A thousand points of light: Bioluminescent fungi

Late in the afternoon on a new moon day, we gear up: hiking boots, long pants, long-sleeved shirts, belts with knives and GPS units attached, hats with headlamps, and backpacks filled with water, snacks and plastic collecting boxes. Our expedition of seven members climbs into a 4x4 and drives 30 minutes over dirt roads into the jungle. Arriving at the trailhead near dusk, our local guide (we call him the human GPS) leads us on a six kilometer hike deep into the heart of the forest.
