152 Puccinia Com-positae. 



Aecidiospores sub-globose to angular, orange-yellow, smooth, 

 showing up to 4 germ-pores on one face, 16-19 X 12-13ju or 

 14-16 ^u diam. 



III. Teleutosori black to blackish-brown, long covered by leaden 

 epidermis, pulvinate, compact, round to elongated, sometimes 

 confluent, 1-1 ^ mm. long. 



Teleutospores clavate, dark brown, particularly in upper cell, 

 slightly constricted at septum, smooth, 40-57 X 17-24 ju, average 

 45 X 22 p ; upper cell rounded, scoop-shaped, sometimes truncate 

 and thickened at apex (up to 1 1 p) : lower cell yellowish brown, 

 attenuated towards base ; pedicels persistent, tinted to hyaline, 

 up to 35 p long and sometimes 10 p broad. 



X. Mesospores common, elongated, elliptical to oblong, generally paler 

 than teleutospore, thickened at apex, and generally scoop-shaped, 

 28-35 x 13-16 p.

The teleutosori and teleutospores generally resemble those of P. 

 tasmanica Diet., but they are not intermixed with aecidia. They both be- 

 long, however, to the same general type.

 cup-shaped, with whitish, reflexed, laciniate margins. 



Aecidiospores subglobose to polygonal, finely echinulate, 13-14/ 

 diam., or 13-15 x 12 p. 



III. Teleutosori minute, black, erumpent, gregarious, comp* 



Teleutospores dark chestnut-brown, oblong to elongated oblong 



clavate, smooth, constricted at septum, rounded or bluntly poinl 



and thickened at apex (up to 9 p), 37-50 X 18-28 p, avera, 



38-40 x 18-20^u; pedicel hyaline, persistent, generally taperii 



towards base, about 30 p. long, or shorter than spore. 



X. Mesospores not uncommon, similarly coloured to teleutospores, 



stalked, obovoid to ellipsoid, rounded or bluntly pointed 



thickened at apex (6-8 p), 28-37 x 15-18 p.

The teleutospores generally resemble those of P. vittadiniae, but they 

 longer on the average.
