A bit off topic, but I have done some tests in the past that resulted in the Cubensis on agar link in my signature below.
This is, in theory, genetics from spores and media (substrate) adaption, birthed on wood.
----
First I picked up some spores using the fine end of 1/2 a sterilized wooden toothpick (quickly flamed over) and a foil print, using sterilized metal tweezers (being fully aseptic).
I placed the spores into enriched paper pellets (my normal WL-Tek recipe), but also knew cellulose is very complex (decays slowly also).
I added a few drops of sucrose water (sugars, sterilized) down the peg and the surrounding area using a syringe.
It took roughly 5-6 days to germinate and grow out, which I then transferred to a used black tea bag (no real sugars).
See my signature so see white-rot after transfer 2 using black tea extracts (as if making tea) + agar.
Some transfer 1 images (peg removed).
----
Note, black tea bags are human grade (even the cheap ones, interestingly), although I wouldn't eat them, lol.
High in nitrogen (mostly proteins), and mostly complex carbohydrates (cellulose) + phenols.
Frida - Food ID: 537 (fooddata.dk) < Per 100g, approx up to 3.1% nitrogen (not sure which stage of oxidation).
