Grows in humus enriched with woody debris, amongst leaves and twigs, in wood chips, sawdust, or in debris fields rich with rotting wood. Often under mixed woods at the edges of lawns, along paths, and in heavily mulched rhododendron and rose gardens. Found in the fall to early winter in the Pacific Northwest. Reported from the western coastal regions of North America (from San Francisco, California to southern Alaska), and also widely spread throughout the United Kingdom, across much of temperate Europe, from Italy to Germany to Spain to Sweden.
