Psilocybin and mycelium

So when on a bit of a hunt today and found the best looking Psilocybe subaeruginosa specimens i have seen this season! What i found really interesting was that a majority of these specimens had significant bluing on the base of stem up from where it connects to ground/mycelium (refer to picture). Does this suggest that psilocybin may be produced in the mycelium and contains a higher concentration of psilocybin then the fruiting body? If that is the case I’m curious as to what role psilocybin plays within the mycelium Or may this have been a result of other factors? Anyone with some mycology knowledge care to share there expertises on this topic

The mycelium of Psilocybe spp. apparently produces and contains psilocybin/psilocin. This is quite evident when looking at people growing P. cubensis for instance, that the "cakes" will sometimes bruise blue, even prior to fruiting.
I have no idea how high the concentration might be, but given the nature of mycelial hyphae, I'd assume that even if it contains similar percentage levels as the fruit bodies one would need large amounts of mycelium to get on par with the alkaloid contents of even only a single fruit body.
To state it in a simpler way - how many grams of fruit bodies could one single gram of mycelium potentially produce?

Thats very interesting! Then i wonder what role psilocybin/psilocin plays in the mycelium, because it can be inferred that it is not produced there to act as a toxin to prevent consumption (although i could be wrong).

The tryptamines contained are not considered toxic. I know little about the production process, but remember reading that it somehow involves the amino acid tryptophan. As to why the indoles are produced, that is a question still unanswered, to my knowledge. Why do, for example, many Panaeolus contain serotonin?
Similarly, why do toxic mushrooms produce toxins? It is probably not to poison people, or protect itself from predators - eventually, the fungal organism isn't harmed by anyone eating the fruitbodies. I have read studies on Cortinarius rubellus that suggest the toxins contained are results of the fungal organisms metabolisation of other toxins contained in the substrate, thus it helps "cleaning" the habitat of certain damaging chemicals, almost like they were "kidneys" working in the eco system.
