brown, multiseptate, at length slightly constricted at the septa, nearly 

 as long as the asci, and 3-3| /j. thick. 



On dead herbaceous steins, Texas (Ravenel). 



The foregoing diagnosis is from specc. in our Herb, from Ravenel.

Sphceria clavigera, C. & E. Grev. VI, p. 16. 

 Leptosphczria clavigera, Sacc. Syll. 3008. 

 Heptameria, clavigera, Cke. Syn. 4812. 



Perithecia scattered or subgregarious, covered, black, subprom- 

 inent, about J mm. diam. Asci clavate, 90-100x12-15 /jl, paraphy- 

 sate and stipitate. Sporidia crowded, clavate-fusoid, slightly curved, 

 reddish-brown, 7-9-septate, one joint (near the middle) sometimes 

 swollen, 25-35 x 6-8 p (40 x 8 /*, Cooke). 



On dead stems of Phytolacca, Newfield, N. J., and on dead herb- 

 aceous stems, Utah (S. J. Harkness). 



In the New Jersey specc. of this species, the sporidia remain for 

 a long time hyaline and uniseptate, only a few being seen with 4-5 

 septa and pale reddish-brown, but the Utah specc. agree well with the 

 diagnosis in Grevillea. 



L. rubrotincta, E. & E. Journ. Mycol. I, p. 150. 



Perithecia scattered, membranaceous, depressed-globose, 200-250 

 fi diam., perforated above, covered by the slightly elevated epidermis, 

 which is slightly ruptured, and stained pale blood-red. Asci clavate- 

 cylindrical, sessile, 100-110 x 10-13 /i, sessile and accompanied by 

 paraphyses. Sporidia biseriate, cylindrical, straight or slightly 

 curved, deep straw-yellow, 8-10-septate with one joint (a little below 

 the middle) slightly swollen, 25-40 x4-5 /i, ends subobtuse. Distin- 

 guished by its sporidia from all other red-tinged species. 



On dead twigs of Staphylea trifolia, West Chester, Pa. (Ever- 

 hart.) 



L. cousimilis, E. & E. Journ. Mycol. II, p. 41. 



Perithecia scattered, carbonaceo-coriaceous, | mm. diam., at first 

 covered and raising the fibers of the wood or bark into little pustules. 

 Ostiola papilliform, soon erumpent. Asci subcylindrical, 80-1 00 x 15 

 -20 .//, with abundant paraphyses. Sporidia 8 in an ascus, subbiseriate, 

 cylindric-fusiform, 3-septate and subhyaline at first, becoming yellow, 

 and finally dark brown, and about 7-septate, more or less constricted 

 at the septa, 28-35 x 8-10 p.. Apparently allied to Sphwria Baggei, 

 Auersw., which is said to have greenish-yellow, 3-5-septate sporidia. 

 In the Dakota specimens, the mature sporidia are quite constantly 7-
