were tried to ascertain the best media upon which to cultivate it. 
A number of substances, viz., potatoes, slices of bananas, banana 
skins, slices of orange, Neuchatel cheese, orange peels, slices of 
apple, prune broth, stewed prunes, molasses, pine charcoal and 
bread were used as culture media. The pine charcoal was tried, 
because the fungus was found growing on burned trees. Spores 
were sown by means of a sterilized platinum loop wetted in dis¬ 
tilled water and applied with the spores to the surface of the 
several culture media. The following account gives in synopsis 
the results obtained. 
Potato (raw and cut open).— No perceptible growth. 
Banana Slices. — No growth of Monilia, but a rich develop¬ 
ment of Penicillium glaucum Link, and later of Rhizopus nigri¬ 
cans Ehbg. 
Banana Skin. — Covered by Penicillium glaucum Link, 
and a small round patch of Monilia. 
Orange Slices. — Invaded by Penicillium and Rhizopus. 
Orange Peels. — Not suitable for Monilia. 
Apple Slices. — No development of the orange-yellow 
fungus. 
Prune Broth. — Monilia made a rapid growth upon the sur¬ 
face of the broth, the conidial chains being formed most plenti¬ 
fully along the edges of the Petri dishes in contact with the air. 
Stewed Prunes. — This culture material was covered by a 
luxuriant growth of Rhizopus, later by Penicillium and a scatter¬ 
ing growth of Monilia between the denser mycelia of the above 
named moulds. 
Neuchatel Cheese. — No development of Monilia martini 
S. & E. var. incendiarium E. & E. 
Molasses. — No growth of any sort, although a rdtntiful sup¬ 
ply of spores was sown. 
Pine Charcoal. — Spores of the fungus studied were sown 
upon the surface of several charcoal blocks. Monilia, although, 
as its varietal name implies, made a growth on this medium. 
Bread. — Of all the materials experimented with, bread was 
found to be the most suitable substance upon which to grow 
Monilia martini S. & E. var. incendiarium E. & E. The fungus 
later was kept for several months in a flourishing condition on 
bread alone. Upon bread, it forms a white, cottony mycelium, 
later, as the conidia are formed, assuming an orange-yellow 
color. Three to five days elapse, depending upon the weather, 
from the time the spores are sown until a new crop of spores is 
obtained. The fungus can be kept alive for about three weeks, 
when another sowing upon fresh bread should be made.
