From your picture, this belongs to the broad-pleated mushroom. It is not recommended to eat wild mushrooms of unknown origin.

The broad-pleated mushroom fruiting bodies are solitary or clustered. The cap is 5-12Cm in diameter, flat hemispherical to spreading, sometimes the edge turns upward after old age, gray-white to gray-brown, water-immersed when wet, smooth with dark fine stripes, and the edge is often cracked after maturity.
