# Central MI – Tier A | May 29, 2026 You're in a sweet spot: soil temp has hit the magic 62°F threshold and stayed there for a week, moisture is locked in at 0.22 VWC average, and precipitation is consistent without saturation. This is textbook spring flush territory—nearly every saprophytic and wood-decay species in the region is firing simultaneously. Wine Caps, Dryad's Saddles, Turkey Tail, and the full constellation of polypores are all live right now. The limiting factor is desiccation risk—don't sleep on it. You've got sustained moisture, but late-May sun intensity in Central MI ramps fast. Prioritize morning harvests and focus on north-facing woodlots, shaded stream corridors, and dense understory where humidity buffers the afternoon burn. The next 72 hours are critical; if you see the soil moisture dip below 0.18 VWC or get 5+ days of dry conditions, the window collapses. Wood-decay species (Chaga on birch, conks, polypores, Jelly Ear) are your safest bets—they're moisture-buffered by their substrate. Ground-fruiting species like Half-Free Morels and the inkcaps are higher-risk in drying trends. **Hot tip:** Dryad's Saddle bases are still tender—get under any dying elm or ash in moist draws before the sun hardens them Friday.

⚠ 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.
