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.
Do you know the type of tree
The photo was taken back in Feb but I think that it might have been Elder.
The bark is not right for elder looks more like either Hazel,hawthorn bark it's not beech ash or oak either.
yes, you could well be right being Hawthorn,the fact that there was no leaves on the tress back then and they were growing in the hedgerows.
I have added another photo that might (or might not)help.
