"Picked the first flush of oyster mushrooms that Bill
let me know about - made a delicious soup with parsnips, leek, and greens,
no stomach issues, so must be the right kind of fungi ;) Bet there will be
more later, but we need to remember to NOT water coffee grounds / mushrooms
with chlorinated (tap) water".
So as Bill suggests, best let Mother Nature take care of watering the mushrooms...
