Foraging for Mushrooms this fall, I found a bunch of Oyster Mushrooms, and made this Mushroom Identification Video. Oyster Mushrooms are edible and delicious. They grow on dead or dying trees. The trees can be standing or on their side. I've found oyster mushrooms growing out of the ends of cut logs, and the stumps of dead trees.
Oyster mushrooms grow in clusters, and are usually stacked on top of each other, the individual mushrooms are kidney shape. It has gills and doesn't have much of a stem. Oyster mushrooms are white to tan colored, they are usually darker in color later in the season. The mushrooms in this video were harvested in late November.
When harvesting, I always leave some mushrooms on the tree to allow the mother plant to spread spores to create more mushrooms. So don't strip a tree of all its mushrooms, you may get a second growth of mushrooms on the same tree, so check back a week later, or after a rain.
Be sure to be very sure what you are doing when foraging for mushrooms! Learn from someone who is a practiced mushroom hunter, or consider taking a class. Do a web search for your state or county or city and "mycological society" and you may find a group offering classes. Also check nearby nature centers.
Cross check the mushrooms you find with several sources, books are best, I think. I use several books for identifying mushrooms , below are the mushroom identification books I recommend:
