Ascomycetes – Morchella – The true Morels vs the False Morels
If I told you where these were, I would have to shoot you! They are a spring mushroom, and highly prized. We also encountered some false Morels, which are poison. I’m grateful that I have my Dad’s mushroom books to help me identify them.
