A NEW VOLUTELLA. 
reddish-brown spores after the manner of a Melunconium; spores ellipti¬ 
cal, scarcely constricted, minutely granular-roughened, mostly rounded 
at both ends, scarcely thickened at the apex, 22—30 x 16—20 p. On very 
short pedicels. 
Puccinia nuda, E. & E.—On leaves of Arnica foliosa, Falcon 
Y r alley, Wash. Terr., July, 1885. W. X. Suksdorf, No. 200. 
III. Sori amphigenous, scattered or gregarious, round, black, about 
one millim. in diam., color of the leaf around the sori pale yellowish ; 
spores oblong-elliptical or oblong-clavate, slightly constricted at the sep¬ 
tum, strongly thickened at the apex, with a distinct, subhyaline, mostly 
oblique papilla, smooth, 35—45 x 19—22 p, pale at first but finally becom¬ 
ing quite dark, especially above, and then the upper cell becomes broader 
and the apex more obtuse ; pedicels 90—115 P long; a few spores with¬ 
out septa 25 x 22 /*, obovate, on long pedicels, were seen mingled with the 
others; also a few uredo spores globose, 25—30 p in diam., smooth or 
nearly so and without pedicels were seen in the same sori with the teleu- 
tospores. We have not seen Puccinia arnicalis , Pk., which was on Arnica 
cor difolia, from Colorado, and is said to have the “sori clustered, crowded 
or confluent, reddish-brown” and the teleutospores “scarcely constricted, 
minutely roughened” and the pedicel very short—characters which would 
seem to separate it from the Washington Territory specimens ; nor does 
it seem properly referable to P. Tanaceti , to which it bears a general 
resemblance.

BY A. B. LiANGLOIS. 
Volutella Ellisii, Langlois.—Sporodochia sessile, hemispheric, of 
delicate rose color, I —i millim. in diam.; hairs 80—100 x 3—4 P, hyaline, 
continuous, arising from the margin and from the whole surface of the 
membranaceous receptacle; conidia oblong, 6—10 x 21—3 p, curvulate, 
obscurely guttulate ; sporopliores bacilliform, 18—20 x 3 p. 
(Sporodochiis sessilibus, hemisphericis, loete roseis. 4—4 millim. latis; 
setulis 80—100 x 3—4 p, erectis, hyalinis, continuis ex margine vel toto 
membranaceo receptaculo assurgentibus ; conidiis oblongis, 6—10 x 24—3 
P, curvulis, obscure guttulatis ; sporophoris bacillaribus, 18—20 x 3 p, in 
culmis, vaginis foliis mortui graminum ex genere panicum principoliter, 
ad loca humida et umbrosa.) 
A very attractive little fungus, on dead pieces of grass, particularly 
of the genus Panicum , lying on damp ground, partially in shade. Pointea’ 
lallache, La.(No.l000.) The long, white bristles seem to be very fragile and 
to fall away easily. This volutella seems to be intermediate between V. 
Anindinis , Desm., and V. Gerry ana, Sacc., differing from both in its 
hemispheric sporodochia and in its conidia of intermediate size.
