I found the ones this year around dead elm an tulip tree They were the gyromitra but have found verpas around tulip mostly they are a little harder for some to tell but the stem has a cotton fiber and the main part of the shroom is not pitted it looks wavy. Some say they eat them but I won't nor would never recommend it! As far as soil I guess I never really paid attention but the 3 trees I have seen false ones are elm, ash and tulip!
