Found in local pasture/grass field were we locals walk our dogs.
This fungi first appeared about 5 days previous, this image is of the second flush.
The first image is a young specimen, newly emerged
Whilst the second image shows the remains of the first flush
I seem to have missed the intermediate stage, but will be watching out for it now.

Did wonder if it was a Macrolepiota sp. - but then I've been wrong before.
Looking forward to your suggestions
