Very small, I think the white balance is a bit off as it caught my eye as I thought it was either red paint or blood to start with!
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.
If you can go back in a few day's it would help as it may have grown more.It is fungi but at a very early stage.
I'll see what I can do, I spotted it on a couple of other stumps across the heath so hopefully I'll come across it again next week!
