Phosphorescent funguses have been found in Brazil by Mr. Gardner,
growing on the decaying leaves of a dwarf palm. They vary from one to
two inches across, and the whole plant gives out at night a bright
phosphorescent light, of a pale greenish hue, similar to that emitted
by fire-flies and phosphorescent marine animals. The light given out by
a few of these fungi in a dark room is sufficient to read by. A very
large phosphorescent species is occasionally found in the Swan River
colony.
