small, more or less inconspicuous, and sparingly developed. There 
are a number of basidiomycetous forms that produce bulbils as an 
imperfect condition. In a former contribution (6) the writer has 
referred to 4 such species, and in the present article 2 additional 
ones are described. The reddish orange color of the bulbil under 
consideration readily distinguished it from other species having 
clamp connections. The bulbils of P. nigra and P. anomala are 
dark brown or black, those of Corticium alutaceum chocolate brown, 
and those of Grandinia crustosa straw colored with conspicuous 
clamps. 
Samples of the fruiting bodies of Sporodesmium aurantiacum — 
B. and C., collected by Dr. THAXTER at Cranberry, North Carolina, 
in August 1889, were obtained from him for comparison with the 
bulbils of P. aurantiaca. As these structures were too old to 
germinate, a comparison of their mode of development could not 
be'made. The fruiting bodies of the two fungi resemble each other 
so closely in their general form, color, texture, etc., however, that 
there is little doubt but that they are identical. 
DEVELOPMENT OF BULBIL.—In common with many other bul- 
bils, those of P. aurantiaca begin by a short lateral branch coiling 
- up spirally. The early stages in the development, with some of the 
variations, are illustrated in figs. 25-38. During the process of - 
coiling, which seldom results in more than two turns, the individual 
cells comprising the primordium become well supplied with food 
material and often appear distended (figs. 26, 27, 29). From the 
cells composing the coil short branches are developed (figs. 27, 28, 
ay, 0); Thee secondary branches may twine about each other 
or they may enlarge, forming cells that resemble those ahteneirn oe 
_ by a process of gemmation in other bulbils. These short b a 
: and cells continue to be formed, sometimes on the concave side of ae
