I was pulling the stems out of some mushroom caps today - we save the stems and make broth out of them - when I discovered that some stems weren't coming out all the way. Have a look:
Mushroom fanatics out there: Any idea what causes this? Is there something wrong with these mushrooms? Am I being paranoid because I just read this question?
Mushrooms are complicated little guys. What you see as a single type of mushrooms is actually hundreds of different substrains. Its possible they're from a slightly different batch than what you're used to, and so have slightly different stems. I wouldn't worry about it, and enjoy the mushrooms!
Jefromi's comment is spot on. I wouldn't be paranoid. The stem probably just didn't feel like coming out and hung on the head. This is completely normal and unless you picked these mushrooms yourself, I would never worry about that.
