200–1,500 ft · OR🚗 Directions
Portland-area lowlands including the Willamette Valley, Sandy River corridor, Clackamas River drainage, and lower Columbia River Gorge. Prime spring morel territory at low elevations where soil warms weeks before the Cascades. Cottonwood river bottoms, old orchards, and urban bark mulch are key habitats.

The Willamette Valley / Columbia Gorge grades Good, but it's carried by a narrow set of species rather than broad conditions. Soil is sitting at 48.4°F with no drought flag and a met moisture trigger, but you've had 0" in the last 7 days and only 0.14" over 14, so moisture is the limiting factor. Chanterelle is your high-confidence play, along with the cool-soil fruiters that clear their thresholds: Wavy Cap, Flying Saucer, Conifer Psilocybe, Stuntz's Blue Legs, Bottle Cap, and Allen's Psilocybe. Hedgehog, Yellow Foot, Angel Wings, Tooth Jelly, Jelly Antler, and Red-Belted Conk are viable at moderate confidence, with soil clearing their 50°F minimums for 7/7 days. Anything wanting 55-58°F (parasols, waxcaps, inky caps, puffballs, meadow and horse mushrooms, Shaggy Mane) is marginal at best, since soil has only cleared those minimums 4-5 of the last 7 days and is trending cool. Watch for rain: a soaking system would push moisture past marginal and trigger a real flush, while continued dry weather will stall fruiting and desiccate what's already up. Cooling soil in the coming days will further erode the warm-preference species. Hot tip: Hunt north-facing, duff-heavy conifer and mixed hardwood stands near drainages and seeps for chanterelle and hedgehog, since retained ground moisture there matters more than the regional numbers right now.

⚠ 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.
