it is possible to ID C. lagopus.

that this collection represents C. lagopus.
1. cap oval to elliptic at first, nearly plane post-maturity.
2. cap margin revolute in age.
3. surface of young cap covered in dense coating of white to grayish cottony fibrils.
4. young cap color grayish.
5. post-mature cap with persistent brown disc.
6. post-mature cap deeply sulcate.
7. young stipe floccose.
8. terrestrial growth on woody debris, no dung present in substate.

Sorry, I didn’t provide the necessary information one may use to eliminate all the other alleged possibilities noted in the link (see proposal). But it appears that none of the species documented in the link could be considered a reasonable match for this obs. Ones with macro-traits close to this obs, for instance C. cinereus, grow on dung. A couple of species which, by some stretch of the imagination could be considered to look like the ones in this obs, are known only to occur in the Nethertlands. Under the comments for C. lagopus (see link in proposal) the author does mention a similar species that occurs in grass and deliquesces quickly.

Although this information does raise some minimal doubt as to the identity of this obs, my confidence in using the name C. lagopus for this collection remains unchanged. Just because a group of organisms may be considered to be not well-understood is no reason to avoid using a name that fits perfectly well.
