Oyster mushrooms will grow on just about any organic plan materials, from coffee grounds to newspaper pulp. I discovered this cluster on a heap of four-year-old ground oak trees at a local park. Always consult an expert when harvesting wild mushrooms for consumption.
They are one of the best edible mushroom and are grown commercially all over the world. They get the name due to a faint taste of oysters or abalone.
I found this cluster in a local park growing on a compost heap. Unfortunately, the bugs found them before I did.
