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

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

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



Cooke makes the sporidia 18-20x5 /jl. They vary considerably, 

 but 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, <fcc), Newfield, 

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

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

 Lophio stoma.

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

 light orange-yellow, about 165 /jl diam. and a little more than that 

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

 first partially envelops and clothes the perithecia but finally disappears. 

 Ostiola broad papilliform, not distinctly prominent, at length slightly 

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

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

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



Cespitose on the ostiola of some Massaria, on Fraxinus i} . and 

 Ulmus, Canada (Dearness).

Erumpent, cespitose, suborbicular. Perithecia rather small, smooth, 

 scarlet, papillate, at length collapsed, crowded on a pale stroma. Asci 

 cvlindric-clavate, 8-spored. Sporidia-fusiforni, hyaline, 5-septate, 30 x

Very minute, scarlet. Asci lanceolate but obtuse. Sporidia 

 sometimes larger, binucleate, at length triseptate (uniseptate, Berk.), 

 uniseriate, or smaller, 4-nucleate, biseriate, 25-30 x 8| jjl.
