will a strain repeatedly cloned lose its vigor?

A question about the process of cloning an isolated strain with mycelia... I have found a variant amoung a group of 14 jars which were all inocculated with the same Gulf Coast print from Homestead. The mycelia in this one jar produces mushrooms totally unlike what the others produced. They are fat, tall, potent, and twisted looking. I managed to inocculate more jars with mycelia from this strain (it wasn't really a "sterile" technique, but it seemed to work) and plan to case some of them but use some of them as "clone jars" so I can continue to keep this strain growing. I know taking a spore print will not mean the resulting mycelia will in fact be identical to the "parent" mushroom. Cloning with mycelia seems to work, I was just wondering if the strain will lose its vigor if it is used continuously. I know you can clone with tissue, but why would that be any different than with a pure strain of mycelia?

Yes it can lose it's vigor P. Stamets uses the p. value system mean the he only transfer mycelium 10 time from agar to agar--If you use a different substrate each time you will do o.k. finch seed then rye grain then wheat grain etc...

Would there be any way to breed a specific clone back to its parent mycelium to stabilize the strain?

Just keep those 'clone jars' in the refrigerator. Only take them out when you need to do a grain to grain transfer. They should last for a year or two that way, then simply do a g2g and keep one of those jars back as a strain master. RR

You can store G-1 LC in 5, 50 or 100 vials of sterile water (years & years).
Any time you want G-1 pull a tube out of the Fridge & go for it.
Either start a new LC with it, or go to grains, then G2G.

agar- just put a few cc of LC into a vial of sterile water?

You put the LC solution in a rubber stoppered tube.
Allow the myc to settle to the bottom.

You then aspirate out the solution, leaving the myc in the bottom.
(that removes most nutrients).
You then inject sterile water into the tube.

Then refrigerate that tube.
It will remain viable for years.

Agar- How do you aspirate out the solution without risk of infections?

Soak a few cottom balls in alcohol. Swab down the surface of what you asperate out of, or inject into. Keep the needle wrapped in that alc soaked cotton ball, so it is not exposed to open air.

I would recommend asperating through the rubber cap. Just inject the air and suck in succession until the free liquid is out. Removing the rubber cap is asking for trouble unless you have a glove box or flow hood.

Buffer the medium at various pH values. This causes many mycelia morphologies to differentiate. A clone from a single pure plate to plates of differing pH will all exhibit different growth morphologies.
