Evening Glory said:May be P. semilanceata, but I doubt it. The pictures are too blurry to give a definitive ID, but my guess would be Conocybe apala syn. Conocybe lactea. The mushrooms seems to lack the distinctive nipple P. semilanceata have, and they also seem to be white rather than yellow to brown.
Look for blue bruising and take a look at the color of the gills. P. semilanceata have purple-brown gills and spores. Conocybe apala has reddish brown gills and spores.
