SECONDARY CONIDIA. 
The secondary conidia are borne at first in loose, open 
clusters which, after standing for a few days in moist air, 
fall together in rounded masses, adherent to the terminus 
of the conidiophores (pl. 9, f. 6). They are hyaline, 
obovate to club-shaped, and are not guttulate except when 
old. They measure 4y to 8» by ly to 2x, averaging Sy 
by 1.8z. 
PRIMARY CONIDIA. 
The stalks or stromata bearing the heads of primary coni- 
dia are white at first, changing to a yellow color, and often 
to a dark brown at the base (pl. 9, f. 5). They measure 
504 to 7504 by 10uto 90u, and are composed of parallel 
filaments measuring 1“ to 2» in diameter. These bear 
conidia terminally which are held together by mucilage in 
a flattened, oval head, which is white at first, then creamy 
yellow, finally a light brown when old and dry. The pri- 
mary conidia are hyaline, obovate, and measure 4p to 5u 
by 1p to 2u (pl. 9, f. 7). 
In cultures on rice and potato tubes tall Anthina-like, 
sterile, branching stalks, or stromatal outgrowths of a 
light brown color from 1 mm. to 4 mm. in height, are 
formed. These are very plainly abortive fruiting organs. 
Graphium album (Corda) Sace. 
A species of Graphium was found growing on the wood 
of thebeech, Fagus atropunicea (Marsh.) Sudworth. This 
discolored the wood a brown color. It was found to be a 
species resembling G‘. aureum, but sufficiently distinct to 
be separated from the latter species. A culture was sent 
to Mrs. Flora Patterson, Mycologist of the Bureau of Plant 
Industry, Washington, D. C., who identified the fungus as 
probably Graphium album (Corda) Sacc., a species which
