I would call them scales, Jacob.

I’m sure they are part of the mushroom. They are on 3 of the older specimens in your photos. I see them all over the mushroom: top, bottom, and sides of the cap.

The cone is pine. The uneven distribution of scales could be accounted for by several variables: insects, scraping against cone scales while maturing, etc.

Regarding point 4: “not a single Lactocolybia fb that I’ve seen on MO or Google images has cap stuff,” you may have a new species here, Jacob. Important to collect a voucher collection for future reference.

Thank you! I’d forgotten to make a comment about that.

I don’t think the granules (?) are part of the mushroom. I think they’re part of the scattered layer of exogenous icky moldy crumbly white-to-yellow stuff around this patch. Chemical residue? Fungal? Bacterial?

It is admittedly weird to suggest that a ring of cap “tissue” isn’t part of the mushroom, but (a) there was lots of that stuff on the cone where the fb’s were growing, (b) it looks a little uneven/random, © the correspondence to the cap margin can be explained by symmetrical cap growth after a pin had been covered by it, and (d) not a single Lactocollybia fb that I’ve seen on MO or Google images has cap stuff.

What do you think?

In photos 3 and 4

great capture of the tiny scales on the rim of the cap, Jacob.
