Managed to get a 2nd harvest of Black King oyster #mushrooms after all! They started off pretty gnarly, then became little bowling pins with hats before filling out into standard mushrooms. I probably should've harvested them yesterday before they flipped up, but ah well. They're nowhere near as messy as some of the other oyster varieties when they drop their spores. Still got some nubbins on the block, so not composting it just yet...
