taining 2-6 perithccia having thick, coriaceous walls, and about J mm. 

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

 spore-bearing part 55-60x8 // long. Sporidia uniseriate, short cymbi- 

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

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

 Sassafras, Schw., but not as distinct. The substance of the stronui i- 

 quite soft, almost carnose.

Stroma ta erumpent-superficial, solitary or subconnate, depr< 

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

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

 closely packed, irregularly monostichous, subglobose perithecia with 

 minute, mammilliform ostiola. Conidia very minute, borne singly nt 

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

 drical, on long pedicels, spore-bearing part 80-90 x 7-8 ft. Parapl 

 filiform. Sporidia uniseriate, subincquilaterally el liptical, opake and. 

 in the specimens examined, 11-14x5-6 //, (12-16x5-7 fjt, Sacc).

Sphteria bolryosa, Fckl. in F. Rh. 959. 



Stromata erumpent, aggregated and subconnate or oi'tener tuber 

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

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

 finally biack, about \ mm. diam., about \ of the upper part of the 

 perithecia projecting. Asci cylindrical, 8-Spored, with fililbrm par- 

 aphyses. Sporidia uniseriate, narrow-elliptical, brown, n 

 nucleate, 12-14x5-7 /*. 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 specie, but the Louisiana 

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

 we have little hesitation in referring them to it.
