Acadia NP and surrounding Down East coast. Mixed spruce-fir and northern hardwood forest on granite terrain. Morels fruit in May-June in old apple orchards and disturbed ground with elm and ash. Black morels reported in burned areas after prescribed fires. Chanterelles (golden and black trumpet) Jul-Sep in mossy spruce-birch forest. Fog-moderated coast extends season. NPS permit rules apply inside Acadia.

**Acadia Down East – A Tier | May 29, 2026** True Morels are peaking right now—soil temp and moisture alignment are locked in, and you're in the optimal window before that desiccation risk tightens the noose. Red-Belted Conks are also going strong if you're wood-hunting, and the perennials (Chaga, Artist's Conk, Turkey Tail) are viable despite marginal soil temps because they're not temperature-dependent foragers. The catch: everything else is temperature-marginal and fighting uphill against the soil being 2°F shy of ideal, so focus your energy on the morels before the soil warms and flushes the flush. Watch the next 48 hours closely—if soil temps push past 55°F without proportional moisture increase, half these moderate-viability species will crater. The real limiting factor isn't rain; it's that you're on the knife's edge between cool-season and warm-season fruiting, and desiccation will collapse the window fast once soil dries. **Hot tip:** Hunt south-facing slopes in mixed hardwood—they'll be 2–3°F warmer and morels will fruit earlier there, buying you time before heat-stress sets in.

⚠ 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.
