but no spore print, right?

I was curious as to the color, since there seems to be quite a disparity in various descriptions (see Matchmaker), which makes me wonder if there are not some cryptic species involved.

Otherwise, the macro certainly did indicate Deconica horizontalis, and now the micro as well.

As stated prior, nice find, Deb!

Spores 6 – 7 × 4 micrometers, smooth, with a germ pore. A good match for Deconica horizontalis.

Rehumidify them

Often you can get a dry cap to drop spores by adding a drop of water on top of the cap and covering with a small cup. Moisten the inside surface of the cup first. The enclosed air gains humidity and the gills hydrate enough to release spores.

Thanks! My specimens are too dry for a good spore print.

If I get fresh ones I’ll try. Sometime I’ll scope them.

is it really possible

that this is the exact same species all across the world?
it purportedly occurs from the PNW to Berkeley to Santa Cruz to Mexico to South America to Europe and waaaaaaay over to Australia!

got spore print on these? I would love to see it!

nice find, and it has gone thru quite a few name changes recently.
if you have Matchmaker (a free download), you can look up the details.
See “Melanotus horizontalis” in the gilled mushroom section.
