Septotinia 63 



Apothecia long-stipitate, occurring singly, or several from 

 each sclerotium, at first infundibuliform with the margin in- 

 curved, then umbilicate-discoid, finally slightly convex with the 

 margin reflexed, 2.5-5 mm. in diameter; hymenium yellowish- 

 olivaceous, the margin at first brown, then pallid; stem 10-13 

 mm. long, flexuous, enlarged above, same color as the hymenium, 

 brown below; asci cylindric, 8-spored, reaching a length of 

 140-190 M and a diameter of 9-10^1 spores 1-seriate, broad- 

 ellipsoid, or subfusiform, hyaline, often with two oil drops, 6-8 X 

 12 17 fi; paraphyses filiform, enlarged above. 



On the stems of cultivated Gladiolus. 



Type locality : Europe. 



Distribution: Known only from the type locality. 



This species is included since it was named in honor of an 

 American mycologist. Dr. F. L. Drayton, although it has not 

 been reported from America. It is not unlikely that it will be 

 found here also.
