Globulina antennariae sp. nov. 



Perithecia superficial, scattered, ovate or pyriform, brown mem- 

 braneous, having a distinct ostiolum : asci cylindrical, slightly 

 narrowed at the ends, mostly somewhat curved, 90-120x4-5 ft ; 

 paraphyses flaccid, usually longer than the asci : spores very- 

 slender and filiform, septate, hyaline, 90-105 fi long, easily break- 

 ing into shorter segments.
