Catoctin Mountains and Western Maryland — Appalachian oak-hickory transitioning to northern hardwoods at higher elevation. Catoctin Mountain Park, Savage River SF, Garrett SF. Excellent spring morels in tulip poplar coves and dying ash flats. Chanterelles and chicken in summer.

Western MD/Catoctin sits at Good: soil is 57.4°F with no drought, snowpack is irrelevant, and the moisture trigger is technically met. But 0.06" over 7 days and 0.25" over 14 is thin, and the 0.17 VWC today (down from a 0.20 weekly average) shows the duff drying out. Moisture is the limiting factor, with moderate desiccation risk. Soil temps are comfortably in range for the fall wood-rotters and mycorrhizal crowd: Honey Mushroom, Oyster, Angel Wings, Hen of the Woods, Lion's Mane, Hedgehog, Blewit, Wine Cap, Beefsteak Polypore, Red-Belted Conk, and Turkey Tail all rate high. Warm-season holdouts like Chicken of the Woods, Black Trumpet, and the stinkhorns (Ravenel's, Elegant) are marginal on temperature, and the 58°F-minimum group (Shaggy Mane, Giant Puffball, parasols, meadow/horse mushrooms, waxcaps) has only 3 of 7 days above threshold, so expect sparse flushes there. Watch for rain: a soaking half-inch or more would push the high-rated species into a real flush within 5-10 days, while continued dryness plus falling soil temps will shut down the marginal group and shrink everything else to protected microsites. Hot tip: Hunt north-facing hollows, stream drainages, and big standing or downed hardwood (oak especially) where wood holds moisture. Honey Mushroom, Hen of the Woods, and Oyster on logs will outlast anything out in dry open ground.

⚠ 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.
