Mycena Zephirus

I think this is a mycena zephirus (the Latin name is also the English one), but since I neither took one out of the ground to study its roots nor cut into one to discover the color of its sap and there are about a dozen-dozen ‘shrooms in the mycena family and for some of them these things are the final dividing characteristics, it might also be some other kind of Helmling. An Helmling it is, that much I think I can say for certain. Not toxic, but considered inedible – and apparently tastes strongly of radish.
