Ellis and Everhart : New Species of Fungi 53 



ostiolum conic-papilliform, distinct : asci cylindrical or clavate- 

 cylindrical, stipitate, paraphysate, 80-1 10 x 8— io/e: sporidia uni- 

 seriate, oblong-elliptical, yellow-brown, 3-septate, becoming lightly 

 constricted, especially at the middle septum, 14-16 x 7-8 /<. 



The sporidia are much like those of L. fuscella B. & Br., but 



in that species the perithecia are buried and have no ostiolum. 



Thyridium vitis E. & E. 



On dead shoots of Vitis riparia, Rooks Co., Kansas (Bar- 

 tholomew), 



Perithecia gregarious, often 2-3 subconfluent, entirely buried 

 in the bark which is raised into low, flattish pustules over them, 250- 

 300 fi in diameter, grayish inside, thin-walled, globose : ostiolum 

 inconspicuous, barely penetrating the bark : asci clavate-cylindrical, 

 short -stipitate, 100-115 x 15-18/*, with abundant paraphyses : 

 sporidia obliquely uniseriate, or subbiseriate above, obovate-oblong, 

 brown, 5-7 -septate, constricted in the middle, obtusely rounded at 

 the ends, 18-22x10-12//, with a longitudinal septum running 

 through one or more cells. 



Differs from T. antiquum E. & E. in its larger asci and larger, 



differently shaped 5-7-septate sporidia. 



Hysterographium graminis E. & E. 



ipogon provincia 



March 



Erumpent-superficial, 0.5-1 mm. long, 150-200// broad, 

 rounded at the ends, with a slight longitudinal furrow along the 

 center: asci clavate-oblong, short-stipitate, paraphysate, p. sp. 

 6o ~75X 15-20/^: sporidia biseriate, oblong-elliptical, yellow, be- 

 coming brown, 3-septate, compressed, scarcely or only slightly 

 constricted at the septa, 16-20 x 7-10 p, 5-6// thick, with a longi-

viewed edgewise only the transverse septa are visible. 



The sporidia resemble very much those of some species of 

 Pleospora, as P. aurea, P. compressa, P. permunda, etc. 



Hypoderma equiseti E. & E. 



On dead stems of Equisctum hyemale, Rooks Co., Kansas, 

 Jan., 1899 (Bartholomew, no. 2535). 



Perithecia oblong or linear, 1-3 mm. long, covered by the thin 

 epidermis which is split along the middle: asci oblong-clavate,
