i. 712. McAlpine, Rusts of Australia, p. 116, pl. C, and fig. 28.

Klebahn, /.c. p. 239. Fischer, Ured. Schweiz, p. 359, f. 262. 
P. dispersa Erikss.; Marshall Ward, Ann. Bot. 1902, xvi. 233; 
Annal. Mycol. 1903, p. 132. Freeman, Ann. Bot. zbed. p. 487. 
Aeidium Symphyti and Al. Pulmonariae Thiim. 
Spermogones. Honey-coloured. 
Aicidiospores. Aicidia hypophyllous or on the petioles, 
sometimes even on the calyx, seated on large round or irregular 
spots which are purplish-brown and surrounded by a yellow 
zone, cup-shaped, with an incised revolute margin; spores 
verruculose, orange, 18—27 p. 
Fig. 199. P. bromina. a, teleutospores; b, a mesospore; c¢, paraphyses 
surrounding the teleuto-sori ; d, uredospores (empty); e, paraphysis in the 
uredo-sori. On Bromus sterilis. . 
Aicidia on Symphytum officinale; uredo- and teleutospores 
on many species of Bronwus, sometimes even on the inflorescence, 
teleutospores from June onwards. (Fig. 199.) 
The teleutospores germinate only after the winter’s rest ; Ward found 
germinable uredospores even in February and March; it has been proved 
that an ecidium on Pulmonaria montuna belongs to the same life-cycle. 
F. Miiller, E. 8. Freeman, and especially Marshall Ward, have investigated 
the Brown Rusts of the Bromes, and have discovered a wonderful series of 
inter-relations among them.
