I found this in pouring rain yesterday in cattle grazed, basic unimproved grassland. Just the one snatched photo (and with an
Entoloma too , well I wasn't too keen to get my camera too wet).
I thought
Dermoloma when I turned it over, but it had an un-
Dermoloma smell, at least of the
Dermoloma I'm accustomed to, farinaceous, like a polite
Entoloma.
So I checked the cap, and it was a hymeniderm. So looking good for
Dermoloma.

Hymeniderm

Spores blue in Melzers.
Then did a gill squash in Melzer's. Spores blueing nicely so definitely amyloid. Spore sizes (6.7) 6.9-7.9 (8.6) x (3.6) 4.0-4.9 (5.0)um, Qav 1.7.
As the fungus showed no signs of reddening or blackening, it keys out to
Dermoloma pseudocuneifolium. Which is a first for me, and appears to be only the second in Yorkshire too. So I'm running it past you lot to see whether you agree with my id.
Thanks
Melanie
