ARTHUR: NEW SPECIES OF UREDINEAE—XV 53 
state which might belong to any one of several genera,”” may be 
dismissed as untrue, for he himself points out further along 
on the same page, that “the markings on the spores {uredinio- 
spores] of this and the allied species are more often of the nature 
of mere roughnesses than like the neat and regular higher types 
(Puccinia, etc.).’’ He described and figures three British species 
of the genus, and has since added two more, without a word 
describing teliospores, which in fact are scarcely known and 
wholly negligible taxonomically, the urediniospores being suf- 
ficient to separate the species, and the genus as well. 
Milesia australis nom. nov. 
Uredo Blechni Diet. & Neg. Bot. Jahrb. 22: 358. 1896. Not 
Milesia Blechni Arth. 1922. 
The urediniospores are much smaller and thinner-walled 
than in Milesia Scolopendrii of Europe. The original collection 
of Uredo Blechni Diet. & Neg. was made near Concepcion, Peru, 
in May, 1896, on Blechnum hastatum. The same fungus on 
Lygodium polymorphum from Trinidad, Thaxter 45, was er- 
roneously listed by the writer (Bot. Gaz. 73: 61. 1922) under 
the name Milesia Blechni, a synonym of M. Scolopendrii, and a 
name belonging to a European species, not yet found on the 
Western Hemisphere. 
Chrysopsora Cestri (Diet. & Henn.) comb. nov. 
Puccinia Cestri Diet. & Henn.; P. Henn. Hedwigia 41: 295. 
This characteristic species has been known for more than a 
couple of decades, the type collection being from Brazil, but 
without being recognized as belonging to the genus Chrysopsora. 
The spores are much smaller than in C. Gynoxidis Lagerh., the 
only species heretofore assigned to the genus, but the germination 
shows the same peculiar Coleosporiaceous character. The 
species has now been found in Central America, having been 
collected in Dept. Bocas del Tora, Panama, on C. aurantiacum 
Lindl., September 1920, by M. A. Carleton, no. 35, and in same 
region, June 1921, by John R. Johnston, no. 2555. It was also 
collected on Cestrum sp. at Estrella, Costa Rica, in 1920, by 
John R. Johnston, no. 7201.
