oblong 4-4V X 1 •] //. sporules without any evident basidia. The 

 upper half finely radiate-striate, texture close, fine radiate-cellular. 

 The perithecia are enveloped in a loose, glauco-cinereous mycelium 

 of the same color and character as that in M. EverhartU from which 

 this differs in its smaller sporules and smaller striate perithecia with 

 an apical opening. 



Calosphaeria alnicola. 



On dead alder, Newfield, N. J., March, 1889. Subcuticular, 

 Perithecia scattered, subglobose, ^ mm. diam., roughish,. seated on 

 the surface of the inner bark, at length slightly collapsed above. 

 Ostiola short-cylindrical, slightly raising and barely perforating the 

 epidermis. Asci racemose-fasciculate, clavate-oblong, 20-22 x 82- 

 4 ,".., 8-spored, the upper end of the spore-mass truncate and sur- 

 mounted by the empty transparent, dome-shaped apex of the asci. 

 Spores crowded-biseriate, allantoid, curved, 0-6 x 1 ,'j.. 



When the epidermis is peeled off the perithecia either adhere to it 

 or remain attached to the inner surface of the bark, in which respect 

 this differs from Sphaeria secreta, C. & E. in which the perithecia 

 always adhere to the epidermis. This latter species also has longer 

 distinctly clavate asci with a long, slender base and longer sporidia 

 and is we believe specifically distinct from the species on alder 

 though much resembling it. 



Calosphaeria microsperma E. & E. 



On Carpinus Americana, London, Canada, Apr., 1890. Dearness, 

 1587. Perithecia subcuticular, circinate, 6-18 together, about i 

 mm. diam., their cylindrical necks converging and erumpent in a 

 small compact fascicle of short ostiola projecting but slightly and 

 mostly 4-sulcate. Asci clavate 22-25 x 4 //. gradually attenuated 

 to a slender base, paraphyses much longer than the asci. Sporidia 

 minute, SJ x f /j.. curved into a semicircle. 



Coelosphaeria corticata. 



On bark of dead Madura aurantiaca, Emma, Mo., Nov., 1889. 

 Rev. C. H. Demetrio, 272. Perithecia scattered, globose, about h. 

 mm. diam. closely enveloped except the papilliform ostiolum and 

 the apex by the adherent epidermis, and clothed with a thin coat of 

 brown, branching, sparingly septate hairs about 3 //. thick. Asci 

 (p. sp.) about 35 x 7 !)■. 8-spored. Sporidia crowded biseriate, 2- 

 nucleate, hyaline, moderately curved, obtuse, 10-14 x 3 'j.. The
