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 grades Good on the strength of a solid moisture setup: no drought, 3.69" over 14 days, and the moisture trigger is met. Soil is the real story at 46°F, which sits below the minimum for most of the species list. Only the cold-tolerant group (Lion's Mane, Hedgehog, Yellow Foot, Red-Belted Conk, Angel Wings, Amanita muscaria, jelly fungi) has held 7/7 days above threshold, and Stuntz's Blue Legs is the only species with all conditions fully met. Warm-season fruiters like Chicken of the Woods, Black Trumpet, Shaggy Mane, parasols, and the waxcaps are effectively done for the year, and Hen of the Woods and Honey Mushroom (3/7 days above) are fading. The limiting factor is marginal moisture with moderate desiccation risk: only 0.31" fell in the last 7 days, and VWC is sitting at 0.15 against a 0.17 weekly average, so the trend is drying. Watch for any rain event, since a soaking would sustain the cold-tolerant flush, while another dry week with cooling soil will shut down the remaining marginal species. Hot tip: Target Stuntz's Blue Legs in your usual spots and Lion's Mane or Hedgehog in sheltered, moisture-holding stands, and skip the warm-season targets.

⚠ 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.
