SPHiERIACEiE IMPERFECTS COGNITS. 
In order to aid in practically reducing this “ appendix ” in 
Saccardo’s Sylloge still further than has already been done, we 
have examined specimens from the Herbarium of Schweinitz 
chiefly in the Berkeley Herbarium, with the following results : — 
4227. Nectria atrofusca (Schw.). Sphaeria atrofusca, Schw. Amer 
Bor. 1429. 
Asci clavate, stipitate, sporidia elliptical, uniseptate, hyaline, 
10-12 x 4 fj.. 
4321. Diplodia semitecta (Fries). Sphaeria semitecta, Fries • 
(Sphaeria panacis), Fries Scler. Suec. 319. 
Sporules elliptical, uniseptate, scarce constricted, dark brown, 
22-25 x 8 p.

4332. Fhoma surculi (Fr.). Sphaeria surculi, Schw. Amer. Bor. 1583.

elliptical, continuous, with a large central guttule, 20 x 8 fi.
