Entyloma arnicalis Ell. & Ev.,i N. A. Fungi, 3136. 1894. 
Exsiccad : Entyloma arnicalis Ell. & Ev. n. sp ., on Arnica Chamissonis , 
Ell. & Ev., N. A. Fungi, 3136, Ell. & Ev., Fungi Col., 540. 
Sori in leaves, forming reddish brown subcircular or angular areas, 
prominent on upper surface, 3-8 mm. in diameter, distinct or often 
llling intervening tissue and thus forming an extended dead area ; 
spores yellowish to chestnut brown, rather uniform, chiefly subspher- 
ical or spherical, often with evidence of gelatinous envelope which 
in some cases forms conspicuous papillae on the rather thick spore 
wall, chiefly 13-17 /x in diameter; conidia forming a slight hypophyl- 
lous growth in center of area, chiefly linear lanceolate, often slightly 
curved at upper end, about 18-28 /x x 3 /x. 
Hosts : Arnica Chamissonis , Wash, (type) ; A. corclifolia, Ida. • 
A. latifolia , Wash. 
. While this species approaches Entyloma Calendulae of Europe, 
it seems to possess larger and usually darker spores. The specimen 
from Washington on Arnica latifolia has conspicuous hyaline papil- 
ae on many of the spores, evidently developed from the gelatinous 
hyphae covering the spores; the other specimens show these only 
occasionally and not so prominently. Ellis and Everhart give their 
species of Ramularia arnicalis as the conidial stage of this fungus. 
The spores have not been germinated. 
Entyloma guaraniticum Speg. 
Entyloma guaraniticum Speg., Fungi Guar., pug. 1 : 65. 1886. 
Son in leaves, subcircular, lightish or eventually dark colored 
usually separate, often thickened and concavo-convex, 2-6 mm. in 
tameter; spores hyaline to light yellow, more or less adhering in 
masses or uniserial rows, subspherical to oblong or more irregular 
provided with prominent gelatinous envelope which is not always 
distinct from cell wall, 11-20 ^ in length.
