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.
They do look like spangle galls, but they are in too poor a condition to identify as there are several species. They are not fungi, but galls caused by wasps in the genus Neuroterus, each wasp inducing a different shape of gall on oak-leaves.
