Spores; Habitat: Artemisia tridentata - Agropyron spicatum grassland; Location: Bitterroot Valley, T9N R19W S18; Substrate: Branch, Artemisia tridentata; Elevation: 1035 meters; Notes: Spribille 2014: Maybe it is L. scabridula then, or something close to L. scabridula and undescribed. The substrate is weird, all other L. scabridula specimens are from conifer wood in a very specific decomposition stage, it seemed like a hyper specialist.
