On Magnolia portoricensis Bello. Fig. 50, 



Monte Alegrillo, near Maricao, Nov. 14, '13, 4738 (type). 



This species is remarkable for the slight differentiation of its capi- 

 tate and mucronate hyphopodia which differ from each other but little 

 and also very much resembles branches, though of determinate growth. 

 This is evidently one of the most primitive forms in the genus. 



81. Meliola smilacis sp. nov. 



Colonies amphigenous but more abundant above, circular, irregular, 

 2-4 mm. in diam. Mycelium not crooked, of medium density, branches 

 opposite. 



Capitate hyphopodia alternate, opposite or unilateral, head cell 

 cylindrical to globular, 14 x 11/x, stalk cell short, about 4jit. Mucronate 

 hyphododia rare, conical, neck short and tapering, or ampulliform with 

 neck longer. Mycelial setae abundant, about 500/a high, tapering, lOyu, 

 thick at base, apex obtuse, rarely bifid, pale, base opaque. 



Perithecial setae or appendages none. Perithecia about 200/x in 

 diam. Ostiole a mere thinning of the apical region. Asci soon evanes- 

 cent, short type. Spores 4-septate, but slightly constricted, ends ob- 

 tuse, 15 X llfjL. 

 On Smilax coriacea Spreng. 



Manati, Nov. 25, '13, 5261 (type). 

 On Smilax sp. indet. 



Jajome Alto, July 17, '15, 8429. 



The two hosts appear to be quite different but it is possible that the 

 latter specimen is a form of S. coriacea. 



This Meliola belongs to the group of 31. amphitricJia from which 

 it is distinguished by its ostiole, which is however, very difficult of ob- 

 servation, by the sometimes forked tips of the mycelial setae and by the 

 capitate hyphopodia. 



82. Meliola helleri Earle 



Bull. N. Y. Bot. Gard. 3 : 307, 1905. 



The type is on an "unknown woody plant perhaps belonging to 

 the Myrtaceae", Heller No. 6251, 3 miles west of Ponce, Dec. 9, 1902. 



The setae in the cotype specimen which I examined were more fre- 

 quently simple than forked as called for in the description. 

 On Eugenia stahlii (Kiaer.) K. and Urb. 



Luquillo Forest, Dec. 4, '13, 5343. El Alto de la Bandera, July 15, 

 '15, 8665. Jajome Alto, July 17, '15, 8436. 



The specimens are much overgrown by parasites. Setae were seen 

 upon one specimen, but all were simple.
