cap has a short stem with a rounded attachment. Though small and a quiet brown in color, these mushrooms possess a surprising quality; they glow in the dark. A handful of these, gathered when fresh, can be placed in a jar, dotted with water and covered. In a dark room, caps will produce a steady greenish glow. It’s possible, if caps are kept slightly moistened, to keep them glowing for a week
or more. The mushroom’s common name is fittingly Luminescent Panellus.
