Bitterroot / Sapphire

**Tier A is solid, but it's a drying window—act now.** You've got sustained warmth (76°F soil), seven consecutive days above threshold, and the moisture trigger confirmed, which puts everything from Reishi and Indigo Milk Caps to Birch Boletes and The Prince in play across elevation. The breadth here is exceptional: woody species (Chaga, Birch Polypore, Red-Belted Conk) are locked in, while epigeous fruiters (Scaler Stalks, The Prince, Coker's Amanita) are primed. The limiting factor is desiccation risk—that 0.01" precip in the last seven days and complete snowmelt mean soil moisture is stable *right now* at 0.16 VWC, but there's no rain buffer. You've likely got 3–5 days before capillary moisture drops enough to stall fruiting. Focus on lower-elevation (3,500–5,500 ft) north-facing slopes and drainages where residual melt seepage persists; those microclimates will hold fruiting flushes longer. Watch the next 48 hours for early Birch Bolete and Prince emergence—these are your canaries. **Hot tip:** Get to north aspects before midweek heat hits; Indigo Milk Caps and Birch Boletes fruit heavy-to-flush under this profile, but only if soil stays above 0.15 VWC.
