A giant mushroom

Coming out of a nearly vertical old dune wall. The stem is nearly 5 cm in diameter, the top that I wanted to put in an extra was looking like a beige-white breakfast plate. ( but I think I don’t have anymore extras). As it got older the plate frizzled out at the edges and the center sunk deeper so it looks like a whitish star bowl from the other side.
A little forest walk, not as far as the day before. Am very tired out by the pains in my body...
