A newly identified luminescent fungus called Mycena luxaeterna was
discovered in a forest in Sao Paulo, Brazil. The mushroom caps are tiny,
under a half inch (8 mm) in diameter and the stems have a jelly-like
structure. The glow is easier to observe at night (right).

Discovered on the bark of a standing tree in Borneo, Malaysia, this new
glow-in-the-dark mushroom called Mycena silvaelucens emits a
yellowish-green light throughout the day, though it's easier to see at
night (right). Credit: Brian Perry, University of Hawaii

Foxfire
Foxfire is the term for the bioluminescence created in the right conditions by a few species of fungi that decay wood.The luminescence is often attributed to members
of the genus Armillaria, the Honey mushroom, though others are reported, and as many as 71 individual species have been identified.
Armillaria mellea Armillaria hinnulea
Wikipedia > On the suggestion of
Benjamin Franklin (1706–1790) foxfire was
used for light in the Turtle, an early submarine.

Royal Navy Submarine Museum, Gosport, UK
In the novel Adventures of Huckleberry Finn by Mark Twain,
the characters of Huckleberry Finn and Tom Sawyer use foxfire
as a source of light in order to dig a tunnel.

The use of the name "Lucifer" in reference to a fallen angel.
Satan, who in
Milton's Paradise Lost is
also called Lucifer,

the downfall of Adam.

The same Latin word lucifer is used to refer to
the Morning Star, with no relation to the devil.

Angler Fish
Although most marine organisms do NOT use bacteria
to make their light, the anglerfish is an exception.
It, about 4 cm long, cultures a glowing community
inside its retractable lure (called an esca).

Bioluminescence is a form of luminescence, or
‘cold light’ emission; less than 20% of the light
generates thermal radiation.
In the midwater zone (100-1000 meters deep), it has
been estimated that 90% of the fish & crustacean
species are capable of making light, and
the numbers of jellies even higher.
There are no luminous "flowering" plants, birds,
reptiles, amphibians or mammals.

The dials, hands, scales & signs of aviation & navigational instruments & markings are often coated with luminescent materials, in a process known as luminising.

Fluorescence (การืวิาวิแสิ่ง , ฟล่�ออเรืสิ่เซนซ!) Excitation – being hit by light
of particular wavelengths Not stable
Emission – nearly immediately re-emitted in the form of a longer wavelength photon
Phosphorescence (การืเรื�องแสิ่ง) In the past, used as synonym
for bioluminescence Excited state somewhat stable Emission – re-emitted the
energy gradually over time, resulting in a dim steady glow
