Hi - with the weird weather patterns it appears we've had lots of Agaricus, boletes early and now lots of these guys: Boiled for ten minutes, sliced and then cooked quickly on a super-hot pan:
Xanthoderma and other phenol-containing Agaricus stain yellow that fades as its oxidised within half an hour. Yellow staining in other Agaricus (usually almond-smelling species) does not fade.
Having considered this in more detail i think daffy does little for me because i use stimulants to increase my blood pressure (which it doesnt seem to). therefore for me it was pretty useless.
We had a burst of rain and then its been super dry - so only really boletes and a few Macrolepiota clelandii up and about: Suillus granulatus Agaricus augustus:
