This was going to go on the dune fungi thread because thats where I found it, but now I look at the image I think it possibly is on dung - I really din't notice it at the time

.
This is the only image, the larger specimens were roughly 6cm tall.
The stipe not only has verticle even grooves but have squarmules. The immature fungi seem very textured (but not granular) I have cropped the original so you can see better.
