 Nectria striispora, Ellis & Everh. Bull. Lab. Nat. Hist. St. Univ. 

 Iowa 2 : 398. 1893. 



Perithecia in irregular, dense, cespitose clusters as large as 5 

 mm. in diameter, consisting of 20-100 perithecia each ; individual 

 perithecia subcylindrical, tapering above into an obtuse ostiolum 

 which in mature specimens is quite prominent, at first covered 

 with a yellowish furfuraceous coat, finally amber; asci clavate, 

 tapering above, about 100 X 15 mic, 8-spored; spores crowded in 

 the ascus, large, fusoid, straight or curved, i-septate, with several 

 large oil-drops in each cell, slightly constricted at the septum, pale 

 brown, becoming striated, 35-48 X 10-12 mic. ; paraphyses in- 

 distinct. 



On bark and rotten wood. 



Type locality : Central America. 



Distribution : Known only from type locality. 



Exsiccati : C. L. Smith, Central Am. Fungi, 6. 



The spores in this species resemble in size and color the teleuto- 

 spores in some of the common rusts. The striations are quite 

 prominent but do not appear to roughen the outer surface but to 

 be due to some internal markings or contents. 



18. Gibberella Sacc. Michelia 1 : 43 (in note). 1879 



Stromata (Fusarium) tubercular or more or less effuse; peri- 

 thecia cespitose or occasionally scattered on or surrounding the 

 stromata; asci clavate, 8-spored, spores fusoid; 3-many-septate, 

 hyaline.

Perithecia in cespitose clusters .5-1 mm. in diameter, seated on 

 a stroma or occasionally more or less scattered around it, ovate
