(7M by 14^), bearing prickly, spheric conidiospores 7 to 30/1 in diameter 

 which are larger than any other well-known species. It produces 

 perithecia also with readiness and in abundance. The at first pale 

 brown-yellow perithecia, later brown, are about 100 to 200/1 in diame- 

 ter in closing numerous asci which contain five to eight colorless 

 smooth eUipsoidal spores, exhibiting a furrow directed longitudinally 

 and 5 to 8/i broad by 7 to loju long. The perithecium develops gradu- 

 ally from spirally coiled h}^hae. The hyphae of the screw are divided

transversely into as many cells as there are turns of the screw. The 

 bottom hyphal cells of the screw send up two or three branches of 

 irregular thickness which grow toward the apex. One of these branches 

 looked upon as an antheridium grows more rapidly than the others and 

 its contents serve to impregnate the inclosed carpogone. These outer 

 erect hj^jhae then branch copiously to completely envelope the carpo- 

 gone and the perithecial wall is thus formed. From the carpogone are 

 now formed the numerous ascogenous hApha", which branch plenti-
