In colony and general characters it resembles M. mayapaeicola, but 

 differs in setae and in shape of capitate hyphopodia. 



24. Meliola toruloidea sp. nov. 



Colonies amphigeuous, more abundant below, circular, 1-4 mm. in 

 diam. Mycelium black, forming rather close network of threads; 

 branches opposite or alternate, T/x in diameter, slightly wavy. 



Capitate hyphopodia alternate, not crowded, one per cell, cells 

 about 20/A long, head cell pyriform, 20 x 14jU,, the basal cell very short, 

 5-6/^. Mucronate hypophodia opposite, bottle-shaped. Mycelial setae 

 none. Perithecial setae few to many, often 30-40 per perithecium, 

 distributed over its surface, strongly uncinate or spirally coiled, about 

 70ft long, 7-8/t thick, black. Young perithecia not radiate, 170ft, slightly 

 rough, with rounded protuberances. Asci soon evanescent; ascospores 

 4-septate, light brown, constricted, obtuse, 34 x 16ft.

 opposite, 8ft in diameter. 



Capitate hyphopodia alternate, not crowded, 17-20fi apart, head 

 cell pyriform, angular and often bent, 20 x 14ft, the basal cell 3-5ft.
