You may want to join a mushroom club. I see your in Mercer and you might not be to far from this club, Western Pa. Mushroom Club-www.wpamushroomclub.org . I think ikt costa about $15.00 year for membership, money well spent. They have meeting, mushroom cooking demostrations and eating, and most important they go out on forays with seasoned mushroom pickers who show you whats what. We'll soon be heading into prime mushroom picking time. I have a small library of shroom books I've studied over the years and still only pick ones I'm 100% sure of.
