Hairs on stipe exceeding 200µm were seen on microscopy, with brownish colored walls in KOH. Spores oval, smooth, of variable size but average 20×12 µm.

This collection and one other of the same species were made during an outing of the Arizona Mushroom Club. David Arora was a guest, and discovered and identified this collection.
