Mushroom!

18°C  -  8 mph ESE  Wind Speed  -  14 mph Gusts  -  Cloudy  -  Sunny Intervals.  Found this Mushroom growing amongst the grass in my Wild Garden this morning.  It is very large  -  about 6 inches across and standing about 8 inches high.  I’ve spent ages online trying to identify it without success.  I’ve added a view of its Gills to the Extra.
