conidia) 150—220 micr., by 9 —13 micr. in diameter; conidia 
oval hyaline, continuous, granular within, 15 x 21—29, mostly 
15 x 27 micr. On Celtis occidentalism Manhattan, Kansas. 
The fungus is found associated with Phytoptus (an undescribed 
species) on Hackberry (Celtis). The distortions caused by the 
insect, or perhaps by both insect and fungus, consist of a multitude 
of abnormal, more or less abortive branchlets that form a compact 
' knot, \ to 11 inches in diameter; a few of the branchlets are pro¬ 
longed a few inches and themselves bear smaller knots of similar 
structure. The abortive branchlets have excessively numerous 
buds all infested by the insect and covered by the fungus. The 
conidial stage is found associated with the perithecia and some¬ 
times even extending out on the twigs to the under side of the 
leaves. The perithecia are found in the spring but do not mature 
their spores till late fall or winter. 
Septoria CASSiiECOLA, Ke t U. & Sjvingle. — Perithecia occupying 
indefinite portions of the languishing cotyledons of Cassia chamae- 
crista, abundant but not crowded, amphigenous, small, sub-im¬ 
mersed, black, 70—90 micr. in diameter. Sporules filiform, 
straight or slightly curved, continuous, hyaline, variable, 20—40 
x J—IJ, often 36 x 1| micr. May 1888, Manhattan, Kansas. 
Colletotrichum CARPOPHiLUM, Kell. & Swingle.—Spots de¬ 
pressed, orbicular, often confluent and occupying the greater 
portion of the lower side of the fruit, J—1 cm. in di¬ 
ameter. brownish or dusky, centre of spot pallid, usually sur¬ 
rounded by a reddish margin. Acervuli numerous, crowded 
black, applanate, variable in size. Bristles rather abundant, 
black, dusky, usually curved more, or loss, regularly tapering from 
base to the acutish point, 60—100 micr. in length, 5 — 6 micr. in 
width at base. Sporules arcuate, fusoid, acute at both ends, 
16—22 x 2J —4. Mostly 18—21 x 3 —3J, nucleate. On living- 
fruit of Astragalus Caryocarpus, May and June, 1888, Man¬ 
hattan, Kansas. 
Cercospora Ceanotht, Kell. & Swingle.—Spots reddish-brown 
or russet, circular or subcircular, seldom confluent, abundant, 
equally distinct on both sides of the leaf, 1—5 (mostly 2—4) mil¬ 
limeters. Hyphse pale brown, continuous or very rarely septate, 
simple, often nucleate, subnodulose above, hypophyllous some¬ 
times amphigenous, densely fasciculate, 20—36 x 3-—4J, 
forming minute tufts which are congregated in the centre of 
the spot. Conidia curved or straight, narrowly cylindrical or
