It's called fly agaric. It's very common here in Germany and most of us knows this kind of mushroom. You can find it along forest paths and especially near birch woods because the fly agaric forms a symbiosis with the birch tree.

Lovely colour contrast! Nice composition! I think that if DOF was swallower it would be perfect, with a bit more backround blur. But it is very beautiful as it is as also!
