How can you mistake ANYTHING for a Morel?
FWIW, I had about two pounds of Morels grow under a pine tree in my back yard once when I lived in Seattle. Those things were amazingly delicious. I had no idea what a prize they were at the time (It was about 35 years ago).
I don’t know how you mistake Morels for other mushrooms.
All I know is that the news reports a minimum of 3 deaths each year when they hold this hunt.
