This little white Mycena is growing in masses, all over the place.

Spores 5-6.5 × 3-4 microns, inamyloid.

Note huge cystidia. Need more precise microscopy to find where exactly they come from.

I can also confirm nitrous odor, though it’s not very strong.

Checked the description and photo in Smith’s book: OK.

Thus, we almost certainly have Hemimycena delectabilis here. Thanks!
