woven hyphae, gregarious, superficial, globose-depressed, and finally 

 umbilicate-collapsing, 100-150 fi % texture minutely angular-parenchy- 

 matic. Asci fasciculate, oblong-clavate, briefly stipitate, rounded above, 

 65-70x20-28 pt, without paraphyses. Sporidia 2-3 -seriate, oblong- 

 cylindrical, slightly curved, hyaline, 3-6-septate, and when fully de- 

 veloped, with two or more cells divided by a longitudinal septum, 

 sometimes slightly constricted at the septa, 1 6-25 x 3-6 /Jt. Var. major, 

 on leaves of Magnolia glauca, has the perithecia and sporidia larger, 

 the latter 30-40 x 7-8 /jl, and 6-9-septate.

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

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

 ish, surrounded and nearly hidden by tufts of erect, brown hairs. Asci 

 cjdindrical, 8-spored. Sporidia oblong, hyaline, becoming uniseptate.

Stromata flat, convex, becoming concave, small (250-300 ju 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 60-130 x 

 3-4 /i, at the base of which nestle the globose (50 /i) perithecia 

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

 clavate, 40-50 x 10-12 /^, without paraphyses. Sporidia ovate-oblong, 

 8-14 x 4-5 //, 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 cupulate perithecium.

As the California fungus differs from the European only in the 

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