Haplosporella viticola, CJce. Sf Mass. 
Erumpent, more or less in longitudinal series, pustules elliptical, 
composed of ten, or more, rather large, dull black, subglobose 
perithecia, scarcely pierced, and with the habit of Botryosphceria. 
Sporules large, oval or broadly elliptical, continuous, yellow brown 
(30-35 x 10-15 p), basidia thick, about as long as the sporules. 
On stems of Ampelopsis. Kew Gardens. 
Leptothyrium berbesridis, Clce. Sf Mass. 
On both surfaces of fading leaves, minute, punctiform, black, 
scattered, discoid. Sporules cylindrical, rounded at the ends, con- 
tinuous, hyaline (8-9 X 1J-2 p). 
On leaves of Berberis vulgaris. Oxford {Baxter). 
Excipula ramicola. Clce. <$■ Mass. 
Perithecia superficial, scattered or gregarious, disciform, convex, 
black, rather small (J mm.). Sporules cylindrical, obtuse, 
25-30 x 4 p, hyaline, multi-nucleate, perhaps at length multi- 
septate {Excipulina), on short simple basidia. 
On decorticated branches of Acer obtusatum. Kew. 
Coniothecium viticolum, Clce. Sf Mass. 
Tufts erumpent, hemispherical, black, rather compact, loosely 
gregarious, conidia rounded, subglobose, variously agglutinated

versely divided, brown (20 X 8-10 p). 
On twigs of Ephedra andina. Kew. 
Camarosporium syringae, Clce. Sf Mass. 
Somewhat gregarious on bleached spots. Perithecia subcuti- 
cular, elevating and at length piercing the epidermis, subglobose, 
black, papillate. Sporules elliptical, not constricted, triseptate,

X 8-10 p).
