Biology behind mycelial "consolidation"?
    #6856211 -

Had no luck with search feature. Apologies if it's easily available somewhere here....

Can someone please point me to some information about the biology involved in the "consolidation" of mycelium before fruiting? If I had to guess, I would say maybe consolidation is the period when the fruiting mycelium need to somehow network together to have the necessary energy or whatever necessary to form a fruit--I would guess a tiny tiny piece of mycelium that is genetically predisposed to fruiting wouldn't even be able to muster a tiny fruiting body by itself. So what actually explains this period during which fruiting cannot be triggered?

Any good resources about the biology of mycelium in general are appreciated too. Thanks.

Colonization period? Keep in dark. Expose to light when u want fruiting to start. Good ? with how much area is needed to fruit.?

There is no reason to keep colonizing mycelium in the dark. Normal room light has no effect on anything during the colonization phase. I've proved that by many years of colonizing jars at room temperature and exposed to normal room lighting from the day of inoculation.

Consolidation is the part of the process where the mycelium has finished 'colonizing' the substrate, but has not had had time to digest enough of the food to be able to fruit readily. This is the reason for leaving brf in the jars for a week past full colonization. If you birth right away at full colonization, they won't fruit for a week anyway, so may as well leave them in the jars during that time so they're not drying out.

The above assumes that your jars colonized very fast in a properly prepared substrate that remained contaminant free. Obviously if the jars took two months to colonize, and/or there's bacteria in the jars, they could even start fruiting invitro prior to full colonization.

Stamets also explains the idea of consolidation in his books. It's not necessary with grains if you're going to be spawning to bulk or using for grain to grain transfers, but you do need to wait for full colonization. However, with pf cakes and other bulk substrates, it helps to wait some time after full colonization before initiating fruiting conditions. Doing so results in more prolific flushes. Failure to do so with some of the harder to grow edibles such as P nameko and Shiitake sometimes results in no flush at all.

WOW, i am always wrong somewhere, SORRY RR. I thought they needed dark for "better" colonization. Well that adds to the.."You learn something new everyday" Just trying to help people out. but always mis-inform. Guess i get mis-informed from all the bogus info out there. If there is one thing i KNOW, listen to RR.

Thanks for the primer on consolidation.

Re: Keeping colonizing mycelium in the dark: Is there any reason, then, why frequent jar checks [assuming PF] would be detrimental? Assuming enough of a dry, fine-grain verm barrier, is contamination possibility really increased by examining jars frequently?

When you examine them, don't turn them upside down. That can cause the verm barrier to shift. You can expect there to be contaminant spores near the air/inoculation holes, and if you shift the jar around, those mold spores can be shifted down and into the substrate, contaminating it.

Below is a picture of one of my colonization shelves. As you can see, quarts of rye, 1/2 pint brf jars, and filter patch bags all share a spot in the open air at normal room temperature and normal indoor lighting. There is one time that darkness can be used to your advantage, and that is after applying a casing layer. Cover the colonizing casing layer with foil to keep CO2 levels high and also to keep light off. This way, when you remove the foil, you introduce all the pinning triggers of full colonization, air exchange, light, drop in CO2 levels, and evaporation of moisture from the substrate at the same time. This can trigger massive pinsets. However, during the colonization phase, light is irrelevant.

I wish he'd use some more wide-mouth, tapered half-pint Ball jars.  They were just discontinued due to low demand. :frown:


RR:  That shelving unit looks cool.  It's modular and you can add as many shelves as you want?  Could you let me know who makes it?

Edit:  D'oh... memory finally kicked in, looks like Rubbermaid.

It's rubbermaid, and I bought two of them, then cut the posts between them to make them shorter. They were 24" between shelves, but I cut that in half to get more jars into the same space.
