(Figures 37, 38) 

 Mycelium apparently saprophytic in the cortical tissue of oak; 

 stromata small, approximately 0.3 mm. in diameter, scattered, 

 usually hidden in the crevices of the bark, bearing a cespitose 

 cluster of pycnidia and perithecia, the perithecia protruding at 

 maturity from the crevices in the bark as minute, slender, black 

 spines; perithecium glabrous, dull to shiny, reaching 1.5 mm. in 

 length, when young probably coriaceous and white within, in age 

 or in dried specimens becoming brittle and easily broken away, 

 consisting of a long stalk, a median or sub-apical enlargement 

 containing the ascigerous cavity, 3 and a terminal beak ; the en- 

 largement sub-cylindrieal-vesiculose, 200-325 /x long and reaching 

 150/x in lateral diameter at the middle, sometimes laterally col- 

 lapsed as in C. pinea but not inclined to one side as frequently 

 happens in that species ; the stalk long, slender, 80-125 fi in diam., 

 cylindrical, straight to flexuous, swollen at the point of attach- 

 ment to the stroma ; beak of approximately the same diameter as 

 the stalk, occasionally attenuated toward, the tip especially when 

 young, in some perithecia exceeding 500/x in length, traversed by 

 a narrow canal ; the apex in immature stages sharp-pointed, 

 closed, at maturity becoming minutely fimbriate-lacerate, and 

 having a reddish-brown, fuzzy appearance, finally dehiscent, the 

 terminal hairs spreading apart and forming a fringe around a 

 definite opening; asci ovate to clavate, 12-15X7-97* (p. sp.). 

 spores ellipsoidal to oval or globose, 3-4 X 4-5 fi ; pycnidia ap- 

 proximately 100^, broad; pycnospores 2.5-3.5^ long. 



3 In the specimen of E. & E. N. A. F. 2nd series No. 2123 in Professor 

 Thaxter's herbarium at Harvard University one abnormal and unusually long 

 perithecial stalk was observed which had developed a half-dozen lateral buds, 

 apparently containing ascigerous cavities.
