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.
Did it have pores? and what was the colour of the stem?
I can't get an idea of scale from this photo, but it looks to me like Jelly Ear/A.auricula-judae. They can grow pretty big sometimes and don't always form a cupped shape.
That was exactly my thought.
I've added an ID revision.
