Gibellula capillaris Morgan n. sp.—Stroma simple, capil¬ 
lary, flexuous, curved and coiled, fulvous, whitish at the summit; 
the base none or very short, almost the whole surface sporiferous. 
Hyphae longitudinal, very slender, fulvous, solidly packed to¬ 
gether and connate, at the surface giving off very short or minute 
sporiferous branchlets; the sporophores thick, obtuse, pellucid, 
each from its apex producing several spores in one or a few short 
chains, which are proliferously developed. Spores clavate, 
smooth, hyaline, 6-9 x 1-2 mic. 
Growing out of very small dead insects among the old leaves 
in woods; Preston, O., June 14, 1903. There are as many as a 
dozen growing out of one small insect, curved and coiled about it 
like a bundle of fine hairs. The stromata 5-8 mm. long, 40-60 
mic. in thickness; the sporophores scarcely longer than the spores 
but much thicker. 
CULTURES OF UREDINEAE IN 1904. * 1 
J. C. ARTHUR. 
The present article forms the fifth of a series of reports 2 by 
the author upon the cultures of plant rusts. They cover the years 
from 1899 to the present year inclusive. In these studies the grass 
and sedge rusts hold a prominent place, but some other heteroe- 
cious and a few autoecious rusts have been included. 
During the period when the cultures are in progress, the con¬ 
stant attention of one person is required to assort the material 
which is in germinating condition from that not yet ready to germ¬ 
inate, to sow the spores, to maintain a careful watch for the first 
appearance of the spermogonia and aecidia, and to keep the rec¬ 
ords with unimpeachable accuracy. At the beginning of the pres¬ 
ent season the Indiana Experiment Station established a cooper¬ 
ative agreement with the Bureau of Plant Industry of the U. S. 
Department of Agriculture to mutually assist in carrying on the 
annual culture work. Through the government assistance Mr. 
F. D. Kern, a senior student from the University of Iowa, recom¬ 
mended by Professor T. H. MacBride, was secured to take charge 
of the cultures. Mr. Kern proved an exceptionally able man for 
the position, having unusually keen and accurate powers of observ¬ 
ation, a retentive memory, and scholarly enthusiasm. Mr. Kern’s 
work extended through May, and a part of April and June.
