Perithecia attached to the border of a small, tough-coriaceous, 

 plano-convex or finally concave, black stroma. superficial, small, brown-

 cylindrical, 8-spored. Sporidia oblong-, hyaline, becoming imiseptate.

Stromata flat, convex, becoming concave, small (250-300 p. diam.), 

 black, shining, usually collected in compact, circular groups scattered 

 irregularly over the surface of the leaf, or ranged in a circle, with a 

 vacant space in the center. The margin of each stroma is fringed 

 with copious, bristle-like, straight, septate, olive-brown hairs 60-1 30 x 

 3-4 tt, at the base of which nestle the globose (50 p) perithecia 

 astomous and of tough, cellular texture. Asci fasciculate, cylmdric- 

 clavate. 40-50x10-12 ft. without paraphyses. Sporidia ovate-oblong, 

 8-14x4-5 //, hyaline, continuous at first, becoming yellow-brown and 

 uniseptate. The small stromata, after the perithecia have fallen, col- 

 lapse, and then much resemble a single cnpulate perithecium.

As the California fungus differs from the European only in the 

 yellow-brown, uniseptate sporidia, it seems better to regard it as the
