85. Meliola cucuebitacearum sp. nov. 



Colonies epiphyllous, circular, 1-3 mm. in diam. On leaves and 

 stems. Mycelium black, forming a rather close network, 7/* in diameter, 

 branches mostly alternate. 



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

 17 to 24/x, long, head cell ovoid, lobed, 17 x 14/i, the basal cell 7/i, long. 

 Mucronate hyphopodia alternate or opposite, bottle-shaped, 20 x 5/a, 

 neck narrow and crooked. Perithecial setae none. Mycelial setae abun- 

 dant in the older parts of the colony, 190 x 9/*, dark throughout. Tip 

 once or twice dichotomous, branches standing at nearly right angles to 

 the main axis, primary branches 15-35/*, secondary about the same, 

 apices acute. Perithecia 120/*, rough with rounded protuberances. Asci 

 soon evanescent; ascospores 4-septate, broAvn, slightly constricted, obtuse, 

 41 X 14/*. On leaves and stems of an unknown Cucurb, probably 

 Cayaponia.
