Observation 67007: Botryobasidium subcoronatum (Höhn. & Litsch.) Donk
When: 2011-05-01
Herbarium specimen reported

Notes: Fruiting on the underside of wood in a Ponderosa pine, Incense cedar, black oak forest.

This could be a Sistotrema, because some of the basidia could be interpreted as urn-shaped (see last photo), but most seem more cylindrical. It fits B.subcoronatum fairly well, in that it has large basidia for the genus and spores of the right size and shape.

here is a basidium that looks vaguely urn-shaped and makes me worry that this is actually a Sistotrema
