Wicked Witch had a Bad Hairday?

I tried, .....welllll, maybe not vérrrrry hard, to identify this one, but to no avail! '~)

It is really completely foreign, haven't ever seen one like this!! Please help Z, or any of you, my dear Blipfriends! To be honest, I am not even sure whether one call it a mushroom or a toadstool or a champignon or whatever! :- (
