NATURAL HISTORY BULLPrjTX. 



So far as we can find. Curtis never published a description 

 of this species. It was first described by Professor Peck, 

 (1872. 23rd Rep. p. 57.), under the name of Puccinia acum- 

 inata Peck, but this name had ah'eady been used by Fuckel 

 ( 1869. Sy"i- M^'c. p. 55.) for a different Puccinia. It was 

 distributed in Thuemen. Mycotheca Universalis, No. 545, as 

 Puccinia porpliryrogcuita Curt. sec. Peck in litt. ad me. 



Spots orbicular, brown or purplish, often deeply depressed; 

 sori black, confluent, the larger ones forming a circle around 

 a free central space, surrounded by the ruptured epidermis; 

 spores oblong, strongly constricted, 16-20 by 48-56/^; apex 

 thickened, mostly acute; pedicel tinted, shorter than or equal- 

 ling the spore. Plate III., Fig. 14. 



Under pressure of the cover glass, the spores quite readil}' 

 separate at the septum. 



The acumination at the apex is quite often oblique, some- 

 times quite long and almost beak-like.
