A big help in identifying mushrooms is knowing what kind of trees they are growing near. Chanterelles normally grow near white oaks, Morels near elms, and I think the pic above is of an Ash Tree Bolote. If it is I think some folks do eat them, but not considered good eats by most (but won't kill you.) I could be totally wrong on the id and they might be deadly poisonous. (standard warning on any edible id)
Also, if that lawn has seen any kind of chemicals, don't eat mushrooms from it.
