Perithecia hemispherical, 200-333 fi diam., black, rough, crowded, 

 united below in a crustose stroma, bursting out through longitudinal 

 cracks in the bark and forming densely-compacted series, contin- 

 uous or interrupted, 3-5 cm. long, on swollen portions of the limb 

 or stem. Asci 100-120x10-12 /z, subcylindrical, with abundant 

 paraphyses. Sporidia mostly biseriate, cylindric-fusiform, slightly 

 curved, 3-septate, yellowish, 25-30 x 6-7 jut. Bears a general resem- 

 blance to Dothidea morhosa, Schw., but the perithecia are arranged 

 in series and the sporidia are quite different. 



On dead limbs of Artemisia Californica, Mt. Diabolo, Cala. 

 (Harkness).

Perithecia gregarious, superficial, astomous, black, base adnate to

Perithecia globose, astomous, black, 150-200 p. diam., base adnate, 

 finally more or less wrinkled and umbilicate-collapsed above, often 

 covering the whole upper surface of the leaf. Asci clavate, short-stip- 

 itate, 75 x 20 /jl, paraphysate, 8-spored. Sporidia biseriate, oblong- 

 elliptical or subbiconical, uniseptate and slightly constricted in the 

 middle, hyaline, becoming brown, upper cell mostly a little broader, 

 nearly straight, ends obtuse, 20-24x7-8 fi (28-30 x 10-11 p t Sacc.)
