523] MELIOLA IN PORTO RICO — STEVENS IS 



'15, 8083. Dee. 30, '13, 6563. Rosario, No. 4810. Marieao, July 19, 

 '15, 8784, 9001. 



The type was collected near Mayaguez by Heller, No. 4358, in 1900. 

 A specimen from the Bronx Garden, No. 6258, determined by Earle, 

 shows the capitate hyphopodia to be almost exclusively opposite. Al- 

 though this character is not mentioned by Earle in his description it 

 appears to me to be the most distinctive feature of the species. The 

 perithecia instead of being * ' few, 2-4, ' ' as described, are very numerous, 

 20+ per colony. The forward angling of the hyphopodia appears to 

 me to be a variable character. 



This fungus frequently grows upon the same leaf with M. clavulata 

 which it resembles very closely, with the exception of the setal tips 

 and the arrangement of the capitate hyphopodia. 



79. Meliola guareae Speg. 



Ann. d. Mus. Nac. de., Buenos Aires, 23 : 42, 1912. 

 On Guarea trichUioides L. 



Las Marias, July 10, '15, 8166 (type). Dos Bocas, below Utuado, 

 July 8, '15, 8096. Monte de Oro, Dec. 3, '13, 5737. Adjuntas, Nov. 22, 

 '13, 4971. Jajome Alto, Dec. 3, '13, 5691. Mayaguez Mesa, June 25, 

 '15, 7464. Usually associated with M. guareicola but on the lower side 

 of the leaves. 



These specimens differ from the type, which was sent to me by 

 Dr. Spegazzini, in that they have larger hyphopodia, more abundant 

 setae, and in minor colony characters, especially in density of growth. 

 The setae with forked tips are rare and the fact that this character was 

 not mentioned by Spegazzini is not significant. 



80. Meliola magnoliae sp. nov. 



Colonies hypophyllous, irregular, 3-20 mm. in diam., black. My- 

 celium forming a very loose network of threads, 7/* in diameter. 



Capitate hyphopodia alternate or irregular, distant, about 45/i 

 apart, head cell cylindrical, very little thicker than the stalk cell, 

 straight or somewhat curved, obtuse, the basal cell about 7/u. long. 



Mucronate hyphopodia opposite or irregular, almost cylindrical to 

 slightly bottle-shaped, 20/t long. Perithecial setae none. Mycelial setae 

 few, about 700/* long, straight or slightly curved, opaque. Tip acute, 

 simple or occasionally forked, with short teeth. 



Perithecia 200/i, in diam., slightly rough with rounded protuber- 

 ances, ostiole none. Asci soon evanescent; ascospores 4-septate, dark 

 brown, very strongly constricted, obtuse, 51 x 20/t.
