 ing to reddish. Asci cylindric-clavate, obtusely rounded above, briefly 

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

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

 cylindrical, uniseptate, 10-13x3-4 /*, cells equal, 2-nucleate, hyaline.

N. microspora, C. & E. Grev. V.p. 53. 



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

 3-15. Perithecia subgiobose, 150-200 // 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 // (p. sp.). Sporidia 

 elliptical, uniseptate, hyaline, 6-7x3J-4 p.. Groups of perithecia \-\ 

 mm. across. Stroma not conspicuous. 



On bark of dead Magnolia, Newfield, N. J., and on bark of dead 

 beech, Lake Nipigon, Canada. 



In the Newfield specimens the perithecia are only partially col- 

 lapsed above so as to appear truncate.

 lum darker. Asci cylindrical, 50 x 6-7 p. Sporidia biseriate, oblong- 

 fusoid, 8-12x3 ^ 2-nucleate, becoming tardily uniseptate, hyaline." 

 Stroma pale, flattish, scarcely rising above the epidermis.

Cespitose, erumpent, pale red. Perithecia few, oval, soft-waxy- 

 subconfluent, smooth, glabrous, 5-10 on a stroma. Asci cylindrical. 

 8-spored. Sporidia uniseriate, elliptical, obtuse, uniseptate, not con- 

 stricted, hyaline, 10x4| fi. Conidia (Fusarium Acacice, Cke. A 

 Hark.), either accompanying the perithecia on the same stroma or pro- 

 duced in separate pustules of earlier growth, on a pale red. pulvinate
