is partially bleached so that a longitudinal section shows dull 

 white blotches which indicate the presence of the fungus. 



Sphceria sabalicola E. and M. — Gregarious or scattered, perithe- 

 cia coriaceous with rather thick walls, about }{ mill, diam., cov- 

 ered by the epidermis which is raised into little obtusely conic 

 projections around which the surface of the matrix is of a tawny 

 colqr; asci clavate-cylindrical, 57 x 8 p-. Sporidia biseriate, ob- 

 long, 3-septate, brown, about 11 x l x A l u 



Sphceria sabalensioides E. and M— Perithecia scattered, min- 

 ute, % mill, diam., globose, covered, the short ostiolum barely 

 piercing the epidermis and visible under the lens as a small black 

 dot; asci 75-80 x 7 l A~9 ■"- Paraphyses none; sporidia biseriate, 

 elliptic-fusiform, appendiculate, yellowish, with a gelatinous en- 

 velop, 13-15 x 3>2-3-K /'• The short filiform appendages at 

 each end of the sporidia are soon absorbed. 



Sphceria sabalensis Cke., to which this is closely allied, has 

 much longer sporidia (50 ,«-.). 



To the above described species, which appear to be quite dis- 

 tinct from any of the species on Sabal published by Berkeley 

 'and Cooke, may be added : 



Cercospora mahicola E. and M. (N. A. F. No. 821).— Amphi- 

 genous, minutely tufted on withered spots in the leaf; hyphae 

 gray, nodulose, sparingly branched, 90-1 14 tu high ; conidia ter- 

 minal, narrow cylindrical or attenuated above, 5-7-septate, 75~95 

 ;>. long. Differs from C. malvarum Sacc, in its shorter hyphae 

 and conidia, duller color and orbicular spots.— J. B. Ellis and Dry^^ 

 Geo. Martin.

 center, with a definite dark brown or nearly black raised border 

 around which the leaf is stained purplish brown ; hyphae fascicu-
