These are some older photos of what I believe is Hericium cirratum, a species related to Hericium erinaceus (otherwise known as Lion’s Mane Mushroom).

Apparently this mushroom is rather rare where I am (Central England).

The older mycologists I’d informed of the location had told me not to share the location online as apparently this mushroom is very popular for poaching.

Still one of the most unique mushrooms I’ve encountered
