150 PROCEEDINGS OF THE ACADEMY OF [1893. 



Barrow, obtuse margin. Asci clavate-cylindrical, 80-100x12//, 

 with filiform paraphyses curved at the tips. Sporidia cylindrical, 

 hyaline, multiseptate nearly straight, 40-60 x 2ifi. The perithecia 

 are at first nearly globose but as the hymenium develops they 

 become excavated above and finally concave. 



Blitrydium sabalidis E. & E. 



On partly living leaves of Sabal palmetto, Bayou Chene, La. 

 Oct., 1888. (Langlois, No. 1,772.) 



Perithecia scattered or gregarious, black, conical and closed at 

 first, then open exposing the smoky-gray disk which becomes dirty 

 white, margin sublacerate toothed and subincurved, about \ mm. 

 diam. All the upper part finally falls away leaving only a black 

 circle with a white center. Asci cl a vate, 40-50 x 15-20//. Para- 

 physes none? Sporidia crowded brownish-yellow, oblong, 4-septate 

 with the next to the upper cell divided by a longitudinal septum, 

 15-20 x 6-7/;. 



This is very distinct from Dermatea sabalidis E. & M. (Cenangium 

 sabalidis in Sacc. Syll. vol. VIII, p. 562.) 

 Diplonsevia melaleuca E. & E. 



On decorticated Poplar, Sand Coulee, Montana. Oct., 1889. 

 (F. W. Anderson, No. 645.) 



Perithecia at first closed and buried in the wood, about 1 mm. 

 diam. carnose-membranaceous, thin and black, soon partly erumpent 

 with a round opening at the apex, the margin narrowly white lacer- 

 ate-fimbriate. Disk livid, concave. Asci subcylindrical,subsessile, 

 75-85 x 6-8//, surrounded by abundant filiform paraphyses slightly 

 longer than the asci, their tips bent or curved but not distinctly 

 thickened. Sporidia 6-8 in an ascus, biseriate, cylindrical, hyaline, 

 curved, obtuse, 1-septate, 12-15 x 3//. 

 Stictis schizoxyloides E. & E. 



On dead limbs among driftwood, Mill Creek, Montana. Jan., 

 1892. (Mrs. L. A. Fitch.) 



Ascomata scattered or gregarious, about half sunk in the wood, 

 the upper part convex-hemispherical and prominent, 1-1 2 mm. diam., 

 pierced in the center with a small round opening, outside cinereo- 

 furfuraceous and rough. The apical opening gradually enlarges 

 till the glauco-cinereous, concave disk is entirely exposed, bordered 

 by the slightly incurved, prominent margin, appearing then like 

 little cups sunk in the wood. Asci oblong-clavate, sessile, 8-spored,
