xerampalina. It is extremely variable in color. I have seen it in red, wine, tannish, and even greenish. Before looking at the actual fungus, I thought it may be Cortinarius iodes. http://mushroomobserver.org/observer/observation_search?pattern=russula+xerampelinahttp://mushroomobserver.org/observer/observation_search?pattern=cortinarius+iodes
Neat 'shroom. Oddly enough after I saw it here it also appeared in the AT Journey's magazine that I get. Very cool!
Almost definitely a Russula xerampalina. The other species, Russula brunneoviolacea, is the only other contender for this photo in my mind, but it doesn't usually show a pitted cap. Did it smell like shrimp? Did the stem break like a piece of chalk?
