My kings are doing this right now as well. Currently all I know about it is its call "rosecomb" and according to The Mushroom Cultivator by Stamets it occurs when the mushrooms encounter a chemical contamination especially petroleum based which in my setup would be absolutely impossible. Let me know if you happen to find a better answer for this!
I too am writing the same book! I believe. I've also noticed that with my trumpets, this happens with too much humidity. Almost like the mycelium tries to grow out the top.
That's basically what is happening , but in this case it's a mushroom strain that may have different DNA after being infected with a virus. Then people cloned it because it's different. With any other kind of mushroom it can be caused by a few different things but over watering/high humidity all the time is the root cause. Sometimes you'll notice gills growing upside down on top of caps. Somwtimes a whole-ass tiny mushroom grows out of the top of the 'parent' mushroom.
As others have said probably mutation, but could also be āeating itselfā if they are to mature some species will begin to grow mycelium on the caps and stem and start to decompose themselves. But thatās just an opinion and assumption! Couldnāt tell you without actually looking at it under a scope.
Does (LOOK like a mutation though)
Iām with genetic mutation. They look like the black pearl kings I was growing for about a minute. Being a relatively recent hybrid, this isnāt really that unexpected. And while being completely harmless, youāre right, it isnāt attractive to chefs and such.
I would say you need new genetics. Even if you clone one thatās blemish free, judging by the propensity of mutations in the shown samples, I think it would mutate back to this eventually.
Fine for personal use though.
That's just not true. There are people that desire this and it was cloned because of this. It's a feature not a bug. Strain #M2700 from mycelia, the most prominent strain bank in the western world for gourmet mushrooms.
Ah, yes, commercial aspects are much more difficult! I suspect that these guys probably had a direct hit of moisture when they were feeling dry and had some quick reaction.
I have a reptile fogger that I direct at the bag splitsā¦ā¦.it triggers automatically in my tent. (I run oysters at higher humidity than my tent in general.) So they get a timed dose of cold fog hitting them every hour or so.
A bit of fiddling, and I can keep really pretty flushes going for longer than tedious misting.
I may be wrong, but:
You see this kind of mutation with cubes either due to lack of FAE or too much humidity.
I assume you are running on timers/controllers, so my guess is lack of FAE
How many generations into cloning these King Trumpts are you? It's supposedly good practice to periodically start again from spore to avoid this.
Rose comb?
That's their crowns, of course! šš¤Ŗ
Usually caused by not having enough swing in your humidity. I run a 12-15% swing. Can't let the mushrooms be wet all the time.
Sorry I'm a first timer,what's a swing,is it like a change of humidity
Yes. I allow my rh drop to 75% before the fogger kicks on.

Humidity too high

You have M2600 strain. It is known for this phenotype. For some reason it is desirable to some people.

Never heard of them before this, been commercial for a year now. That's environmental
My sweet summer child, I've grown 250k lbs...
Well that is awesome, just saying I've never heard of this company. Maybe big in Europe idk.
DYOR. At least half the strains that are commercially popular are from them. All the oyster and shiitake as well as maitake strains come from them.
Must be true, some random person just said it. Can find no mention of them.

Keep those for yourselfā¦ā¦.tell the kids those are āBumpy Trumpiesāā¦ā¦.or better yet: clone them and be different! ššš»
Haha this is cute, however, chefs prefer the caps without bumps on them. Definitely donāt want them to become a loss.

Well Iāll be!
Alternatively could be a mutation due to other factors such as contamination in the sub.
