September fungi - Pale Waxcap

I wasn't 100% sure about the ID of the Pale Waxcap that I find here every year but it has been confirmed. In fact it looked a bit different this year in terms of the cap shape but then the cap shape is always somewhat distorted. I follow Boertmann on nomenclature and he says this is a variety of Meadow Waxcap hence Hygrocybe pratensis var pallida. Others say that it is a separate species Hygrocybe berkeleyi and as a layman it certainly seems separate from the hundreds of Meadow Waxcaps I get here.
