521] MELIOLA IN PORTO RICO — STEVENS 



53 



76. Meuola guareicola sp. nov. 



Colonies epiphyllous, circular, punctiform, 1-4 mm. in diam., black. 

 Mycelium dense, forming a close mat of threads which readily sepa- 

 rates as a whole from the substratum. 



Capitate hyphopodia alternate or irregular, crowded, head cell 

 globular, ovoid or pyriform, 14 x 10/i, the basal cell 2-3/t long. Mucro- 

 nate hyphopodia alternate or opposite, bottle-shaped, the neck narrow, 

 16-18 X 7fi. Perithecial setae none. Mycelial setae numerous, forming- 

 a dense mat covering the colony to the edge, 200-300/i long, 7/t thick,, 

 dark, pale at tip, upper part strongly coiled or twisted. Tip acute. 



Perithecia small, 100-500;^, distinctly ostiolate. Asci soon evanes- 

 cent ; ascospores 4-septate, brown, slightly constricted, obtuse, 37 x lO/i.

This species is usually associated with M. guareae from which it is 

 readily distinguished by its uncinate hairs. 



77. Meliola tecomae sp. nov. 



Colonies amphigenous, mainly epiphyllous, circular, 2-5 mm. in 

 diam. Mycelium black, forming a close network of threads, l/x in diame- 

 ter, branches mostly opposite. 



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

 35/Li long, head cell ovoid, 17 x 13/t, the basal cell 6-10/u. long. Mucronate 

 hyphopodia opposite, irregularly conic, 16-18 x 6fi, no well differentiated 

 neck. Perithecial setae none. Mycelial setae abundant, broadly curved 

 into a large hook at the end, 170 x lOfx, dark throughout, tip obtuse. 



Perithecia 170^, slightly rough with rounded protuberances. Asci 

 soon evanescent; ascospores 4-septate, brown, very slightly constricted, 

 obtuse, 44 x 17/t.
