For some people maybe. What I heard on Strange ER episodes is that almost all mushrooms have a poisonous relative that looks quite similar.
I also seem to remember some conversations that my Dad had with others regarding being careful collecting them, if they had no prior experience.
However, I have no first hand experience myself.
There is only one other that looks somewhat similar to the morel but is actually easily distinguished. The morel is attached to it’s base all around the bottom. The others are attached up inside the cap only.
There is a mushroom known as the False Morel. Here’s a website with comparisons: http://www.michiganmorels.com/morels2.shtml
