in diameter. Asci soon evanescent; ascospores 4-septate, dark 

 brown, cylindrical, 50-55X18-20 )u, definitely constricted at the 

 septa. ■ 



On leaves of Cestrum species, Mayaguez, June 29, 1915, no. 7576 

 (type). 



This species is entirely distinct from M. gesnerii Stevens, which has also 

 been reported on this host. 



Meliola clusiae Stevens, 111. Biol. Monographs 2:75. 1916. 



On Clusia gundlachi Stahl, El Alto de la Bandera, July 15, 191 5, no. 8670. 

 Previously reported on Clusia rosea Jacq. 



Meliola bayamonensis, sp. nov. — Colonies hypophyllous, 2-5 

 mm. in diameter, mycelium a very loose network of threads; 

 branches alternate, hyphae dark, 4 m in diameter, wavy. 



Capitate hyphopodia alternate, 30-60 ju distant, the head cell 

 globose to oval, 8-10 n in diameter; the basal cell variable, 6-16 n 

 long. IMucronate h>^hopodia few, alternate, 14 ju long. Mycehal 

 setae none; perithecial setae 5-7, arising basally, decumbent, dark 

 brown to opaque, 225X4-5 M, apex acute. 



Perithecia scattered, 100-135 ju in diameter, rough, Asci soon 

 evanescent, ascospores 4-septate, 27-30X7 M, slightly constricted 

 at the septa. 



On Psychotria pubescens Sw., at Bayamon, February 19, 1913, no. 392 

 (type). 



This species is separated immediately from the variety described on the 

 same host by Stevens as M. glabra, var. psychotriae by the presence of peri- 

 thecial setae. It is also distinct from M. psychotriae Earle on account of its 

 remarkably looser habit, the characteristic waviness of the mycelium, its 

 lighter color, the shape of the capitate hyphopodia, and the strikingly short 

 basal cell. 



Meliola marcgraviae, sp. nov. — Colonies epiphyllous, irregular, 

 3-10 mm. in diameter, branching opposite, hyphae dark to opaque, 

 5-6 ju in diameter. 



Capitate hyphopodia alternate, 32 m distant, head-cell globose, 

 II M in diameter; basal cell short, 5 fx long. Mucronate hypho- 

 podia mostly opposite, but frequently alternate, flask-shaped, 

 12-14 jLt long. Mycelial and perithecial setae none.
