Stonewall - thanks! A quick search says to stay away from LBM's and that is just what I'll do. Found something about a death cap and not being able to tell it apart from other LBM's so just stay away from all of them.
def not inky. Not enough information to tell what they are. Most people would want you to rip a cap off and place half of it on white paper and the other half on black paper. That will give you a spore print which can be a valuable tool in the id process.
