I'm not 100% sure what the real answers are, only what I think and some data I am working with. Regardless, more on oxygen, but now with golden oyster.
Here I made a WL-Tek block (paper + MG soluble nutrients) with grain spawn, and compared the same block, indoors and outdoors.
The indoor setup had good FAE, you might say lots, but in fact it's medium, and outdoors I got max FAE.
When KO is grown in low O2 conditions, it fattens up, but produces less colour-other.

Reactive oxygen species and antioxidant properties from mushrooms - Has illustrations.
Oxidative stress in industrial fungi - Short version, no illustrations.
Extract from my journal, to help understand active materials (antioxidants):
"Psilocybin is a tryptamine compound with a chemical structure containing an indole ring linked to an ethylamine substituent. It is chemically related to the amino acid tryptophan, and is structurally similar to serotonin."
"Psilocybin is a member of the tryptophan-based compounds that originally functioned as antioxidants in earlier life forms before assuming more complex functions in multicellular organisms."
"Psilocin is relatively unstable in solution due to its phenolic hydroxy (-OH) group. In the presence of oxygen it readily forms bluish and dark black degradation products"
"Most species of psilocybin-containing mushrooms bruise blue when handled or damaged due to the oxidization of phenolic compounds"
Nor-baeocystin are analogs of psilocybin, meaning single or various elements are added or removed.
It appears they can be phosphorylated or dephosphorylated (cleaved, added, a cycle?).
All four compounds contain carbon, hydrogen, nitrogen and oxygen.
Note, the most potent mushrooms usually produce little mass (thin, small, hollow) and can be wood loving (lignicolous).
Phenols require oxygen and oxygen radicals to decay properly, In my mind this is relative to above.
Antioxidants could be considered like wearing gloves to use a hot oven (cooks food).
