Southern Iowa rolling hills with oak-hickory forest remnants and old apple orchards. Stephens SF, Lake Red Rock area, and scattered timber along creek corridors. Dying ash and elm are reliable morel producers.

## Southern Iowa – S Tier (July 13, 2026) This region is firing on all cylinders: soil temp is locked at 74°F with a full week of sustained warmth, and volumetric water content has held steady at 0.21—right where fruiters need it. The 57-species roster is exceptionally broad because *both* wood-decay and ground-fruiting fungi are equally dialed in. You're looking at prime season for Chicken of the Woods and Wine Caps on dead timber, Inky Caps and Fairy Ring Champignons in open ground, and the full bolete spectrum where mycorrhizal networks are active. The only brake here is **moderate desiccation risk**—that paltry 0.32" of rain in the last week means the soil moisture is stable but not climbing. The next rain event is your window to extend peak conditions; without it, soil VWC will decline gradually over 7–10 days, dragging species toward A-tier territory. Watch the forecast hard. A 0.5"+ event in the next 3–5 days locks in another week of S-tier productivity. Dry spell? Plan your high-value targets now—Boletes and chanterelles will start dropping off first as upper soil layers dry. **Hot tip:** Parasol and Shaggy Parasol prefer the *driest* edge of viable moisture; hunt them today and tomorrow before any hypothetical rain plumps up the competition.

⚠ 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.
