So I did a Google image search for "poisonous mushrooms" and it gave me a picture of "Galerina marginata" from Encyclopeadia Britannica[0].

According to the app: I think it's: Psilocybe zapotecorum Or perhaps Psilocybe subtropicalis , Psathyrella piluliformis , Psathyrella longistriata , or Kuehneromyces lignicola or something totally different!

Warning!!! Many mushrooms look alike and many are toxic! Champignouf makes a lot of mistakes! Do not eat mushrooms without being sure they are edible, you could die!

Thanks, but not helpful.
