The close-up picture is of the surface of the gills from an unexpanded specimen with an unruptured partial veil. The surface formed by the densely packed gill-edges (especially the upper part) was covered in a layer of white hairs. I’ve played with the photo a little to make the hairs more visible.

So that is the evolutionary purpose of spore pigmentation then? Enables them to be viable after traveling farther? So brown-spored species of mushroom might be less diverse over a larger range, but more common, than white-spored species. Interesting. The white spores still travel far, but are not likely to grow when they get there if they traveled very far. Well, unless they did it by night.
Does the cap seem rather small in proportion to the stipe, and the annulus rather fragile in this specimen?
How many coastal California muscaroid samples have been studied?
Santa Cruz is a beach town in California, famous for its wild parties and amazing mushrooms. It is not an island.
“The opinion of Geml et al. is that the “cryptic” muscarioids that they identified must have been isolated from the mainland populations of muscarioid taxa for (as much as) millions of years.”
That must be quite a feat, considering how far spores can travel on the wind.
Perhaps this is one of the new undescribed muscaria species from Santa Cruz I.?
