Edit: After a bit of research and asking around, it seems that this is likely Cystolepiota bucknallii

Hi! I came across this strange little thing last week and have been struggling to ID it. I’m hoping that maybe someone here can help.

It was found growing in the soil of a mixed forrest, lots of birch, elder, and larch, 10km or so north of the German alps.

Maybe the photo isn’t super clear, but the stem is not hollow. And one very distinct feature is that it stank like gasoline or hot plastic. The smell was strong and lingered on my hands long after handling it.

Thank you!
