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.
My id notes didn't seem to get saved - iSpot can be quite temperamental! I didn't think these were on birches, but I may be wrong, I'll look again on a future visit.
All were on dead stumps or snapped trees but in a largely coniferous part of the wood.

The bark does look like birch with a stand of conifers in the background. Best to check it though.
