‘This fungus forms long discolored lines or patches on the leaves, closely 
resembling “those formed by Ur ocystis Agropyri and Urocystis occulta. The 
spores in our specimens, as well as in those received from Europe under this 
name, are quite uniformily globose, not obovate as given in the description. — 
‘They are generally .0004'—.0006’ in diameter, but occasionally they attain a % 
diameter of .001'. I am not aware that this species has been before detected 
in this country. 
MASssosPorRA, gen. nov. 
Spores numerous, loosely adhering together and forming a pulverulent mass 
without any evident peridium. Insecticolous. 
This is a peculiar genus, apparently belonging to the Coniomycetes, but its 2g 
affinities are doubtful.

mis - Spore mass occupying the abdominal cavity, whitish or pale cream-color, at 
. length exposed by the falling away of the terminal rings of the abdomen; _ 
— spores subglobose or broadly elliptical, granular within, sometimes containing 
si one to three unequal nucleoli or oil globules, .00065'-.00085° in diameter. 
In the abdomen of the “Sev yenteen-year Locust,” Cicada septendecim.

This is a singular fungus, unlike any other known to me. In its early 
stage it is wholly concealed in the body of the insect, but just before, or soon —

Mid after the death of the insect, the terminal rings of the abdomen fall away, 
ee revealing the pulverulent mass of spores within, which, by a superficial 
observer, might easily be mistaken for a lump of pale-yellow or whitish clay. 
[have not been able to detect any proper peridium, nor does any seem to be 
Pa necessary, the walls of the abdomen answering as a substitute. In one or 
a: two examples, the spore mass was less fully developed, and of a brighter — 
ae color. The spores, in this case, were much larger, being .0015/—.002/ in 
Pe, . diameter, with the epispore roughly reticulated. This is probably an earlier — 
g condition of the same species, and is another indication that the proper posi- —~ 
He. tion of the fungus is among the Coniomycetes, where there are several genera, 
ee with spores of two orders. ‘The position of the genus, as it seems to me, is In 
4 the vicinity of the genus Protomyces, which has the spores developed in the 
4 living tissues of plants, as this has in the tissues of insects. This fungus is 
: noticed, but not named, in Smithsonian Contributions, Vol. v, p. 53.

2 Stem very slender, elongated, glabrous, lemon-yellow, one to one and a 
4 half inches high, divided above into a few irregular branches, which are ee 
wholly covered by the white mealy coating of conidia; conidia oblong-ellip- 
e tical, .00016’—.0002’ long.

This is probably only a condition of some Torrubia; but, as it does not 
agree with any described form, I have thought best to designate it, for the 
present, by a name of its own.
