threads, globose, evanescent. Sporidia hemispherical, echinulate. 



This genus (sec. Sacc. Syll. IX. p. 943) is probably not distinct 

 from Inzengc&a, Borzi. 



Cl. purpiireuin, Hark. 1. c. 



Perithecia purple-black, very delicate, soon dehiscent, developed

 stains purple. Asci globular, hyaline, 8-spored. 9-12 p diam. Spo- 

 ridia hemispherical, purple, long-echinulate around the margin. 3-4 //.

Minute, scattered or emerging in dense groups from tho epider- 

 mis or cracks in the bark, or on the truncate i-nds of limbs. Peri- 

 thecia without any manifest stroma, sphaeroid, obtuse, astomous, or 

 marked at the apex with a minute, impressed point, dark brown, 

 rugulose and subpulverulent, rather thick-walled, carbonaceous, fragile, 

 npake. Asci terete, elongated, 8-spored. Sporidia oblong, 4-celled,

Lophiostoma pallidum, EH. Bull. Torr. Bot. Club, X, p. 52. 



Perithecia scattered or gregarious, often two or three standing 

 close together, but not confluent, erumpent-superficial, subglobose. 

 black, rough, about \ mm. diam., collapsing above. Ostiolum papilli- 

 forin, minute. Asci subcylindrical, sessile, 75-80x12-15 JJL, with 

 rather scanty, filiform paraphyses. S]oridia biseriate, clavate-oblong, 

 yellowish-hyaline, about 7-septate, slightly curved, obtuse, 18-22 x 

 5-7 fjL. 



On weather-beaten wood of " Service bush,'' Utah (S. J. Harkness ;. 



On account of the minute, papilliform ostiolum. this can hardly 

 be a Lophiostoma.
