Fungi

The rain is definitely getting the fungi growing. Several species today in the park. I took a few images of this one. The only problem is I don't know the species. I'm not allowed to pick them in the park, its a criminal offence. I can only go by what the photo shows. I suspect it's either a macrolepiota as it had white gills. Maybe some one will know and tell me, The cap is about 12cm across so its quite large.
