 stipitate below, 40-45. or more rarely 60-70x5-7 //, without paraph- 

 yses, 8-spored. Sporidia distichous or obliquely monostichous, elliptic-

N. microspora, (\ & E. Grey. V.p. 53. 



Cespitose, bursting out through cracks in the bark in groups of 

 3-15. Perithecia subglobose, 150-200 p. diameter, orange-red, seated 

 on a scanty, white, web-like mycelium, collapsing above, with a papil- 

 liform ostiolum. Asci cylindrical, 50-60 x 5-6 ;JL jjp. sp.). Sporidia 

 elliptical, uniseptate, hyaline, 6-7x3^-4 p. Groups of perithecia |-1 

 mm. across. Stroma not conspicuous.

 beech, Lake Xipigon, Canada. 



In the Xewfield specimens the perithecia are only partially col- 

 lapsed above so as to appear truncate.
