Checked on the development of some of the fungi and photographed the change and also added a couple of new ones.
Still haven't got this one identified but maybe when it opens up more I will have a better chance.
Another False Parasol emerged nearby the dinner plate one but I don't think it will be as big.
There were a few of these quite close together and I thought they looked like field mushrooms but I had to pick one to check the gills.
Matches the description listed for Agaricus campestis, Field Mushroom.
