At first sight I thought this might be Mycena pura, but the spores are at odds with this. I’ve attached images of the same spores taken at three levels, and these suggest small warts or spines. The images of basidia seem to indicate they are 2-spored rather than 4-spored, but that might be my misunderstanding of the images. (Sorry the images are not as sharp as I’d like.)
Help please! This seems to be cross between a Mycena and a Laccaria!
