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

 as long as the asci, and 3-3| p. thick. 



( )n dead herbaceous stems, Texas (Ravenel). 



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

Perithecia seattered or subgregarious, covered, black,- subprom- 

 inent. about I mm. cliam. Asci clavate, 90-100x12-15 //, paraphy- 

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

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

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

 an-mis -reins. I "tali ( S. .1. Harkness). 



In the Xe\v 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 < Irevillea. 



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



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

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

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

 eylindrical, sessile, 100-110 x 10-13 ^, 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, 25^0 x 4-5 ,, ends subobtuse. Distin- 

 guished 1 v its sporidia from all other red-tinged species.

L. cousiniilis, 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 eruuipent. Asci subcylindrical, 80-100 x 15 

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

 eylindric-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 Sphceria Baggei, 

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

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