Shawnee National Forest in southern IL. Oak-hickory forest with tulip poplar and sycamore in drainages. Sandstone bluffs create unique microclimates. Old apple orchards scattered throughout. Among the best morel territory in IL.

**Shawnee NF is firing on all cylinders—this is a peak generalist window.** You're looking at S-tier conditions because soil temp (75°F) and moisture (0.17 VWC, 7-day avg 0.20) have held steady across a full week with zero drought stress. That's your unlock for the entire catalog: edibles (Chicken of the Woods, Black Trumpets, Chanterelles, all milk caps), medicinals (Turkey Tail, Artist's Conk, Birch Polypore), and yes—the dangerous stuff (Death Caps, Destroying Angels, Deadly Galerinas). There are no limiting factors. The 0.88" last week plus no drought signal means substrate is fully charged without being waterlogged. Focus the visible ground: Chicken of the Woods on dead oak/hickory, Black Trumpets in rich duff, Parasol and Shaggy Parasol in open glades, and milk caps under their host trees. Polypores are year-round, so work woody debris systems. The wood ears and jelly fungi will be obvious on wet logs. Watch the next 72 hours—this condition tier typically peaks mid-week then drops as soil dries unless another rain system moves in. If you see clearing skies and temps staying 70+°F, the window compresses. **Hot tip:** Forget the common targets and hunt hedgehogs and two-colored boletes in oak-hickory understory—they're less pressure, equally productive right now, and the terrain scouts easier than chasing Chicken of the Woods.

⚠ 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.
