How to describe this magnificent fungi. It sprouts up from the spiky, redwood leaf litter on a smooth, cream colored stalk - maybe 10-15cm tall (but what do I know as an American 🙄). What was last night a tall, domed cap the same color as the stem transformed overnight into a disk shape ringed with shiny, almost metallic black fronds that curl under. Other gray mushroom anatomy going on inside the ring.

Macro shot of a mushroom growing on moss. The cap is bent in such a way that it perfectly presents its gills to the viewer. The focus is on the nearest part of its gills.
