NOTABLE PHENOMENA.

There are no phenomena associated with fungi that are of greater
interest than those which relate to luminosity. The fact that fungi
under some conditions are luminous has long been known, since
schoolboys in our juvenile days were in the habit of secreting
fragments of rotten wood penetrated by mycelium, in order to exhibit
their luminous properties in the dark, and thus astonish their more
ignorant or incredulous fellows Rumphius noted its appearance in
Amboyna, and Fries, in his Observations, gives the name of _Thelephora
phosphorea_ to a species of _Corticium_ now known as _Corticium
caeruleum_, on account of its phosphorescence under certain conditions.
The same species is the _Auricularia phosphorea_ of Sowerby, but he
makes no note of its phosphorescence. Luminosity in fungi "has been
observed in various parts of the world, and where the species has been
fully developed it has been generally a species of _Agaricus_ which
has yielded the phenomenon."[A] One of the best-known species is the
_Agaricus olearius_ of the South of Europe, which was examined by
Tulasne with especial view to its luminosity.[B] In his introductory
remarks, he says that four species only of Agaricus that are luminous
appear at present to be known. One of them, _A. olearius_, D. C., is
indigenous to Central Europe; another, _A. igneus_, Rumph., comes from
Amboyna; the third, _A. noctileucus_, Lev., has been discovered at
Manilla by Gaudichaud, in 1836; t
