Nothing is immortal in the 3rd dimension, except the presence of the overmind/god. Only in the forth and higher dimensions can things exists forever.

Are you sure?  rejuvenescens (asexual advantageous mutations) do not occur in fungi.

"Cloning a fruit retains the same genetic information that the original culture had and at this point it's even older."

Don't you think if the culture is older the genetic information is different? 

I agree this is true frequently, but the assertion presupposes immortally does not exist at all in fungi and a culture cannot become genitally identical and the same age or even "younger" or rejuvenated under ideal conditions after a run though a specific substrate. 



The mutation rate among eukaryotic organisms is about one in a million mitotic division. So yes. There are mutated cells in cultures but they are irrelevent at best and impossible to isolate. Keep in mind that the. Vast majority of these mutations have no obvious effect on the organism. A small percentage are potentially beneficial. Even so your odds of getting something "good" or "better" by relying on these asexual mutations is exceedingly slim. Sexual reproduction (in this case two spores fusing) is the single greatest source of genetic variability in eukaryotes, not mutation. Bacteria, on the other hand....mutate at a rate of one in 100 to 1000 binary fissions, making mutation much more revelant.

"Are you suggesting that mushrooms are immortal and self rejuvenating?"

I am suggesting it is possible "some" are. Clearly not "all" are and most strains die out when expanded exponentially over time.   

I am not suggesting to use a strain in mass without testing it.   

I do think strains degenerate at different rates not only because of their genes but also because of the substrate and fruiting conditions.

My supplier with unstable performance wasn't FP... If you are talking about my first posts with failed logs. I had a small operation called "Thyme Garden" send me a few thousand plugs a couple years ago for testing...

And it turns out the Shiitake they sent me wasn't even Shiitake... LoL! It was some type of Oyster.

Fp is the only supplier I trust at the moment, followed by Aloha. The plugs aggressively colonize Red Alder. I'm kind of uncomfortable with Aloha's statement that they don't track grain transfers... As for cultures, Aloha's I would trust as much as Fp's... If I ever get the equipment to work with cultures!

I was emailing my customer service contact at Fp and she confirmed that the Oyster sawdust spawn can likely be bulked another equal volume without any problems, but the plugs won't reliably expand any more.

Anyone know how long Oyster grain masters can be stored for? I am thinking about getting one... But, it would take me half a year to use it all! If it can't store that long, no go...
