218 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



undoubtedly identical with a widespread species, having telia on 

 Carcx and aecia on many Cichoriaceous hosts, but it has not been 

 reported by any other collector on Hierachim paniculatwm. The 

 species has generally been called Pucc'mia patruclis Arth., but 

 Schweinitz's specific name is much older and should therefore be 

 used, making the name P. hieraciata (Schw.) comb. nov. No other 

 collections of P. hieraciata, either of secial or telial stages, are 

 known with certainty east of Michigan and Indiana, but it is not im- 

 probable that the species occurs sparingly in the eastern mountains. 



*2869. 59. C. A. Erigeronatum, L.v.S., rather rare but ample on E. hetero- 

 phyllus, Bethlehem. 

 C. spots very large, 3'ellowish, rather thick. Pseudoperidia densely 

 and irregular^ scattered, elevated. Spores yellowish. 



Represented by the major part, 5.5 cm. in length, of two leaves, 

 2 and 3 cm. broad respectively, the smaller showing four groups of 

 ascia, and the larger many secia thickly and evenly grouped over 

 an area 2.5 cm. across, and also by an empty packet labelled inside 

 "^cidium Flosculosorum Salem," later added below "in Solidago, 

 Erigeron, Aster," and still later added above " Cseoma asteratum," 

 and finally " erigeronatum," and also labelled on the outside 

 " ^'Ecidium compositat Erigcronatwn LvS Bethl." 



The host, which has been compared with phanerogamic speci- 

 mens, is certainly Erigeron annuus Pers. (E. heterophyllus Muhl.), 

 and the rust is the common one on this host, being the aecial stage 

 of Puccinia Asterum (Schw.) Kern, and belonging to the physio- 

 logical race represented by the name Puccinia Caricis-Erigerontis 

 Arth., as proven by cultures. Schweinitz changed his name to 

 ^cidimn (Ccsoma) erigeronatum on page 309 of the same work. 



2870. 60. C. A. Asteratum, L.v.S., Syn. Car. 444, Lk. 143, common, especially 

 on A. paniculatus. Link does well to join with this C. Soli- 

 daginis, Syn. Car. 446, and C. Verbesinse, 445. But C. Helianthi 

 does not belong here. 

 (444. 15. [^cidium] Asterum Sz. 



A. efifuse, confluent, very delicate, pale, purplish, peridia aggre- 

 gated, immersed, spore-mass white. 



Here and there on leaves and stems of smooth leaved Asters. — 

 Spores rather large, vescicular, globose or oblong, simple.)
