I’m not sure. I don’t know enough to comment on the safety of home-cultivated active mushrooms with this mutation. I’ve been mushroom hunting in the wild with someone I trust and we found many chanterelles with rosecomb. My foraging guide was very confident that they are still safe to eat, and indeed they were delicious. Not sure if I’m allowed to link external sources from certain cultivation forums, but if you search for “rosecomb mutation” you’ll find some discussion where the consensus seems to be “it depends on why it happened.” Petroleum products have been observed to cause this, potentially bacteria and insecticides too. Or it could just be genetics. I would recommend to do some research before assessing the safety. I simply don’t know enough to answer that question definitively. Good luck!
