150 
across; the leaf in these parts being slightly blackened. Sporules spi- 
culiform, attenuated to a point at one end and subtruucate at the other, 
faintly nucleolate, 20-30 by 1J//, mostly less than 25/r long. Differs 
from any of the four species on Lathyrus in the Sylloge in its shorter, 
spiculose sporules. Septoria vicicc , West, also has longer and thicker 
sporules. The general appearance is that of an erumpent Sphccrella. 
Perhaps the spermogonia of Sphccrella lathyrina , B. & C. 
Septoria intermedia, n. s. On Solid ago (junceal ), Racine, Wis., 
June, 1888 (Davis No. 25). Spots small (L millimeter), scattered, sub¬ 
confluent dull-white, with a dark purple shaded border. Sporules nearly 
straight, hyaline, nucleolate 35-25 by 1-1J//. Has the general ap¬ 
pearance of Septoria cttropurpurea, Pk., but is distinguished by its much 
shorter spores as well as different host. 
Septoria physostegi^e, n. s. On leaves of Physosiegia Yirginiana , 
Racine, Wis., September, 1888. Dr. J. J. Davis, 4. Spots amphigen- 
ous, small (1 millimeter), dirty white, with a shaded purplish border. 
Sometimes several of the small white spots are included in a larger 
brown spot. Sporules filiform, nearly straight, 20-27 by 1-1 \p.. S. 
bruncUce , Ell. & Hoi w. is on larger rusty brown spots and has longer 
sporules. 
Septoria astericola, n. s. On Aster cordifolius , Magnolia, Mass. 
Miss Clarke; Delaware, Commons,- 723 and 724; Wisconsin, Davis. 
Spots amphigenous, dark brown, subindefinitely limited, bounded by a 
broad yellow border, the brown central part 3-4 millimeters across. 
Perithecia innate, finally partially erumpent above, numerous, scattered, 
small (75//), scarcely visible in the earlier stages of growth, light brown. 
Sporules slender, nearly straight, nucleate, 30-45 by 1-1 J//. Differs 
from S. atropurpurea , Pk. in its yellow bordered spots and shorter, nar¬ 
rower sporules. 
Septoria prenanthis, n. s. On leaves of Prenanthes , Racine, 
Wis., August, 1888, Dr. J. J. Davis, 20. Spots scattered, suborbicular, 
dull white, with a purple border 2-3 millimeters in diameter, thin. Peri¬ 
thecia amphigenous, scattered on the spots, suberumpent, yellowish. 
Sporules filiform, slightly curved, continuous, 15-22 by 1-1 J//. 
Septoria asclepiadicola. Jour. Mycol., IV, p. 44. The sporules 
are mostly only H/r thick instead of 2-2J//. The same thing has been 
sent from Missouri on Asclepias rubra , Demetrio, 215. 
Septoria commonsii, n. s. On leaves of Gnicus altissimum , Faulk- 
land, Del., August, 1885. A. Commons, 137. Spots dark brown with a 
whitish center, round, 2-4 millimeters diameter, obscured below by the 
tomentum of the leaf. Peritheciaepiphyllous, minute, clustered, black, 
subprominent. Sporules subspiculose, slightly curved, continuous, 
nucleolate, 25-40 by 1-1^//. S. cirsii , NieSsl., is said to have sporules 
40-80 by 11-2// and 8-12-septate. The specimens labeled S. cirsii , 
Niessl., in De Thiimen’s Austrian Fungi, 090, which are sterile, have the 
spots concentrically marked and have no white center.
