This is Joshua Birkebak’s new Ramariopsis bensoniae.

Irene, thanks again. I’m going to preserve the little things for someone who may know or find out.

I had the same thoughts about kunzei as you, not being used to see it on wood, and it looked very small and delicate compared to the mycenas.
But the spores leads to Ramariopsis, and var. favreae seemed to me like the best match in that key. Perhaps there are more species or varieties to find in some newer literature..

Irene, thanks a lot for looking at this fungus, and for the reference. It looks like there is more microscopy to do here. They measure everything!

“Branches …, very crowded, caespitose at the base when the stem portion is virtually absent” — we don’t have this. And the spores, I don’t know if they being consistently round is a strong feature.

differs from the main variety by its smaller size, growth on wood, slightly larger spores (looks like they can be quite variable), discolouring stem base and slightly flattened branches.
Described in Mycologia 61(3), p. 556.
What do you think?

Can it be kunzei?

(1) Our spores are not “broadly elliptic to round”, but round without exception.

(2) Assuming our specimens are mature, they’re too small for kunzei.

(3) Kunzei is (mostly) terrestrial.
