100-125x12-15 fi, with abundant, filiform parapbyses. Sporidia 

 biseriate, broad-fusiform, slightly curved, subhyaline. 1-3-septate arid 

 constricted at the middle septum, 25-35x7-8 /i. 



Cooke makes the sporidia 18-20x5 ji. They vary considei-ably, 

 Imt mature and well developed specimens have the sporidia as above. 



On bark of Ulmus, seaboard of South Carolina (Ravenel), on 

 various kinds of decaying wood and limbs, (oak, Rhus, &c.), Newfield; 

 X. J., and on decaying elm, Canada (Macoun & Dearness). The 

 ostiolum is sometimes more or less compressed, so as to resemble 

 Lophio stoma.

Pcrithecia 3-12 in a cluster, ovate, narrowed above and below,

 in height, seated on a white, radiate-fibrous, silky mycelium which at 

 first partially envelops and clothes the perithecia but finally disappeai-s. 

 ( )stiola broad papilliform, not distinctly jjiominent, at length slightly 

 collapsing. Asci 75-80 x 10-1 2 /u, with paraphyses. Sporidia oblong- 

 cylindrical, obtuse, yellowish-hyaline, biseriate, 3-5-septate, more, or 

 loss constricted at the septa, 25-35 x 6-7 /i, ends obtuse, slightly curved. 



Cespitose on the ostiola of some Massar/a, on Fraxinusi and 

 Ulmus, Canada (Dearness).
