State Musgum oF NATURAL History. 27 
in. long, generally containing a single large nucleus. Dead bark of 
choke cherry, Prunus Virginiana, Center. June. This species 
is closely related to M, intermedium, from which it is distinguished by 
its paler, smaller spores and especially by its distinct white stroma. 
In. M. intermedium the stroma is obsolete or merely cortical. It also 
approaches J/. effusum Cd. 
Torula uniformis, 7. sy. (Plate 1, figs. 11-13.) Flocci cespitose, 
erect, parallel or slightly diverging, nearly straight and uniform in di- 
ameter, .0012 in. to .003 in. long, black or blackish-brown, the articu- 
lations subquadrate, uninucleate, not easily separating, about .00016 
in. broad and long. Dead bark of maple. Quaker Street. June. 
The flocci are slightly united at their bases, and when pressed under 
the cover of the microscope slide they separate into groups of two to 
six or more, and look then very much like a species of Speira or Syn- 
phragmidium. ‘The species differs from TZ. splendens in its more 
slender flocci, which also are not narrowed above. 
Synphragmidium effusum, 7. sp. (Plate 1, figs. 6-10.) Effused, 
forming a dense velvety black stratum ; strings of spores moniliform, 
colored, sometimes paler at the tips, united at their bases into groups 
of three or more, either with or without a short common pedicel, at 
first laterally adherent throughout their length, .0016 in. to .003 in. 
long, .0002 in. to .0003 in. broad, the groups .0005 in, to .0011 in. 
broad, the cells about as long as broad. Decaying maple wood. 
Verona. Aug. 
I have not been able to detect any membrane investing the groups 
of spore threads, but its absence may be due to the age of the speci- 
mens. In every other respect the characters of the genus are present. 
The species is readily distinguished from S. AKuwmmeri by its effused 
character. The preceding species, Torula uniformis, strongly re- 
sembles this in its spore threads, which are united at the base, but I 
find no common pedicel to the groups. It forms a beautiful connect- 
ing link between Jorula and Synphragmidium. 
Gymnosporium variabile, 2. sp. Flocci sparse, branched, paler than 
the spores; spores abundant, variable, globose, elliptical, oblong or 
fusiform, purplish-brown, .0005 in. to .0012 in. long, .0005 in. to 
.00055 in. broad, forming effused pulverulent patches. Under sur- 
face of decaying wood lying on the ground. Albany. May. The 
species is related to G. fudvum from which it differs in its darker, 
purplish-brown color and in its smoother and more variable spores. 
Puccinia Ellisiana Thum. Living and languishing leaves of An- 
dropogon scoparius and A. furcatus. Buffalo. Clinton. Center. 
Sept. and Oct. This is apparently Puecinia Andropogi Schw., but 
that name is badly formed, nor can it be corrected without interfering 
with Puccinia Andropogonis Fckl. I have therefore adopted the later 
name. 
Protomyces fuscus, x. sp. Spots irregular, determinate, blackish- 
brown or grayish-brown, often marginal; spores immersed in the 
-tissues of the leaf, globose, colored, .0016 in. to .0024 in. in diameter, 
with a thick epispore. Living leaves of liverwort, Hepatica acutiloba 
Helderberg mountains. July. This species differs from P. macros- 
porus in the darker color of the spores and in its darker definite spots.
