Not an expert. It resembles some turkey tails (Trametes versicolor) I've seen in size and color. However, we need a ventral view to be certain. Being white with 3-5 mm pores would be diagnostic. A common lookalike, false turkey-tail (Stereum ostrea), has a smooth, pore-less underside. A saprophyte, key to nutrient cycling. If this is the former species, it contains several medicinal compounds.
