Great Mushroom Expansion

[Kaios]

Nice idea, I now expect to be able to grow a mushroom house some day.

Me too. In real life They have begun producing a packaging substitute for styrofoam from baked mycelium. Houses when?

I was hoping we might get philosophers stones occasionally instead of truffles. Not sure what potential use psilocybin could offer. Increase in learning speed perhaps?

based on my experiences, i'd have to say a big buff to psyche would be the most realistic, maybe along with a big hit to dex. you could also have it as a 100% occuring lore event -

high on mushrooms: What did you just eat? The Hearthlands have become much more colourful!

to give a guaranteed bit of XP like the dreams in the beaver dungeons.

Along with only being able to move at crawl speed and being distracted by completely ordinary objects like a tree or shrub, moving over to investigate whether you want to or not every few minutes.
