tlu'eads, globose, evanescent. Sporidia hemispherical, echinulate. 



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

 from InzengcBa, Borzi. 



CI. purpiireuni, Hark. 1. c. 



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

 within the heaps of Thecospora bifida (its conidial stage), which it 

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

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



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 // 

 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 n, 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.
