**Olympic Peninsula Tier A – Drought-Held on Knife's Edge** You're sitting Tier A on breadth alone—this region *can* support 60+ species—but the persistent drought is the real story. Two weeks of near-zero precipitation has locked soil VWC at 0.10, and that's the hard ceiling right now. Species like Reishi, Chaga, Birch Bolete, and Amethyst Deceiver are your best marginal bets since they tolerate drier conditions longer, but even they're playing edge cases. The 54.5°F soil temp is barely limping along, keeping cool-season fruit bodies suppressed across the board. This ranks A because the *infrastructure* is there—old-growth timber, conifer-hardwood mosaic, mycorrhizal networks all primed—but you're not going to see meaningful flushes until moisture breaks. Spotting will be scattered and thin. Watch the forecast hard: even 0.3–0.4" of rain in the next 72 hours would shift several species into reliable territory. A soaking event breaks the whole dynamic open. **Hot tip:** Target north-aspect ravines and seeps where water pools during dry spells—Reishi and polypores fruit in those microclimates when everything else sleeps.

⚠ 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.
