Thuja plicata
"Helvella corium" has been collected from Asia, Europe, and North America. Fruit bodies grow solitary, scattered, or clustered in groups. It is often found in association with the trees "Populus tremuloides" or "Thuja plicata", or with shrubs from genus "Salix" (such as "Salix herbacea" and "Salix glauca"), "Shepherdia canadensis" or shrubs from the genus "Dryas". Jordan notes a preference for growing on sandy soils or in dunes.
