I'm pretty sure the "Parasolspitz" is actually approx. 100m to the north-north-east:

At this location there is not even a local elevation or peak, while north of that path is a small but very prominently round little hill (larger than a mound, but very approachable).

The almost perfect sinusoidal roundness would indeed chime with the shape of the cap of the parasol mushroom, which could presumably be the namesake.
