I didn't realize that your references to only eating hollow stemmed mushrooms, etc. were only directed to the Morel family. You are correct, as all true Morels are hollow stemmen, non wavey, and or course, not all are black. I thought you were referring to mushrooms in general. My apologies sir.

About 5 years ago I was fishing in Western Ontario in late spring, and one of the guides brought back to camp about 5 pounds of what he thought were Morels. The were, in fact, a false Morel, as all of the stems had a kind of cottony substance in them. I'm glad I was there to set things straight, as there could have been quite a few sick people in camp that night.
