White Clay Creek SP and Brandywine Creek SP — Piedmont hardwood forest in northern DE. Beech, tulip poplar, oak, and hickory on rolling terrain. Spring morels in disturbed bottomland; chanterelles in oak-beech in summer. Suburban-fringe foraging for the Wilmington/Philadelphia area.

White Clay Creek is locked in Tier A because soil temps have climbed to 65°F with 3.3" of rain in the last week sustaining 0.22 VWC—that's the sweet spot for both saprophytic and wood-decay species simultaneously. The moisture trigger is met and holding steady, unlocking the full spring-early summer roster: prioritize Dryad's Saddle and Half-Free Morels first (they're on the clock), then pivot to Wine Caps, Oysters, and the polypore suite (Turkey Tail, Artist's Conk, Birch Polypore) which will fruit consistently through the window. Desiccation is flagged as the limiting factor, which means you're in a race—conditions are ideal *now*, but a dry spell will collapse this tier fast. Watch the 7-day precipitation trend obsessively; even three days without rain at this soil temp will start shutting down the saprophytes and pushing you toward reliance on established wood-decay fruiting bodies. **Hot tip:** Dryad's Saddle fruits in a narrow window around 65°F soil; if you're not out in the next 2–3 days, you'll miss them as temps climb and soil moisture drops.

⚠ 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.
