This makes Peck’s specific name in the present case untenable, 
unless it should be found that the species are the same. Norton 
reports the germination of the spores. Literature: 72, 129. 
Sorosporium Eriochloae Griff. 
Sorosporium Eriochloae Griff., Bull. Torr. Bot. Club, 31: 84. 1904. 
Sori in ovaries, oblong, about 2—3 mm. in length, more or less 
concealed by the enveloping glumes, with a conspicuous whitish 
false membrane that ruptures in lobes from the apex disclosing a 
blackish somewhat agglutinated spore mass and a small columella; 
sterile cells of false membrane adhering together rather firmly, 
chiefly cubical to 2-3 times as long as broad, occasionally more 
rounded; spore balls rather irregular but chiefly ovoid to subspheri- 
cal, soon separating into spores, usually 60-100 fx in length; spores 
somewhat agglutinated, dark reddish brown, ovoid to subspherical 
or occasionally polyhedral, smooth or minutely verruculose, 11—16 /x 
in length. 
Host: Eriocliloa punctata , Ariz. (type). 
This species was collected by Griffiths in the Santa Rita Moun¬ 
tains of Arizona, where it is a common smut. In the older sori, the 
spore balls are often very indefinite but in the younger parts they 
seem to be constant and characteristic; otherwise the species would 
come under Sphacelotheca.
