24s PUCCINIA 



^Ecidia od Gentaurea nigra, May and .June: undo- and 

 beleutospores on Carex armaria, July — April. Very rare; on 

 the sea-shore, Hemsby, Norfolk. (Fig. 191.) 



It has not been found anywhere else: but in all probability it could 



fairly be regarded as merely a well-marked biological race -a- mutation <>f 



/■. Schoeleriana (q.v.). Plowright's suggestion that it is identical with 



luistipes Rost. seems less likely, but it is closely allied to P. Caricis- 



montanae Fisch.

JZcidiospores. ^Ecidia amphigenous or on the stems, seated 

 on paler spots, scattered or in clusters, cup-shaped, whitish- 

 yellow, with torn margin; spores delicately verruculose, pale- 

 orange, 16 — 22 ll. 



('li'i/nspores. Sori on extensive pale spots, scattered, mi- 

 nute, oblong or linear, reddish-brown; spores subglobose or 

 ovate, irregular very delicately echinulate, yellowish-brown, 

 22-30x16— 22 ll. 



Teleutospores. Sori oblong, ^ — 1 mm. long, covered for a 

 long time by the epidermis which at length splits, pulvinate, 

 black ; spores subclavate, rounded or truncate above, rarely 

 hooded, thickened (up to 8/i), gently constricted, tapering 

 downwards, smooth, brown, 40 — 60 x 18 — 24 m ; pedicels short, 

 hyaline ; a few mesospores occasionally intermixed. 



Jv'idia on Aster Tripolium, June, July ; uredo- and teleu- 

 tospores on Carex extensa, August — June. Rare; Wells, 

 Norfolk. 



The life-history of this species was worked out by Plowright in 1888 ; 

 it has hardly been found elsewhere except in Istria.
