 tuse, 34 X 14/A. 



On Chamaecrista granulata (Urb.) Britt. Fig. 24. 



Mona Island, Dec. 20, '13, 6113 (type). 



This differs from all other forms in this section in the extremely 

 thin setae. 



28. Meliola rectangularis sp. nov. 



Colonies epiphyllous, circular to irregular, 1-10 mm. in diam. Myce- 

 lium forming a loose network of threads with opposite branches which 

 usually form right angles at the point of origin, Ifx, in diameter. 



Capitate hyphopodia alternate, about 25//, apart, cylindrical to 

 ovoid, head cell 17 x 10/a, scarcely thicker than the stalk cell, the basal 

 cell 3-5/x,. Mucronate hyphopodia alternate or opposite, conical to nar- 

 rowly bottle-shaped, the neck narrow, 20 x 6/x. Mycelial setae none. 

 Perithecial setae few, short, 80/a or less, opaque, straight or slightly 

 curved. Tip obtuse. 



Perithecia 170/x. Asci soon evanescent; ascospores 4-septate, brown, 

 slightly constricted, obtuse, 38 x 14/*. 



On Coccolohis laurifolia, Jacq. Fig. 25. 



Arecibo-Lares Road, June 21, '15, 7292 (type). 



This species is chiefly characterized by its poorly differentiated hy- 

 phopodia and the right-angled branching. In the first, of these charac- 

 ters it approaches M. magnoliae but is quite distinct from that form.

 opposite and at right arigles. 



Capitate hyphopodia alternate, not crowded, 1 per cell, cells about 

 20/1 long, head cell irregularly globular, angular, 17/t in diameter, the 

 basal cell 2-6/i long. Mucronate hyphopodia not seen. IMycelial setae 

 none. Perithecial setae few, straight or slightly curved, 120 x 7/t. Tip 

 obtuse, dark throughout.
