Sprawling 1.5M-acre national forest across southern Missouri. Shortleaf pine mixed with oak-hickory-ash hardwoods. Old apple orchards and abandoned homesteads scattered throughout — classic morel micro-habitat. Less crowded than Ozark Highlands but requires more scouting.

**Mark Twain S-Tier: Late Spring Flush In Full Effect** This region is locked in S-tier because soil temps hit the magic 71°F threshold and have held there for a full week with sustained moisture—0.21 VWC today, holding at 0.20 over the rolling average. That's the sweet spot: warm enough to trigger fruiting, wet enough to sustain it. Dryad's Saddle and Half-Free Morels are your headline act right now, but the wood-decay species (Wine Cap, Turkey Tail, Artist's Conk, Aspen Oyster) are equally aggressive. Polypores and jelly fungi are all firing; this is a polyculture moment. The only real constraint is moderate desiccation risk—you've only pulled 0.94" in the last week, which is thin. Watch the forecast closely; if you get three dry days in a row without supplemental rain, the VWC will crater and the window closes hard. Check daily through early June. The gelatinous species (Jelly Ear, Wood Ear, Snow Fungus) will be among the first to decline if drying accelerates. **Hot tip:** Hunt north-facing slopes and low-lying draws where soil stays coolest and moisture pools longest—desiccation risk is real even in S-tier, and aspect is your margin of safety here.

⚠ 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.
