innate, small, about 30// in diameter, visible on both sides of the leaf, 
but more prominent and mostly opening on the upper side, pale, seated 
on rusty yellowish, or reddish brown, elongated, narrow, subcontinent 
spots. Sporules cylindrical, continuous, 6-12 by 1-1^//. The leaves 
finally become rusty brown and dead, especially at the points. 
Sept or i A leucostoma n. sp. —On living leaves of Fraxinus ameri- 
cana. Urmeyville, lud., August, 1890. (E. M. Fisher, No. 136.) Spots 
reddish brown, irregular in shape, 1J-J CU1 in diameter, or by continence 
occupying a large part of the leaf, surrounded by a yellow, shaded 
border about the same on both sides of the leaf. Peritliecia scattered 
on the spots, large, 200-230// in diameter, lenticular, amphigenous, 
but more prominent on the upper side of the leaf, pierced with a large, 
round, white margined opening above. Sporidia fusoid, mostly strongly 
curved,nucleate, becoming about 3-pseudoseptate, 20-30 by 2.J//. Seems 
to differ from 8. elceospora Sacc. in its much larger peritliecia and 
strongly curved sporidia. 
Septorta pimpinellje n. sp. —On leaves of Pimpinella integerrima. 
Winona, Minn., August, 1888. (J. M. Holziuger.) Peritliecia amphig¬ 
enous, scattered, not on any spots, erumpent, 120-130// in diameter. 
Sporules short (15-20//),curved, continuous, hyaline, about 1J// thick 
at the broader end, resembling the sporules of a Phlyctcena. Some of 
the peritliecia contain short, oblong fusoid 2-nucleate sporules 6-9 by 
2J//, hyaline ( Phyllosticta sp.). The Septoria has the sporules shorter 
than in any of the other described species on Umbelliferce. 
Septoria rumicis n. sp. —On leaves of Bumex sp. Winona, Minn., 
August, 1888 (J. M. Holziuger), and Champaign, Ill., September, 
1889. (M. B. Waite.) Spots amphigenous, grayish brown, becoming 
rusty brown and paler in the center, with a narrow, slightly raised 
border surrounded by a dark-shaded border while the leaf is fresh, 
3—4 mm in diameter. Peritliecia punctiform, brown, scarcely visible, 
buried in the substance of the leaf with only the minute apex showing, 
most distinct on the lower surface of the leaf, but also visible above. 
Sporules cylindrical, curved, obtuse, continuous, faintly nucleate, sub¬ 
equal, 15-25 by 1J-2//. 
Phlyct^na andersont n. sp. —On dead slims of Arabis holboellii 
and Draba sp. Sand Coulee, Cascade County, Mont., July, 1888. (F. 
W. Anderson.) Peritliecia gregarious on pale spots, subcuticular, 
conic-globose, at length collapsing, raising the epidermis into little 
black pustules, having the aspect of a Sphcerella. Sporules fusoid 
arcuate hyaline, acute at each end, continuous, 12-15 by 2i//. Some 
of the pale spots on which the peritliecia are seated are tinged with 
rose color. 
Cylindrosporium staciiydis n. sp. —On Stachys palustris. Cham¬ 
paign, Ill., September, 1888. (M. B. Waite.) Spots amphigenous, small 
(1—2 mm ) rusty brown, becoming nearly black, with a whitish center, sub- 
augular and tolerably well defined. Acervuli small, innate, slightly
