Just found my first couple of Half Frees last weekend. Really small and fragile. I cut them in half to help ID them, and I believe 2 of the 3 were half free and the other possibly a Verpa. The caps were all so small that I couldn't determine the connection point to the stem so I didn't feel comfortable giving them a 100% ID'd. Versus edible morels, I wouldn't describe them as "common" (3 vs. 350 last weekend), but certainly not impossible. if many were found and positively ID'd, I'd give them a taste, but they are so small and delicate you'd need a ton of them to make anything with.
