subhemispherical tubercle, 1-2 mm. across, and less than 1 nun. high, 

 minutely papillose above from the slightly projecting ostiola. The 

 upper, projecting part of the stroma, is of a light horn-color inside. 

 Perithecia 10-20 irregularly crowded in the bottom of the stroma, 

 ovate-globose, with thick, coriaceous walls, contracted above into slen- 

 der necks 1 mm. or more long, terminating above in the papilliform 

 ostiola. Asci slender, 75-80x5-6 it (p. sp.). Paraphyses abundant, 

 longer than the asci. Sporidia obliquely uniseriate, oblong, crowded, 

 cylindrical, 2-nucleate, brown, uniseptate, 10-12 x 3| fx. Allied to 

 V. anthostomoides, Sacc. 



On dead limbs of Salix, London, Canada (Dearness).

Covered. Pustules scattered, scarcely prominent, composed of 

 6-10 perithecia, at length perforating the cuticle. Ostiola short and 

 obtuse. Asci ample. Sporidia elliptical, constricted in the middle, 

 ends rounded, uniseptate, brown, 50 x 25 p.. 



On branches of Salix, California (Harkness). 



Sometimes the large sporidia are extruded and form blackened 

 spots around the ostiola as in Massaria, but this is not a constant 

 feature. The absence of any hyaline investment of the sporidia also 

 confirms this as a Valsaria rather than a Massaria.

Perithecia irregularly circinate, subimmersed. Ostiola black, 

 emergent in a brown, pruinose disk. Asci cylindrical, attenuated 

 below, 8-spored. Sporidia uniseriate, elliptical, uniseptate, brown, 

 constricted, 20 x 10 fx.

Forming subangular pustules about 2 mm. broad, rather effused 

 at base, as seen through the thin cuticle. Disk angular, tawny, pul- 

 verulent, pierced by the black, angular, punctiform ostiola. Stroma 

 tawny like the disk. Perithecia globose. Asci linear. Sporidia 

 elliptical, uniseptate, with a single globose nucleus in each cell, ends 

 subacute, becoming dark brown, 15-18 fi long. 



On branches of Platanus, Ohio (Lea). Carolina (Curtis), Con- 

 necticut (Wright).
