brown, 180-210 x 5-6 p. Asci oblong, about 48 x 12 p, 8-spored, sub- 

 sessile. Sporidia biseriate, obovate, uniseptate, hyaline, 1 2-1 3 x4-4| <i. 

 On living leaves of Quercus laurifolia, Florida (Martin). 



V. erysipheoides, E. & E. Journ. Mycol. Ill, p. 128. 



Perithecia gregarious, black, globose, about 100 p. diam., broadly 

 perforated above, beset with scattering, rigid, black, continuous bris- 

 tles 40-70 x 5-6 p. Asci oblong, sessile, without paraphyses, 40-45 x 

 7-8 /JL. Sporidia crowded, fusiform, hyaline, slightly curved. 5-6- 

 nucleate, about 20 x 2| p. This differs from V. graminicola. Winter, 

 in its smaller perithecia (80-110 //) with shorter, lateral bristles, and 

 in its narrower sporidia (2-2 J p.). The number of bristles on a peri- 

 thecium is generally not over ten or twelve and they stand out hori- 

 zontally or nearly so, reminding one of some of the ErysipJiecz. 



On dead culms or sheaths of Panicum Curtis/' i, Louisiana (Lang-

 Exsicc. Rehm Asc. 293, Ell. N. A. F. 792 (var. foliicola). 



Perithecia subcespitose, globose, collapsing, rather thickly clothed 

 with short (25-35 x 4 //), straight spines. Asci cylindrical, (50 x (> it. 

 with scanty paraphysrs. Sporidia uniseriate, hyaline, uniseptate. 8-10

On bark of pine trees. England and Germany. 



Vox. foliicola (X. A. F. 1. c.) on dead leaA*es ofPinux i'i<jhl<>. 

 still attached to the branches, in a fallen tree top, at Newfield. X. J.. 

 (lifters from the type in its foliicolous growth, scattered perithecia and 

 narrower sporidia (8-10x3-4 ,. 



The typical form, on bark, has not yet (as far as we know) been 

 found in this country.

V. cinchmata, (Fr.) 



Sphezria cincinnata, Fr. S. M. II, p. 451. 

 Vetituria cincinnata, Fr. Summa Veg. Sc. p. 405. 



Peritheeia amphigenons, superficial, solitary, black, very small, 

 conic-cylindrical, smooth, ostiolum hardly visible, crowned with a tuft 

 of erect black hairs about as long as the diameter of the perithecium. 

 Sometimes the perithecium is also surrounded by hairs at the base. 

 On the upper surface of the leaves, the perithecia are less perfect and 

 nearly globose.
