Observation 63222: Ramaria rubricarnata var. verna R.H. Petersen & Scates
When: 2011-01-16
Herbarium specimen reported

Notes: Found under live oak.

Haven’t seen a Ramaria here for many years, and this time a big group of them. Going with id with the pinkish orange branches and the bright yellow tips, and the large conjoined base.

The first micro-shot is of a branch end at 1000x in KOH. The basidia here are clamped. Ok, not the best shot, but it is there, if I get to it, I should circle the clamped basidia.

The second micro-shot is of spores from the branch at 1000x in KOH. The spores are long, cylidrical, with a rounded end, and warted. The measured average size of the spores is length – 11.67 +/- 0.78 (err 0.30) um, width – 4.58 +/- 0.23 um (err: 0.12) – q : 2.55 +/- 0.11, on 7 spores.

This was the first time I saw the clamp con. on the basidia for a Ramaria. Once I could see it, it wasn’t hard. But usually with Ramaria the basidia stay all tightly clumped no matter how hard I squash it. The problem isn’t seeing the clamps, as much as it seems to be the ability to easily separate the basidia in the mount. But with the clamps, and the colors, and esp. the width of the spores, as only 4.6 um, this comes out at Ramaria rubricarnata var. verna in the Pacific NW Ramaria book. The only problem is in the season, since this is winter here, and the species is supposed to be seen in spring. And the habitat, where it is under pines in the Pacific NW, and is under live oaks here.
But everything else matches exactly, so I’m going with the id.
