"Spring-fruiting Psilocybe of mid-Atlantic riverbeds and mulched landscaping. Caramel cap, blue-staining stem. Spread fast along the east coast in the 2000s — a new neighbor."
This species is found with or partners with the following hosts. Ectomycorrhizal hosts (green border) form a root-level partnership; ericoid / arbutoid shrubs (purple border) share the same mycorrhizal networks.

Landscape hardwood chip mulch — wine cap, bird’s nest fungi, dog-vomit slime mold. A great backyard cultivation substrate.
A spring (and second fall) fruiting Psilocybe of the mid-Atlantic and eastern US, found in mulched landscaping and along river bottoms. Distinguished by its ovoid spore shape under a microscope; in the field it looks like a smaller, paler Wavy Cap. Spread rapidly along the east coast in the 2000s.
River-bottom wood debris, mulched landscaping, and disturbed riparian soil from Pennsylvania south to North Carolina, with outlier populations in Oregon. Spring is the main flush; some populations fruit again in autumn.
