Guys,
Thank you for writing me back.
It is round, approximately 2.5 cm in diameter, and when I poked it, a red liquid came out of it. The shell is hard, and has a series of reddish veins running along the outside. The skin is brown. I found it unattached on the ground.
I looked through books, and did a mushroom identification, but couldn't find anything that matched it.
Thanks,
Chris
