those of P. dispersa being brown, scattered, and few. ‘The promy- 
celium spores and germ-tubes of P. dispersa are colourless. 
310. Puccinia glumarum Schum. 
Acidiospores unknown. 
Uredospores Sori *5-1 mm. long by *3-°4 mm. wide linear, on 
the leaves in long confluent colonies seated upon yellow discoloured 
spots often 70 mm. long, very destructive inside the paleze and upon 
the immature kernels. Soricitron yellow. Spores spherical or shortly 
elliptic echinulate, yellow 25-30 p. 
Teleutospores Sori covered by the epidermis on the sheaths and stems 
in long fine brown or black lines, on the inner side of the pale more 
scattered. Each spore group is divided in numerous compartments, 
each of which is surrounded by a circle of dark brown, over-arching 
paraphyses. Spores shortly pedicellate, generally clavate unsymmetrical, 
apex flattened or with one or two bluntly pointed laternal projecting 
continuations. Upper cell 30-40 x 16-25 nw, lower 9-12 mw broad. 
Spores germinating in autumn. Contents of the promycelium yellow. 
On wheat, barley, rye, and many grasses. 
Synonyms. Puccinia rubigo-vera D.C. P. strieformis Westd.

Readily distinguished by the naked eye from P. dispersa while in 
the uredo stage from the fact that the spores are yellow, extremely 
abundant, and seated upon large elongated yellow spots, which often 
occupy half the blade. This is the early spring-rust. On the foliage 
it does but little harm in this country, but when it establishes itself, 
as it often does, in. the chaff and on the wheat kernels, it seriously 
damages the latter. 
311. Melampsora vernalis Niessl. Teleutospores in small, irregular, 
yellow brown, mostly densely crowded sori. Spores oblong or clavate 
unilocular, intercellular, as much as 45 p long, yellowish brown.

312. Melampsora galii Link. Uredospores sori minute, round, pustu-

apex perforate, spores elliptical or ovoid 14-2 5X 10-17 p, aculeolate,
