517] MELIOLA IN PORTO RICO — STEVENS 49 



This species is distinguished from M. hrasiliensis by the shape of the 

 capitate hyphopodia and the bases of the setae. 



67. Meliola gymnanthicola sp. nov. 



Colonies epiphyllous, circular, 2-4 mm. in diam. Mycelium form- 

 ing a close network, l/x in diameter, branches mostly opposite and often 

 at right angles. 



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

 20fi long, head cell ovoid to nearly cylindrical, 17 x lO^n, the basal cell 

 2-3//, long. Mucronate hyphopodia alternate or opposite, conical to bot- 

 tle-shaped, irregular, 16-18 x 7/x. Perithecial setae none. Mycelial 

 setae scattered, slightly crooked, 300 x 7/i. Tip obtuse, dark. Perithecia 

 190/x, slightly rough. Asci soon evanescent ; ascospores 4-septate, brown, 

 very slightly constricted, obtuse, 37 x 17/t.

68. Meliola lucumae sp. nov. 



Colonies amphigenous, much larger below, irregularly circular, 

 2-10 mm. in diam., diffuse. Mycelium forming a loose network, Ifx. in 

 diameter, branches mostly opposite. 



Capitate hyphopodia alternate, distant, 1 per cell, cells about 35/* 

 long, head cell cylindrical or tapering slightly at each end, 17 x 7/a, 

 the basal cell 3/t long. Mucronate hyphopodia few, mostly opposite, 

 narrow-conic, about 20 x 4/t. Perithecial setae none. Mycelial setae 

 few slightly curved, 200-800 x 7/i, dark throughout. Tip obtuse. 



Perithecia 100-150/i,, slightly rough with rounded projections. Asci 

 soon evanescent ; ascospores 4-septate, pale brown, slightly contricted, 

 obtuse, 44 x 18/i.

Las Marias, July 10, '15, 8164 (type). 



The distinctive character of the species is the sparse, diffuse, my- 

 celium, with cylindrical, capitate hyphopodia associated with slightly 

 differentiated mucronate hyphopodia.

 celium forming a loose network of threads, lOfi in diam.
