alright, I have some pics of these, but not with me at the moment. i'll do my best in describing them. i live in central texas on a farm where we have cattle. the cattle mainly graze other than the occasional little pellet treat. the mushrooms i'm finding are growing directly in the dung. the dung is usually dried, almost compost like. the mushrooms grow in little groups, but not clustered thouroughly. they are fairly tall (3"), the caps are an off white, and are usually dome shaped...nearly hemispherical. they are extremely sticky/moist when young. the gills are dark colored/brown/grey by the time the sun comes out, otherwise they are a reddish white/brown. the gills become ashy with age. the stem in slender, and tubular...kind of fibrous. there is no bluing/bruising when handled. when matured, the caps flatten out slightly and the middle changes to a little darker shade of the cap's original color (almost pearl/vanilla colored). i'll post some pics soon, but for now - anyone want to take a stab at it?
