threads, globose, evanescent. Sporidia hemispherical, echinulate. 



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

 from Inzengma, Borzi. 



CI. purpiireum, Hark. 1. c. 



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

 within the heaps of Thecosp'ora bifida (its conidial stage), which it 

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

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



On rotting leaves of Eucalyptus, San Francisco, Cal. (Harkness).

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

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

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

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

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

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

 somewhat constricted at the septa, pale fuliginous, diaphanous, 15 ft 

 long or a little less. On bark of Betula, Bethlehem, Pa. (Schw.).

Lophiostoma pallidum, Ell. 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- 

 form, minute. Asci subcylindrical, sessile, 75-80x12-15 fi, with 

 rather scanty, filiform paraphyses. Sporidia biseriate, clavate-oblong. 

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

 5-7 ii. 



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



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

 be a Lophiostoma.
