35.765  -82.2652 +-1000m.
Elevation: 1951 meters
Verbatim Elevation: 6400 ft
Habitat: Abies fraseri forest with some Picea rubens and Tsuga
Substrate: on soil
Description: Stipe darkens with age, pileus 15-30 mm wide, stipe 30-40 x 3 mm, base bulbous "marginate"; spores 7-9 x 5.5-6 microns, nodulose with 6-8 moderate-sized nodules about an often angular outline, occ. tetrahedral; cystidia fusiform to ventricose or almost saccate, apically thick-walled up to 2.5 microns thick, mostly hyaline, not long (43-51 x 14-18 um); basidia 4-sterig.
Occurrence Remarks: Inocybe nodulosa ITS same as PBM4064, somewhat surprising except for the marginate stipe base.
Field Notes: Possibly Inocybe sphagnophila given the bulbous stipe base, but the number of nodules is far less than described for this species and the fbs do darken as in the description for ericetorum. The last ericetorum I identified turned out to be I. sphagnophila based on ITS (PBM4325).
