Specimen notes
Public Note:
Ian Dickie's 5247. This looks more like R. wilsonii. [JAC 2/2012]. Note that it is considerably smaller and with smaller spores and so must remain doubtful. I believe the scale in the photograph must be incorrect. Cap SV-ve on perimeter, granular reaction in centre, exuding pink pigment. Cap without cystidia, with hairs, arising from a disoraginsed trichoderm (relative to mcnabbii) to 60um, and basal layer of spherical cells to 50um thick, over disorganized periclinal filamentous layer. Hairs septate, to 180um. Difficult to determine if hairs from spherical cells or not, one seen with bifurcate base, but still possibly arising from easily collapsing spherical cells in sub-pellis (they must arise from these?). Cap subpellis appears to have weak amyloid (green) reaction. Tipe of hairs often with granular encrustation.. Some (many) gill macrocystidia are thick-walled, or at least glassy-walled. Apex of stem with caulocystidial hairs like cap. Spores from gill length=7.0–8.6µm (µ=7.7, σ=0.43), width=5.8–7.6µm (µ=6.6, σ=0.48), Q=1.1–1.4µm (µ=1.18, σ=0.07), n=20, ornamentation to 1um
