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.
I agree that C gambosa is the most likely but without more detail it would be imposible to be sure.
Sadly my local StGM rings have been very poor on account of the dry weather.
I am planning to return in the next few days what other information should I look for to be able to be able to confirm it as St George's Mushroom.
