Northeast Ohio including Cuyahoga Valley NP and surrounding Geauga and Portage county woodlands. Beech-maple forest with scattered ash and elm. Lake Erie moderates temperatures, delaying but extending the morel window.

# NE Ohio S-Tier Flush: Late May Sweet Spot You're in a rare convergence—sustained soil warmth (58°F for 5+ days), solid moisture profile (0.28 VWC 7-day average, no drought stress), and zero limiting desiccation risk right now. This is textbook late-spring activation across your entire woody/saprotroph guild. Wine caps, Dryad's saddles, and half-free morels are prime; the polypores (Artist's Conk, Red-Belted, Birch) are all firing. Fairy Ring Champignon is the only holdout—mycelium is hot but primordia haven't pinned yet; it'll break in 2–3 days once that 4/7 threshold becomes 6/7. The single limiting factor is moderate desiccation risk creeping in—watch your 7-day precipitation trend. You've got 2.23" over 14 days; if the next 48 hours stay dry, watch for a hard brake on the wine cap and softer species. Hardier perennial polypores won't care. **Hot tip:** Hit your ash and cottonwood stands *today* for Dryad's saddle; they flush hard on this soil-moisture window and fade fast once soil hits 62°F.

⚠ Road Access Notice
Always verify road access is public before following GPS directions to mountain areas. Many forest roads are seasonal, gated, or require 4WD. Dispersed camping follows USFS/BLM rules (typically 14-day limit). Check ranger district offices for current road and campground conditions.

Primordia readiness: Cold = mycelium dormant. Activating = soil warming, primordia building. Primed = 5+ sustained warm days at species threshold; fruiting imminent if moisture cooperates. Based on Schmidt 1983 / Mihail 2007.
