Located on a well-rotted ponderosa pine log, west of the highway 140 and just south of the Wawona Camp ground.

The genus name changed since the Pt. Reyes collection of this species.

The thickwalled hyphae are supposed to be faintly amyloid. Maybe this true on this specimen, but it takes some imagination. They look more faintly dextrinoid to me.
