Collection location: St. Genis, France [Click for map]
Little brown jobs found in a damp mossy area in mixed hardwood forest. In the photo there seems to be leaves of alder (I didn’t really check for this at the time…). I created two collections at the time, one which was lighter in color, and one which was darker in color. They were all found within a perhaps 2 square meter area.
Looking at this under the scope.
The first microshot is of a gill edge at 400x in Meltzer’s. Here there are lots of cheilocystidia on a non-fertile margin, they are “urticoid” (in the sense of Funga Nordica), mostly with acute apecies, some with inflated apecies. Also no pleurocystidia were obs, and the spores were on 4-spored basidia.
The second microshot is of some spores at 1000x in Meltzer’s. Here the spores are lemoniform, tan, warted, and non-dextrinoid.
With these spores, these are Naucoria. I hadn’t much experience with this genus, and it was good to find (in terms of another little brown job). The spores are fairly distinctive, and the they are clearly warted, with nicely separated rounder warts. This was easy to tell as different than most Galerina, which are more “roughened” with a randomized ornamented surface to the spores.
Taking these facts and using both Funga Nordica, and Champignons de Suidde Tome 5, the keys call for something under alder (check, alder leaves in the photo, probably black alder), gills that are pale pallid when young (check), lacking universal veil fragments (check), and are pellucid striate most of the way to center at least then young (check). To check more I should make sure they have non-septate caulocystidia (didn’t check). This gets you to N. paludosa in both sources.
I seems that Naucoria and Alnicola and used interchangeably. And N. paludosa is also know as N. striatula, so I put those in.

those locales are well within our West Marin collecting circle.
So, I start poking around for red alder and I find this:
It seems someone did it for me, a click able map to recorded places where it is to be found. There seems to be recorded obs. of the tree in Inverness, Olema and Heart’s desire beach at Pt. Reyes. I should be there in a week and a half here, so that is something. I can look there.
I wouldn’t mind looking for Naucoria in Cali., and there is Red Alder on the coast, and the range is supposed to go down past Big Sur. Anyone know of good patches of Alder in the Bay Area? Or near by, like between the Bay Area and Mendocino?
