"West Coast counterpart of Wavy Cap, named for ethnomycologist John W. Allen. Indistinguishable in the field; DNA pulls them apart. Park-edge wood chips, urban landscaping."
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.
Named in 2012 for ethnomycologist John W. Allen. Visually indistinguishable from Psilocybe cyanescens (Wavy Cap) — the split was driven by DNA. Slightly flatter cap on average and concentrated west of the Cascades. Contains psilocybin and psilocin.
Urban and park-edge wood chips along the West Coast from southern British Columbia to central California. Fruits in late fall through midwinter.
