regular, usually bent to one side, 10 x 17/j.. Ampulliform liypliopodia 

 alternate, 7 x 21/x. 



Perithecia numerous, clustered, black, 150-170/i., slightly flattened, 

 cup-shaped when dry, rough with low tubercles. Asci 4-spored, 65 x 21 ix.

This species resembles M. montagnei, differing from it in color, 

 spores, thickness, and density of mycelium. 



58. Meliola serjaniae sp. nov. 



Colonies hypophyllous, irregular, black, 1-6 mm. in diam. Mycelium 

 forming a loose network of threads which branch irregularly, 6/j, in 

 diameter. 



Capitate hyphopodia small, alternate or irregular, distant, 40-70/u, 

 apart, head cell ovoid or pyriform and much lobed, 17 x 10^, the basal 

 cell 3-6/i-. Mucronate hyphopodia usually more abundant than the capi- 

 tate hyphopodia, opposite, bottle-shaped to conic, narrow, 24 x 6/x. Peri- 

 thecial setae none. Mycelial setae abundant, black throughout, straight 

 or slightl.y curved, 280-800 x 10^. Tip abruptly acute. 



Perithecia 150-190/i,, smooth. Asci soon evanescent ; ascospores 4- 

 septate, brown, constricted, obtuse, 41 x 17/x,

Vega Baja, Feb. 22, '13, 425 (type). Florida Adentro, July 1, '15,

This form is clearly differentiated from M. pareiichijmate, M. am- 

 higua, and M. tJiouiniae previously described on the Sapindaceae, all of 

 which have simple mycelial setae. The chief characters are angular, 

 capitate hyphopodia, long, abruptly pointed setae, and numerous mucro- 

 nate hyphopodia. 



59. Meliola dipholidis sp. nov. 



Colonies amphigenous, irregular, circular, 2-5 mm. in diam. My- 

 celium black, forming a loose network, 7/a in diameter, branches mainly 

 opposite. 



Capitate hyphopodia small, alternate or irregular, not crowded, 1 

 per cell, cells about 27/a long, head cell obovoid to pyriform or globular, 

 often angular or bent, 17 x IO/jl, the basal cell b-l/x long. Mucronate
