Each one is no bigger than a couple inches.
For better results with mushroom identification in the future, try to get photos of the underside and stipe of mushrooms. The more pics the better chances of ID. Providing a rough location can also be beneficial. From what I can tell this mushroom is likely some type of oyster mushroom (Pleurotus sp) or maybe a flat crep (Crepidotus applanatus)
