Mobile-Tensaw Delta — second-largest river delta in the US, bottomland hardwood swamp and cypress-tupelo brakes at the head of Mobile Bay. Water oak, swamp chestnut oak, bald cypress, water tupelo, and loblolly pine on natural levees. Exceptional oyster mushroom on water oak snags; chicken-of-the-woods; summer chanterelles on higher ground. Blakeley SP, W.L. Holland WMA, Upper Delta WMA for access.

The Delta is operating at peak performance: 11+ inches of rain over two weeks, sustained soil temps at 75°F, and stable moisture at 0.32 VWC across the full observation window. This is the rare S-tier window where nearly everything fruits simultaneously—wood-decayers (oysters, wine caps, turkey tails), cup fungi (eyelash, green elfcup), polypores across the board, and even the morels that usually demand spring precision are viable right now. Zero limiting factors means no substrate is drying out, no temperature swings are stalling flushes, and wood moisture is at saturation. The real play is substrate diversity: hit your dead hardwoods for oysters and aspen oysters (they're in explosive mode), scan moss-covered logs for jelly ears and wood ears, and work standing deadfall for the polypore suite. The moisture is locked in, so fruiting bodies won't abort mid-formation over the next 72 hours. Hot tip: Target fresh woody debris in wetter microtopography (creek edges, seepage zones) where Wine Caps and Dryad's Saddles will fruit ahead of drier areas—they're moisture-hounds and this window won't last forever once late May heat 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.
