I found this out in the forest on a nature walk. It has a beautiful bright white colour with a fan shaped cap with a wavy cap margin. It has a smooth cap surface with pretty much no stem. Its gills are crowded, narrow the edges looked eroded. and its hard to tell the attachment of the gills from the photo. I think this might be a Pleurocybella porrigens which I found on the mushroom up tab. I think one common name for it is angel wings
