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 Good grade comes from soil at 64.4°F, held above threshold for 7 of 7 days, with no drought and the moisture trigger met. Moisture is the limiting factor: 0.68" over 7 days and 1.77" over 14, with soil moisture at 0.16 VWC against a 0.18 weekly average. That is marginal and trending slightly drier, so flushes will be patchy rather than explosive. Every species in the model shows high viability, but in practice the best bets are the wood-based and moisture-buffered fruiters: Chicken of the Woods, Hen of the Woods, Lion's Mane, Honey Mushroom, Beefsteak Polypore, Black Trumpet (6/7 days on temperature, so the weakest of the group), and the oak-associated chanterelles and milk caps. Fast, soil-dependent species like Shaggy Mane, Wine Cap and the inky caps will lag until you get another soaking rain. Watch the forecast for a half inch or more in the next few days, which would push this toward Excellent. If it stays dry, expect the surface-fruiting species to stall first while the log and stump species hold on. Death Cap is also flagged as viable. Treat it as a presence warning on oak and hardwood ground, not a target. Hot tip: Hunt north-facing hollows and drainage bottoms near mature oaks, where the duff holds moisture longer, and check standing and downed hardwood for polypores and Lion's Mane before the dry trend sets in.

⚠ 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.
