238 BULLETIN OF THE BUSSEY INSTITUTION. 
Lamit and Ram. Urtice of Fuckel, growing on Ozxalis acetosella at 
Eastport, in September, 1877, where it seemed to be common. 
UsTILAGINE&. — There has been received from Professor C. E. 
Bessey of Ames, Iowa, some interesting members of this order: viz., 
Thecaphora aterrima, Tul., on an undetermined species of Carex, So- 
rosportum bullatum, Schroeter, on Panicum Crus-Galli and Ustilago 
neglecta, Niessl., on Setaria glauca. With regard to the onion-smut 
described in the Mass. Agric. Report for 1877, opinions vary. In 
an article by Prof. Fischer von Waldheim, entitled “ Les Ustilaginées 
et leurs Plantes Nourricieres,” Urocystis Cepule is kept distinct from 
U. magica, Pass., and U. Colchici, Tul. Schroeter * states that he 
found specimens of U. Colchict on onion, in the herbarium at Stras- 
burg, and considers that U. magica is not distinct. He remarks that 
the Urocystis on onion in America has not been described, which would 
indicate that his article must have gone to press before the publication 
of the description in the Mass. Agric. Report. In the last number 
of the “ Bulletin,” we stated that U. Oepule and U. magica seemed 
identical, but differed from U. Oolchici. The difference, though slight, 
seemed constant, and how far it depends on the different texture of the 
foster-plants must be settled by cultures. 
Urepine&. In the present list the Roestelie and Podisomata are 
kept distinct. As the views of the writer with regard to the two 
genera are stated fully in another paper, in the present list it was . 
thought best to retain arbitrarily the specific names generally adopted 
in this country. Of species growing on coniferous trees, there occurred 
on young seedlings of Pinus ponderosa cultivated at the Bussey an 
interesting form of Peridermium. 'The disease showed itself in the 
latter part of May, covering the stems of a great part of the plants 
under cultivation. The form was that known in Europe under the 
name of Peridermiwm Pini var. corticola, which is fully described by 
Hartig.t In the specimens growing at the Bussey, no spermagonia 
were noticed. We have received the same species from Mr. J. B. 
Ellis, growing on pines near Newfield, N. J. In the Curtis collection 
are specimens from Santee River, S. C., collected by Ravenel, and 
from Alabama, collected by Peters (1242). The name attached to 
the above-named specimens is Pertdermiwm Pini but within the last
