Rather large fungus (approx 40cm long - larger than my foot!) which was probably knocked of a tree.
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.
Not sure it is G applanatum but could be one of the others. Did you take any other photos and did you feel the texture?
Thanks for the comments. New pictures added. The fungi was like hard rubber.
