ostiolum, black; spores filiform, curved or flexuous, .0008 in. to .0012 
in. long. Dead stems of parsnip, Pastinaca sativa. Albany. May 
It is related to such species as S. Brunandiana, S. nebula, etc. 
Septoria hedeomina, ». sp. Spots none; perithecia scattered, 
minute, .003 in. to.004 in. broad, inconspicuous, black ; spores filiform, 
strongly curved, hyaline, .0012 in. to .0015 in. long. Dead stems and 
calyces of pennyroyal, Hedeoma pulegioides. Sandlake. May. 
Septoria Gei, &. dd D. Living leaves of GewmVirginianum. Guil- 
derland. July. 
Septoria Ostryx, 2. sp. Spots small, suborbicular, reddish-brown ; 
perithecia few, generally clustered in the center of the spot, brown or 
blackish-brown ; spores linear, strongly curved, obscurely three or 
four-septate, colorless, .0016 in. to .0024 in. long. Living leaves of 
hop hornbeam, Ostrya Virginica. Uelderberg mountains. July. 
Septoria lythrina, x. sp. Spots suborbicular or irregular, grayish- 
brown, often surrounded by a narrow blackish border; perithecia 
minute, epiphyllous, rarely amphigenous, blackish; spores filiform, 
slightly curved, .0008 in. to .0016 in. long. Living leaves of spiked 
loosestrife, Lythrum Salicaria. Newburgh. July. 
Septoria increscens, ». sp. Spots at first small, then larger, brown 
with an arid center ; perithecia minute, black ; spores filiform, curved 
or flexuous, .0012 in. to .0016 in. long. Living leaves of star flower. 
Trientalis Americana. Charlton. July. After the leaves are attacked 
by this fungus they turn yellow in patches and then brown. These 
discolored places increase in size till the whole leaf is dead. 
Septoria atropurpurea, 7. sp. Spots suborbicular, sometimes con- 
fluent, purplish-brown above, often centrally mottled by small whitish 
arid spots, paler below, purplish, with a brown or an_ ochraceous- 
brown center ; perithecia few, tendrils white ; spores filiform, straight 
or flexuous, .002 in. to .003 in. long. Living leaves of the large-leaved 
aster, Aster macrophyllus. Jamesyilie. Aug. The perithecia occur 
both on the arid central dots and on the colored parts of the spots. 
The peculiar character of the spots and the very long spores make 
this a very distinct species. 
Septoria Aceris, B. @ Br. Living leaves of sugar maple, Acer 
saccharinum. Sandlake. Aug. In our specimens the spots are very 
small, almost dot-like, arid, with a reddish-brown border and one to 
four perithecia. The spores are three-septate and strongly curved, 
but this difference is probably only varietal. 
Septoria Ludwigiz, Cke. Living leaves of water purslane, Lwd- 
wigia palustris. Charlton. July. In our specimens the spots have 
a purplish border and the spores are without nucleoli. Dr. Curtis 
long, ago distributed specimens of this species under the name 
Septoria Ludwigie B. & C., but so far as I know the characters of 
the species were never published. 
Septoria Mori, Zev. Living leaves of white mulberry, Morus alba. 
Charlton. July. 
Septoria Urticw, Desm. Living leaves of wood nettle, Laportea 
Canadensis. Charlton. July. 
Septoria Cornicola, Desm. Living leaves of red osier and alternate- 
leaved dogwood, Cornus stolonifera and C. alternifolia. Jamesyille
