Burning Finger Lichen
Dufourea flammeaAlso known as Orange Finger Lichen, Flame Lichen
Burning finger lichen forms dense tufts of vibrant orange, finger-like lobes that project outward from coastal boulders and maritime chaparral shrubs along the Pacific fog belt. Its intense anthraquinone pigments act as a natural sunscreen, shielding the delicate symbiotic green algae within from harsh ultraviolet radiation. The thallus absorbs moisture and trace minerals directly from dense sea fog rolling off the cold ocean.

- Why interaction risk is low
- Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Tread Carefully: Watch where you step on coastal rock outcrops to avoid crushing delicate thalli.
- Morning Fog: Observe during damp conditions when the swollen lobes appear most vibrant.
