I saw a good sized clump of A. Xanthoderma on Saturday in E. Sussex
but only the one clump, despite seeing a lot of other fungi,
including Hydnum Repandum v. Rufescens and Clitopilus Prunulus
for the first time in edible quantities. (The latter is really rather
tasty). I should go and have a
look in Hyde Park which has a number of patches growing A. Xanthoderma.

Like you I have never dared try them. I met someone once who
inadvertently got some into the frying pan, but apparently they
tasted 'inky' so they didn't actually eat more than a mouthful.

Wish I knew. They don't seem to like fruiting in the rain - if anything
they come up just before rain is due, but fungi don't seem to like
doing anything 'normal'. I have even seen Lepista Nuda in April!
