Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Notes:
Wiry-tough dark brown/smokey gray/nearly black stipes are nearly 2 inches tall; cap yellow with brown tints; base of stalk with brown mycelium. Clustered on well-rotted wood, possibly vine maple. I suspect the caps would be much more brightly colored if rehydrated or fresh. They look like they dehydrate quickly, with almost no cap flesh, slightly decurrent brownish-orange gills to dark brown; stipe thin but very tough. I’ll let the photos do the rest of the telling.

X. campanella indistinguishable from X. enigmatica without mating studies or DNA

Xeromphalina campanella can be distinguished from X. enigmatica only by mating studies or DNA sequencing. They’re effectively identical in macroscopic features, microscopic features, chemical features, geographic location, and substrate preference.
