190 Artuur: NEw sPECIES oF UrEDINEAE—XIV 
In the twelfth article of this series, under Puccinia offuscata 
(Bull. Torrey Club 47: 469. 1920), the name Uredo Zorniae 
Dietel (Hedwigia 38: 257. 1899) should have been given as a 
synonym. This name was applied to Ule’s 2296 from Brazil. 
Although pyenia have not been seen yet there is circumstantial 
evidence to indicate that no aecia are produced, and therefore 
the species is probably a Bullaria, and should be called B. 
Zorniae (Dietel) comb. nov. It is a species of the New World, 
to which the name Puccinia Zorniae McAlpine does not apply. 
In the same article, under Pucciniastrum americanum(Bull. 
Torrey Club 47: 468. 1920), Rubus occidentalis was erroneously 
given as a host for this species. The error was called to my 
attention by Dr. J. J. Davis of the University of Wisconsin, 
and was confirmed by subsequent examination under the 
microscope. The type of P. arcticum americanum Farl.is on Rubus 
neglectus Peck, collected at Bussey, near Cambridge, Massachu- 
setts. This collection is first mentioned in the original article 
by Farlow (Rhodora 10: 16. 1908) as on R. occidentalis near 
Cambridge, but later in the article is referred to as on R. neglectus, 
Bussey, October, 1875. The correction in the name of the host 
is credited to M. L. Fernald. I have been able to ascertain these 
facts through the assistance of Dr. R. Thaxter, who has carefully 
examined the original material in the Farlow Herbarium.
