Looks like a cat's ear. (I thought it would be a good idea to shoot on white paper. I was wrong!)
About 100 mm in height.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
you need to put the full title on Helvella crispa then I can agree,lovely find
I was slightly cautious because the one in my Roger's is slightly darker at the top whereas mine is all white.
never go on the photo as there not always spot on but in the description of the fungi it does say that it is white.
