140 THIRTY-FIFTH REPORT ON THE STATE MUSEUM. 
This fungus forms more or less extensive patches over the sur- 
face of the wood. - The upper part of the flocci being covered with 
spores, the general aspect is somewhat similar to that of some 
species of Ceratium, e. g., C. hydnoides. The spores are so abun- 
dant that they hide the flocci and at first sight the whole fungus 
appears to be pale ochraceous. The smooth spores and white flocci 
separate this species from B. carnea, Schum.

Verticillium agaricinum, Bon., is closely related if not, indeed, 
the same species. 
VERTICILLIUM LACTARII, 7. sp. 
Flocci branched, white; branches either simple, opposite or 
verticillate, the ultimate ramuli tapering to the apex; spores 
apical, obovate or oblong-elliptical, smooth, colorless, -0006’— 
-0012' long, -0004'—-0005’ broad, usually with a slight point or 
apiculus at the base.

CERCOSPORA LEPIDII, 2. sp. 
Spots small, orbicular, grayish-brown or subcinereous, usually 
marked with faint concentric lines; flocci amphigenous, about 
-0016' long, single or two to three in a cluster, pallid ; spores very 
long, tapering upwards, slightly constricted at the septa, eight to 
nine-septate, -005’—-007' long, -0007'—-0008’ brqad in the widest 
part, greenish.

This is a very singular species. The fungus occurs on both sides 
of the leaf, but is more abundant on the upper surface. The 
flocci are short and thick and occasionally branched. The septa 
occur in the broad part of the spore, the upper part being much 
narrowed. Occasionally acell is divided by a longitudinal septum. 
CERCOSPORA DATURA, 1. sp. 
Spots suborbicular or irregular, varying in color from cinereous 
to reddish-brown, sometimes marked by irregular or flexuous 
elevated lines; flocci amphigenous, scarcely tufted, about equal 
to the spores in length; spores rather large, narrowed upwards, 
greenish, four to six-septate, -002’—.003' long, about -0005’ broad 
in the widest part.
