bosa, 8ch\v. from which, however, this is quite distinct. The stroma 

 is carnose and black inside and out, and in the bark beneath it are 

 buried the numerous small abortive perithecia of a Diatrype or Valsa. 

 Teichospora mammoides. 



On dead stems of Sarcobatus vermiculatus near Great Falls, 

 Montana, July, 1889. F. W. Anderson, 542. Perithecia erumpent- 

 superficial, gregarious, depressed-hemispherical, brownish-black, f 

 mm. diam. with a prominent nipple-like black ostiolum. Asci 

 clavate-cylindrical, subsessile, 100-110 x 12-15 [j.. with abundant 

 filiform paraphyses. Sporidia uniseriate, ovate-oblong 5-7 septate 

 and muriform, scarcely constricted, yellow becoming brown, 20-22 

 x9-ll //.. 

 Teichospora mycogena. 



Parasitic on old Diatrype stigma, Newfield, K. J., Apr., 1889. 

 Scattered immersed except the partially erumpent apex which 

 slightly raises the surface of the Diatrype stroma rupturing it in a 

 subradiate manner. Perithecia of medium size with an indistinct 

 ostiolum. Asci subcylindrical about 100 x 12 //. abruptly con- 

 tracted below into a short stipe. Sporidia biseriate, ovate-oblong, 

 with three distinct transverse septa and a longitudinal septum across 

 (me or more of the cells, yellowish becoming dark brown, distinctly 

 constricted at the middle septum and when mature 5-6-septate, 12 

 —15 X 6-8 //.. This might be mistaken for Lophiostovia fioridanum 

 E. & E. but that has the perithecia more superficial and quite differ- 

 ent sporidia. 

 Teichospora umbonata. 



On dead branches of Symphoricarpiis occidentalis, Helena, Mon- 

 tana, March, 1889. Rev. F. D. Kelsey, No. 7. (in part). Perithecia 

 gregarious, discoid, about i mm. diam. seated on the surface of the inner 

 bark exposed by the fiilling away of the epidermis, ostiolum tuber- 

 culiform. Asci cylindrical 75-80 x 7-8 //. with paraphyses. Sporidia 

 uniseriate, ovate, 3-septate, constricted at the middle septum, straw- 

 yellow, 12-15 X 6-8 //.. Most of the sporidia show only the three 

 transverse septa but in some of them one or both the inner cells 

 are divided by a longitudinal septum. It is not improbable that 

 the sporidia may finally become brown and acquire additional 

 septa. 

 Teichospora papillosa.
