 U. (Tetrastaga) rostellata (Fr.) Nits.

On Pinus rigida at Glade Creek, and on Pinus Virginiana, 

 May 4, 1894. Spores very variable ■+ 35 x 12 /^ {Nuttall,

VALSARIA Ces. & DeNot. 

 V. exasperans (Ger.) Sacc. 



On Juglans cinerca, Nov. 3, 1893 {Nuttall, 1260, 202).

Type habitat : On bark of dead limbs Magnolia acu- 

 minata, April 25, 1895 {Nuttall, discov. 1818, 700, 705). 



Perithecia scattered, buried in the bark, depressed-globose. 

 .75 to 1.25 mm. diameter, the subconical ostiolum piercing 

 but not perceptibly raising the bark. Asci broad oblong, p. 

 sp. 150 to 200 X 55 to 65 ft. with a very short, nodular stipe, 

 8-spored, paraphysate. Sporidia crowded-biseriate, oblong 

 or clavate-oblong, 3 to 5-septate, mostly 3-septate, when 

 young, hyaline at first, finally deep brown and then with 

 only one distinct septum, though often i to 4 other faint 

 septa can be seen. There is a distinct constriction at the 

 main septum, which is a little below the middle of the spore, 

 but none at the other faint septa which are often wanting. 

 The sporidia measure 65 to 80 x 20 to 25 /*, larger than in 

 M. foedans (Tode), which has sporidia about 50 x 20 /*, 3- 

 septate and constricted at all the septa, besides being more 

 distinctly narrowed below.
