Today (5/26/17) while we were picking newly sprouted Meadow Mushrooms (Agaricus campestris) in the grasses of a local park, we met Jack Myers and his grandfather (they were fishing for crappie in a nearby pond.) Jack told us he had seen BIG mushrooms sprouting from a cottonwood tree's base, and took us to see. Below is a picture of Jack, Campbell (our dog), Joy, and Jack's grand father. We estimated the Oysters Mushrooms (Pleurotus ostreatus) he found weighed about 4 pounds. A very fine find, and he shared them with us. Thank you, Jack.
