The species is remarkable for the very numerous larvaeform appen- 

 dages, it appearing as though nearly every superficial cell of the peri- 

 thecium develops into an appendage. The appendages are closely 

 marked with transverse striae which simulate septa. The capitate hy- 

 phopodia are also characteristic. It resembles M. inermis, but distin- 

 guished from it by the smaller spores and more angular hyphopodia. 



20. Meliola arecibensis sp. nov. 



Colonies hypophyllous, irregular, 1-3 mm. in diam. Mycelium form- 

 ing a rather close net work of threads which are slightly crooked and 

 branch either opposite or alternate, about 6/x in diameter. Capitate 

 hyphopodia alternate, one per cell, cells about 10-17/x long, head cell 

 ovoid to cuneate or very irregular, 20x10/*, the basal cell varying 

 from short to quite long, 20/i,. Mucronate hyphopodia abundant, us- 

 ually opposite, bottle-shaped, narrow, 20/a long. Mycelial setae none. 

 Perithecial appendages larvaeform, few, 4-8,. short, about 85/*, 20/t thick, 

 curved to crooked, translucent, darker at tip. Perithecia 200/*, rough, 

 with rounded protuberances, ostiole none. Asci soon evanescent ; asco- 

 spores 4-septate, dark brown, very strongly constricted, obtuse, 44-51 x 

 20/*.

This species collected only once is very striking. Possessing no 

 setae either perithecial or mycelial and having the larvaeform chitinous 

 appendages it falls within a class of but few members. It is also remark- 

 able for the great variation in form and size of both kinds of hyphopo- 

 dia, a variation far greater than I have seen on any other species. It is 

 clearly seperated from M. acalyphae by its chitinous appendages and 

 character of the hyphopodia. 



21. Meliola miconieicola sp. nov. 



Colonies hypophyllous, irregular, diffuse, 5-20 mm. in diam. Myce- 

 lium forming a very loose network of slightly wavy threads with 

 branches mostly opposite, 6/* in diameter. 



Capitate hyphopodia small, alternate or irregular, very distant, 

 about 75/t apart, head cell ovoid or pyriform, sometimes slightly 

 irregular, 17 x 14/*, the basal cell 4-10/* long. Mucronate hyphopo- 

 dia few and scattered, mostly opposite, bottle-shaped, narrow, crooked,
