228 PROCEEDINGS OF THE ACADEMY OF [1890. 



i mm. diani., clothed with short (15-22 />..) straight, spreading 

 bristles, except the papillifbrm ostiolum, finally nearly bare. (Asci 

 long and slender, 5-spored sec. Kellerman and Swingle.) Sporidia 

 elliptical or subglobose, 3-4 x 4-6 //. Distinguished by its small 

 sporidia. 



Rosellinia langloisii. 



On very rotten stem of Vitis, St. Martinsville, La., March, 1889. 

 Langlois 1779 (p. p.). Perithecia scattered, erumpent, the base sunk 

 in the wood, conic-hemispheric, '1 mm. diam. smooth and shiny black. 

 Ostiolum papilliform. Asci about 100 //. long and 5-6 //. thick 

 with abundant paraphyses. Sporidia acutely elliptical, dark- 

 brown, 2-nucleate, 1-seriate, 6-7 x 4 //. Resembles R. aibolanata 

 but perithecia and sjioridia smaller and the white fai'inose coat want- 

 ing. 



Anthostoma ontariensis. 



On dead limbs of Salix, London, Canada, Feb., 1890. J. Dearness 

 1390. Stroma convex \-h mm. diam. more or less subseriately 

 confluent often for several cm., formed of the unaltered substance of 

 the bark and surrounded by a black circumscribing line which 

 penetrates the wood. Perithecia crowded in the stroma, subglobose 

 2-4 mm. diam. with thick coriaceous walls, contracted above into a 

 narrow neck terminated by the subglobose, deeply quadrisulcate, 

 "erumpent, ostiola. Asci slender 8-spored, 90-110 //, long (p. sp 

 75-80 X 8-10 ,u.) with abundant paraphyses. Sporidia subbiseri- 

 ate, cylindrical moderately curved, brown, 20-26 x 4-4^ p.. Has 

 much the same general appearance as some compact forms of Vaha 

 stellulata, Fr. 



Anthostomella ludoviciana, Ell. & Lang. 



On dead stems of Smilax, St. Martinsville, La., Jan., 1889. 

 Perithecia gregarious, covered by the blackened cuticle which is 

 pierced by the papilliform, minutely perforated ostiolum, 140- 

 170 fJ: diam. Asci 50-55 x 3-32 ,'J- cylindrical, paraphysate. 

 Sporidia oblong-elliptical, brown, mostly 2-nucleate, 4-6 (mostly 

 4-5) X 2-2* p- uniseriate. The perithecia are often in subseriate 

 patches, lying so near as to touch each other but hardly coufluent 

 and are buried in the substance of the bark or even in the denuded 

 wood which is then continuously and uniformly blackened on the 

 surface but not within. Distinguished from other allied species by 

 its small sporidia.
