Angeles NF / San Gabriel Mountains

**Angeles NF / San Gabriel Mountains — Tier A, August 27** You're looking at a narrow window driven by residual soil moisture, not active precipitation. Two weeks bone-dry with VWC hovering at 0.09 means everything is running on fumes—this tier reflects *what could fruit* if conditions hold, not what's actively popping. King Boletes and Oysters are your highest-probability targets since they can exploit shallow subsurface moisture and established mycelial networks, but expect sparse, scattered fruiting rather than flushes. Stinkhorns (all four species) are your sleeper play—they're moisture-tolerant and often emerge after dry spells when soil temps stabilize; you'll find them in sandy/gravelly areas where capillary moisture persists. The hard ceiling is desiccation. Without rain in the next 5–7 days, soil VWC will crater and fruiting odds collapse. Watch the afternoon relative humidity and any cloud build over the high ridges; even a trace moisture event could trigger stinkhorn emergence. **Hot tip:** Hunt north-facing slopes and canyon bottoms where soil retains moisture longest—boletes and oysters will cluster there while the south faces are already drying out.
