The stipe was central. The outside of the stipe was smooth, and it was 4.8 cm long and 2.7 cm wide. It had a clavate shape overall, and the inside of the it was solid. The outside of the stipe was brown, but the inside was white. With air exposure, the inside turned from white to brown. The base was institutious.
