513] MELIOLA IK PORTO RICO — STEVENS 45 



hyphopodia alternate or opposite, wedge to bottle-shaped, 18 x Ifx. Peri- 

 thecial setae none. Mycelial setae few, straight or slightly curved, 400 x 

 Ifx, dark throughout, tip acute. 



Perithecia llO-lSO/x, slightly rough with rounded protuberances. 

 Asci 2-spored, soon evanescent; ascospores 4-septate, brown, cylindrical, 

 elliptical, distinctly thicker at the middle than toward the ends, strongly 

 constricted, obtuse, 41-44 x ISju,.

Guayanilla, July 14, '15, 8549 (type). Quebradillas, June 20, '15, 

 7265. 



This species differs from 31. omphitricha in shape of the capitate 

 hyphopodia and spores and from 31. hrasilicnsis in character of spores 

 and setae. 



60. Meliola ocoteicola sp. nov. 



Colonies amphigenous, irregular, 3-10 mm. in diam., confluent. 

 Mycelium forming a rather loose network of threads, branches mostly 

 opposite, 7ju, in diameter. 



Capitate hyphopodia alternate, not crowded, about 30/i. apart, cylin- 

 drical, head cell scarcely thicker than the stalk, apex obtuse, the basal 

 cell very short. Mucronate hyphopodia few and scattered, usually oppo- 

 site, conical to bottle-shaped, 20 x 6/x. Perithecial setae none. Mycelial 

 setae few, straight or slightly curved, 300-350(U,, dark, tip acute. 



Perithecia 150ja, ostiole none. Asci soon evanescent ; ascospores 4- 

 septate, brown, strongly constricted, obtuse, 40 x 17/i..

Mayaguez, June 29, '15, 756^0 (type). Monte Alegrillo, near Mari- 

 cao, Nov. 14, '13, 4762. 



On Chrijsoplxiillum sp. 



Monte Alegrillo, Nov. 14, '13, 4731 (type), Nov. 18, '13, 4519. 



In characters of the capitate hyphopodia this is similar to 31. mag- 

 noliae but is still clearly distinct from that form. 



Nos. 4579 and 4731 on Chrysophyllum present in the hypophyllous 

 colonies a peculiar variation, in that the mycelium is exceedingly crooked 

 and irregular. These represent, perhaps, a distinct species, but on ac- 

 count of the general resemblance of the capitate hj^phopodia and the 

 setae to the other form of Chrysoi)hyllum, they are regarded as co-spe- 

 cific with it. 



61. Meliola paullinl\e sp. nov. 



Colonies black, setose, circular, epiphyllous, 3-8 mm. in diam. My-
