Janie,
You are correct. What I call field mushroom, is in fact the meadow mushroom. About four years ago I couldn't beleive my eyes when I looked across the road to a field that had just been harvest of it's corn. The field (and I'm speaking of acres.) was white. I picked buckets and buckets of them. I have tried different methods of storing them but none to my satisfaction. If anyone has had success in storing them please share your recipe.
