Notes: Caps up to 3.5 cm across.
Spores ~ 13.1-15.9 X 6.0-7.0 microns.
The spores were distinctly rocket shaped with few basal nodules.
I wanted to call them I. sierraensis but what few gill cystidia I could find, they were thick-walled and ~ 50 X 16-19 microns.
These almost seem to be a cross between the two species.

Thanks for posting.
Looks to be a good match to Inocybe chelanensis with those rocket-shaped spores and thick walled cystidia.
From the Bradley Kropp and Brandon Matheny paper, “Basidiospore homoplasy and variation in the Inocybe chelanensis group in North America,” Mycologia, March/April 2004:
“Basidiospores (10.0–)11.0–14.1–17.0(–19.5) × (4.5–)5.0–5.7–6.5 (–7.5) μm, mostly rocket shaped in outline with 2–4 basal nodules and an elongated apex, some are nearly smooth in outline or have an elongated triangular outline, occasional spores vary in outline from the typical rocket shape by having one or two lateral nodules, rarely quite polymorphic; spore color yellowish under the microscope (2.5Y 9/4, 8.5/6, 8.5/4, 8.5/2). Basidia 25–47 × 8–14 μm, clavate, mostly 4-spored. Pleurocystidia 41–81 × 25–12 μm, slightly thick-walled to thick-walled, walls 1.0–2.5 μm thick, pale yellowish, fusiform-ventricose, sometimes narrowly so, occasionally ovate, usually above a short pedicel, apices obtuse and crystalliferous. Cheilocystidia 29–85 × 10–27 μm, similar to pleurocystidia, no paracystidia observed.”
