**Western MD Catoctin — S Tier, Late May Sweet Spot** This region has hit the perfect convergence: seven consecutive days above soil temperature threshold, sustained volumetric water content at 0.28 (7-day average), and fresh precipitation across a two-week window without drought stress. The S tier reflects a rare breadth of simultaneously viable species—31 taxa spanning saprophytes, wood decomposers, and specialists are all firing at once. Oysters, Wine Caps, and Dryad's Saddles are your volume plays; the polypores (Artist's, Birch, Red-Belted Conk, Thinwall Maze) are dependable; and the jelly fungi (Witch's Butter, Wood Ear, Snow Fungus) are at peak condition. The only real friction is moderate desiccation risk—you're not in a drought, but the margin for error shrinks if we see a dry spell. The good news: three of the last four days have delivered moisture, so soil reserves are topped off. Watch the next 72 hours for any high-pressure system that could dry the litter layer; if it stays cloudy or another rain comes, you've got a 10–14 day window. Hot tip: Hit dense Dryad's Saddle patches now—they fruit hardest right after sustained rain like this and will senesce fast once desiccation risk climbs.

⚠ 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.
