These oyster mushrooms grew all up this small, doomed, oak. The mushrooms are only a symptom, not the disease. We picked as high as we could reach, but left lots to float their spores through the woods and make more mushrooms for later years. As with the Lion's mane, the heavy rains made them soggy and not as highly flavored as usual. Oyster mushrooms will appear all through the winter, spring and summer, especially after a snowy or rainy period when the temperature drops. After snows last winter they were dryer, thicker and more flavorful.
