biguttate, oozing out and blackening the epidermis, 70-80x6-8 yp. 
On old weathered cornstalks (Zea Mays). Auburn, Ala,

This is a very striking species. The long dark. spores can be 
distinctly seen with a hand magnifier scattered over the epider- 
mis. The gross appearance is much like that of Diplodia Zeae 
Lev., but it is easily distinguished by the much larger spores. 
HETEROSPORIUM SAMBUCI 0. sp. 
Effused, covering considerable areas with a black velvety tomen- 
tum; hyphae long, 100-200 yp, dark fuscous, erect, often fascicled, 
branching, septate, nodular, bearing spores pleurogenously at the 
enlarged nodes; spores oblong, dark fuscous, 3-septate, surface con- 
spicuously roughened by minute tubercles, about 20-30x5 p.

Macropuoma Diospyrt n. sp. 
Thickly scattered over large indeterminate areas; perithecia — 
buried, elevating the epidermis in prominent pustules, at length 
partially erumpent, surrounded by the ruptured epidermis, large, 
opening by a distinct ostiolum, dark brown, of soft cellular struc- 
ture, reaching 200 »; spores cylindric, sometimes slightly curved, 
ends abruptly pointed, faintly tinged with olive when seen in mass, | 
contents homogeneous, not guttate nor granular, about 20x3 BS
