After reading through this thread, on the first page, the following comment caught my attention: "Secondly, as microbe keenly points out, one can even see the chemical signals sent by the mycelium on the agar surface."
I recently knocked up a bunch of multi-spore Penis Envy cakes and noticed that every jar would quickly cast out a very light 'pre-mycelium' layer. After covering 85-90% of the jar, the myc would start to consolidate out from the inoculation points and into the thick rhizomatic mycelium that I'm used to seeing.
Initially I thought something was off, perhaps even cobweb, but they colonized 100% and fruited pretty decently: https://mycotopia.ne...1-no-roll-mspe/
I've never seen this 'pre-myc' with any other cube, TPB, B+, etc., and I'm wondering if these are the 'chemical signals sent by the mycelium' that you mentioned.
I isolated 3 different dominant sub-strains with the same PE spores, via Fahtster's Mycelium Syringe Tek, https://mycotopia.ne...ge-tek-revised/
I've noticed that only one of the isolates continue to present the same 'pre-myc' phenomenon, while the other 2 immediately colonize jars with the thick white myc I'm accustomed to.
Any idea what this is? Is there a specific term for this phenomenon? Can chemical signals stretch out over 90% of a jar before inoculation points even begin to consolidate? Would the reason that one of the isolates still exhibit this behavior be due to the fact that it's not truly an isolate?
Sorry for all the questions Cat, but I figured you'd probably know.
Aside from colonizing a little more slowly, it's not causing any grief, I'm just terribly curious lol.
