Okay, here’s the macro:
Pileus medium ochre brown at the center with an orangey wash outwards to lighter straw-colored away from the disc, radially fibrous, splitting. Not rivulose, but perhaps could be called rimose.
Lamellae: Dingy medium-light brown.
Stipe: Striate, glabrous except for at highest part of apex and near the very base. Base slightly bulbed, weakly rimmed. Mostly pallid beige to flesh colored, but with some weak pinkish near the base, and two small, distinct rose colored blotches.
Spores ellipsoid-amygdaliform? citriform? (not sure what these would be judged), thin walls, smooth, minutely roughened. Some with 1 or 2 apparent “depressions”.
L/W avg: 9.4 × 5.3 μm.
Metuloids / Cystidia: Utriform, with smallish crystals, thick-walled. ~ 60 microns long, walls up to 5 microns thick.
Caulocystidia at apex: Utriform, crystals not present (?) or obscure, some clavate-ventricose, with interspersed filiform cystidia. Clamps observed in hyphae of context at stipe apex.
Caulocystidia at base: More similar to lamellar metuloids (odd…) Perhaps with less thickened walls, and with smallish, sometimes erect crystals. Tufted, and with clusters of broadly clavate, inflated cells around the base.
PS: What is the appropriate terminology regarding metuloids / cystidia with crystals?
Utriform, clavate-ventricose, and filiform caulocystidia at apex of stipe.

BTW, cool spores; it’s amazing that there can be such a dramatic range of spore shapes in the genus Inocybe….your “lemon-shaped” ones vs those nodular ones that I posted recently look like they are from a whole nuther planet! Yet the fruit bodies themselves are quite similar.
This didn’t key out very convincingly in Nishida’s Key to CA Inocybe. Any ideas?
