form, minute, but distinct. Asci cylindrical, 65-70x6//, narrowed 

 below into a stipe 25-30 <>. long, p. sp. 55-60 //. long, indistinctly 

 paraphysate, 6-8-spored. Sporidia uniseriate, lying end to end in 

 the asci, oblong-elliptical, uniseptate, but not constricted, pale brown, 

 7-10x3i-4/<. 



Differs from A. Oronoensis in its larger, pilose, sub-collapsed peri- 

 thecia and rather larger sporidia. 



Teichospora nitida E. & E. 



On dead stems of Rubus deliciosus, Rist Canon, Colo., April, 

 1894. Prof. C. S. Crandall, No. 108, and on Rubus villosus, Nut- 

 tallburg, West Va., May, 1895. L. W. Nuttall, No. 706. 



Perithecia thickly scattered, ovate-globose, 350-400 //. diam., at 

 first covered by the epidermis which is raised and pierced by the 

 black, papilliform ostiola, at length, when the epidermis falls away, 

 superficial. Asci clavate-cylindrical, paraphysate, 8-spored, 90- 

 110x11-13//.. Sporidia uniseriate or subbiseriate above, oblong- 

 elliptical, obtusely pointed, 3-5-septate, with a longitudinal septum 

 running through part or all the cells, 15-20 x 8-10, a, pale, yellow- 

 ish-brown, slightly or not at all constricted in the middle. 



The West Va. specc. have the perithecia rather smaller 250— 

 300 // diam. 



Teichospora minima E. & E. 



On a dry oak post, mixed with Rosellinia pulveracea Ehr. , var. 

 microspora, Rockport, Kansas, Oct., 1894. E. Bartholomew 1,591. 



Perithecia scattered, small 100-110 //, collapsing, nearly smooth, 

 with a papilliform ostiolum. Asci clavate-oblong, short-stipitate, 50 

 x 12-15//. p. sp. 40-46//. long, paraphysate, 8-spored. Sporidia 

 crowded-biseriate, elliptical, about 5-septate, not constricted, 12-15 

 x 7-8 //., olive brown. 



Differs from T. pygmaea E. & E. in its smaller, collapsed perithecia 

 and shorter asci. 



Lophiostoma clavisporum E. & E. 



On dead culms of Elymus Canadensis. Rooks Co., Kansas 

 March 18, 1895. Bartholomew, No. 1,694. 



Perithecia scattered or gregarious, buried, except the erumpent, 



thin, flattened ostiolum, 300x150//, culms mostly blackened on 



the surface. Asci clavate-cylindrical. short-stipitate, paraphysate, 



40-60x12//.. Sporidia crowded in the asci, clavate, 3-5-septate,
