The Atchafalaya Basin earns an Excellent grade because every trigger is satisfied at once. Soil sits at 70°F and has stayed above threshold all 7 of the last 7 days. Moisture is sustained, with 0.21 VWC today against a 0.24 seven-day average. About 3.4" of rain landed in the past week, there is no drought, and the moisture trigger is met. Nothing is limiting, so the whole species list is viable at high confidence, with the best odds on the Louisiana staples: oysters (including elm and aspen on dead hardwood), chanterelles, chicken of the woods, lion's mane, honey mushrooms, wine caps, and the puffball and parasol crowd on higher ground and edges. The deadly lookalikes are also fruiting at full tilt, so Death Cap, Destroying Angel, and Deadly Galerina all show high; sort your Amanita and Galerina from your honeys, parasols, and meadow mushrooms by spore print and base structure, not by habitat. Soil moisture is already drifting slightly below its weekly average (0.21 vs 0.24), and almost all of the 3.48" over 14 days fell in the last week, so watch for a dry-out. If no fresh rain comes, flushes of the fast, fleshy species (inky caps, oysters, shaggy manes) will peak and fade within days, while the polypores and conks will hold longer. Hot tip: Hit hardwood-heavy ridges and downed elm and oak first for oysters, chicken, and lion's mane, since they'll fade fastest if the moisture average keeps sliding, and save the slow-holding conks and polypores for later in the week.

⚠ Road Access Notice
