# Minnesota River Valley – Tier A, Late May Peak You're in a rare sweet spot: soil has cracked 73°F on sustained moisture, no drought stress, and two weeks of moderate precipitation have primed the substrate. The tier-A lineup here is unusually deep—wood-decay species (oysters, turkey tail, conks), spring ephemerals (half-free morels, dryad's saddle), and gelatinous forms (jelly ear, wood ear, witch's butter) are all live simultaneously. The limiting factor is desiccation risk; this is the window before late-May heat and reduced rainfall start drying things out. Don't sleep on the hardwood polypores and conks—they fruit reliably in the valley's riparian strips and will sustain through dry spells once established, but *getting them to fruit* depends on the next 5–7 days staying moist. Morels and dryad's saddle are closing fast; prioritize low-lying hardwood and ash zones near the river corridor. **Hot tip:** Scout decaying aspens and birches along floodplain margins *tomorrow*—half-free morels and aspen oysters peak exactly when soil hits this temperature-to-moisture ratio, and you've got 48–72 hours before thermal evaporation kills the flush.
