NOTES ON FLORIDA FUNGI.-No. 5. 
RY W. W. CALKINS, CHICAGO, ILLINOIS. 
Ill previous papers, I mentioned some of the most prominent species 
of fungi,— or such as would naturally claim the attention of a tyro • 
in this study. In this, I will consider a few forms that are not found 
without considerable trouble, much hard work, and frequently an abun¬ 
dance of bruises and scratches, to say nothing of the danger incurred 
from arousing a snake from its lair. I have often gone over a piece of 
woods and secured, as I supposed, everything of value, but repeated 
trials on the same ground have convinced me of my error and surprised 
me by the results obtained. In Florida there are some species found 
only in certain favorable localities and in certain woods. Polyporm^ 
Salleanus, B., a most beautiful species, and not common, occurs on dead 
hickory limbs lying on the ground and more sparingly on Magnolia 
glaxica. Leuzites cormgata, is found on old limbs in moist places. Hy- 
(Inimi Iceticola, B. & C., is very rare here, but line, and can only be found 
by searching on low grounds very closely, and then weeks may pass 
without tinding it. Hydniira fra.gilli^simum, B. C., is equally rare and 
only a few specimens have rewarded my efforts. Both of these species 
affect the under side of rotten limbs in dark forest shades. KneifUa 
SeHgera, Fr., in the same situations, is also not common. 
PHOSPHORESCENT FUNGI. 
Some time last fall (1885), Prof. Thos. G. Gentry, of Philadelphia. 
Pa., called my attention to the fact that Panus fftypticus, Fr., is phosphor¬ 
escent. Prof. G. had collected some specimens of this species and laid 
them with other fungi on a shelf to dry. On examining the specimens 
the same evening, it was found that the gills of the Panus were dis¬ 
tinctly phosphorescent, a fact which I have been able to verify by my 
own observation of specimens, soon after collected at Xewfield. By care¬ 
ful examination, tlie luminosity was found to proceed from the gills and 
not from the stipe, nor from the upper surface of the pileus, nor, finally, as 
was at first suspected, from any fragment of rotton wood attached to the 
specimen. This phosphorescence was not observed in all specimens 
brought in for examination, and seemed to depend on some peculiar con¬ 
dition of the air, having been noticed only in specimens gathered in damp 
weather or just before a storm. 
In his “ Introduction to Cryptogamic Botany,’’ p. il65, Berkeley 
observes that “ this luminosity has been noted in various parts of the 
world ; and where the species has been fully developed it has been gener- 
:illy some species of Agarlntfi that has yielded the phenomena. Ag(trlcnfi
