mycelium, however, in such cultures, retains its vitality for months 
through the concentration of the protoplasm in definite portions of 
the hyphae; without, as far as I have observed, producing the well 
differentiated chlamydospores which have been described in the other 
species. . 
The fertile hyphae (fig. 1) which are very variable in size, often 
reach a height of from five to six mm., and generally originate from 
the rapid enlargement of a slender branch from a vegetative hypha. 
They are whitish, with a more or less distinct purplish iridescence, 
and the inflated extremity may rarely bear the conidia directly, as in 
Rhopalomyces, but usually gives rise to from three or four to a dozen 
or more ramuli. The latter are commonly simple, but very frequently 
branched as in fig. 3, the tips swelling abruptly and forming second- 
ary heads ; the surfaces of which, by a process of budding (fig. 2), 
become covered by a layer of densely crowded spores (fig. 5). ‘The 
conidia, are rich purplish brown, appearing almost black in the mass, 
. varying from oblong to short or long oval or elliptical in outline, and 
are marked by longitudinal striations which anastomose sparingly. 
'The base of the spore is furnished with a more or less conspicuous, 
short, tongue-like, hyaline appendage; which is merely an adherent 
portion of the pedicel of attachment. The spores measure in well 
developed heads about 20 X 10,4, though larger, and frequently 
much smaller ones are found. They are caducous at maturity, leav- 
ing the sporiferous head beset with short spinulose projections, with 
corresponding faint areolations as in Rhopalomyces. Germination 
takes place very rapidly in water, or in nutrients; the copious myce- 
lium developing at once. 
The fate of the sporigerous ramuli and heads appears to be an 
important point in distinguishing the species of the genus, which 
owes its name to the fact that in the type, C. zufundibulifera, the 
branchlet and the lower half of the sporiferous head become some- 
what indurated, through the thickening of the membrane. The dis- 
tal portion of the head being thin-walled, shrivels, and the persistent 
branchlet thus has the form of a little funnel. In C. Simonsii, the 
second Indian species, there is no such modification; but although 
the branchlet shrivels, it is more or less persistent. In our species, 
however, the ramuli not only shrivel, but are caducous at about the 
same time that the spores fall from their attachments, and leave the 
primary head (fig. 4) clathrate through the presence of rounded ori- 
fices corresponding to their insertions.
