taining 2-8 perithocia having thick, coriaceous walls, and about J mm. 

 diam. The asci are surrounded by abundant paraphyses, and have the 

 spore-bearing part 55-60 x 8 /< long. 8poridia uniseriate, short cymbi- 

 form, opake, 12-14x8 //,as noted by Oke. in Grev. XI, p. 123. The 

 interior of the stroma shows a slight yellowish tint, like that of ^. 

 Sassafras, Schw., but not as distinct. The substance of the stroma is 

 quite soft, almost carnose.

Stromata erumpent-superficial, solitary or subconnate, depressed- 

 pulvinate or hemispherical, generally 1-3 nmi. diam., dark purplish- 

 red, finally black, somewhat uneven from the slightly projecting, small, 

 closely packed, irregularly monostichous, subglobose perithecia with 

 minute, mammilliform ostiola. Oonidia ver.y minute, borne singly at 

 the extremities of short, sparingly branched sterigmata. Asci cylin- 

 drical, on long pedicels, spore-bearing part 80-90 x 7-8 //. Paraph} ses 

 filiform. Sporidia uniseriate, subinequilaterally elliptical, opake and, 

 in the specimens examined, ll-14x 5-6 ii, (12-16 x 5-7 ii, Sacc). 



On dead alder, birch, hazel, beech and other deciduous trees, 

 common throughout the United States and Canada.

Spharia botryosa, Fckl. in F. Rh. 959. 



Stromata erumpent, aggregated and subconnate or oftener tuber- 

 culiform, 1-2 mm. diam., consisting of simple aggregations of perithecia 

 with very little stromatic material interposed, golden-yellow at first, 

 finally black, about I mm. diam., about \ of the upper part of the 

 perithecia projecting. Asci cylindrical, 8-spored, with filiform pai-- 

 aphyses. Sporidia uniseriate, narrow-elliptical, brown, mostly 2- 

 nucleate, 12-14x5-7 n- The inner substance of the bark under the 

 stroma is whitened. 



On bark of a dead willow tree, Pointe a, la Hache, La. (Langlois), 

 We have no authentic specimens of this species, but the Louisiana 

 specimens agree so well with the description of H. botrys, Nits., that 

 we have little hesitation in referring them to it.
