Pioppino wearing a baby mushroom as a hat (infosec.pub)

These are definitely my favourite homegrown mushroom to eat but my least favourite to grow (I just find them a little finicky). Not sure if this qualifies as a rosecomb mutation, but I did have actual rosecomb growth on subsequent fruiting from the same culture.

Any idea why you're getting mutations?

I'm not even totally sure its a mutation and there doesn't seem to be a lot of consensus on what it is or what causes it. It happens in cultivation and the wild, I believe its common to see chanterelles with this type of growth. I've tried to look it up and the reason that is stated most often is that it's due to pollutants, specifically petroleum contamination. I've never had anyone give any evidence for this, though. I do recall reading this, it states that rosecomb is the result of endogenous genetic instability but didn't want to pay to read the whole thing.
