Found a group of these in Dartington Hall gardens – not sure how to upload picture.
Hi Dave, you can send them to us here https://www.wildfooduk.com/contact-us/ or via email to [email protected]
An enormous patch of them still looking good in Dartington Hall. Rather an unusual location as these are normally associated with alkaline substrates and usually but not exclusively with beech. These are almost certainly associated with yew.
found these at pressmenan lake _MG_2790.jpg
