contamination of edible mushrooms?

[SELKIRKS]

Hmmmm....  First, before I ever eat an edible, I am always 100% positive
in my identification.  I mention this to you because you state, "I have
what ***appear*** to be Coprinus micaceous..."  Secondly, there are enough
edibles out and about in pristine places that if I even suspect that
something as possibly being contaminated, I don't risk it.  Try taking
pictures instead...
