Collection location: Yosemite National Park, California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

These were growing on an old log in a conifer dominant area.
The spore print was sparse but they appeared to be white and not amyloid.
The spores were approx. 5.5-6.9 X 2.5-3.4 microns and somewhat oblong.
The stipe was tough and pliant.
Couldn’t see any obvious matches in the usual references.

X. campanella indistinguishable from X. enigmatica without mating studies or DNA

Xeromphalina campanella can be distinguished from X. enigmatica only by mating studies or DNA sequencing. They’re effectively identical in macroscopic features, microscopic features, chemical features, geographic location, and substrate preference.

Re-evalution of my notes

made me realize that Xeromphalina campanella is the logical ID for these.
Initially, I ignored Xeromphalina because I did not see a clear amyloid reaction on the spores. However, the spore deposit was so sparse that a distinct color change was not possible to see and I do recall observing a faint darkening when I applied the Melzers.
