Does this look like
Conocybe siliginea? There is a dearth of photographs of it on the net. Found in unimproved grassland, sheep pasture.
The cap is distinctively wrinkled. Spores were big, a few were 20-25.5um, though the majority were in the range 14.1-17.1 x 7.8-9.3um, Qav = 1.8. Cheilocystidia skittle shaped, caulocystidia also mainly skittle shaped.

caulocystidia.
I'm not sure whether the basidia were 2 or 4 spored as I didn't find any with spores attacked or recently departed
. Caulo cystidia were generally skittle shaped and found near the stipe apex and midway down the stipe.
