Growing on serpentine, causing an obvious rusty halo on rock at edge of thallus. Habit: fully exposed serpentine ridgeline.

Under canyon live oak, Jeffrey pine, knobcone pine, with manzanita and white fir nearby. Discoid/angular with silky yellow cortina persisting and becoming shaggy, attached to edge of abruptly bulbous base. Very slow (~2 minutes) pink-red KOH reaction on stipe and cap. Stipe yellow UVF like Leprocybe, becoming more neon-blue/green/yellow where stained by KOH. Gills with mottled yellow-green UVF. Mild taste. Petrichor and watermelon rind odor.
