170. Septoria musiya, Pk. 35th Rep. N. Y. State Mus., p. 138. 
“Spots small, numerous, angular, brown, usually obscurely mottled 
by minute angular patches of paler color ; perithecia few, epiphyllous, 
depressed, black or blackish ; sporules cylindrical, slightly curved, color¬ 
less, sometimes obscurely triseptate, 30—45 P long. On living leaves of 
Populus monilifera. Albany, N. Y., July. This species differs from S. 
Populi , Desm., in the character of the spots, which are variegated like 
mosaic work, and in the septation of the spores.” 
171. Septoria Calystegee, West. 
“Spots small, subrotund, brown, slightly raised, so as almost to 
resemble a stroma; perithecia 1—3, innate, mostly hypophyllous, pale, 
opening by an apical pore; sporules cylindrical, slightly curved, 30—45 
x 4—5 rounded at each end, 3—5-septate and multinucleate, hyaline.” 
Sacc. Syll. Ill, p. 537. On living leaves of Calystegia septum. Albany, 
N. Y. C. H. Peck, in 35th Rep., p. 137. 
172. Septoria glauca, Ck. Rav. F. Am., No.'93. 
Spots cinereous, with a narrow, darker border, 2—5 millim. in diame., 
irregular in shape ; perithecia sublenticular, thickly scattered over the 
spots. The specimen in the collection referred to is (in my copy) barren. 
173. Septoria punicei, Pk. 38th Rep. N. Y. State Mus., p. 97. 
“ Spots 2—4 lines broad, indefinite, blackish-brown above, brown or 
reddish-brown below ; perithecia hypophyllous ; sporules very long, flex- 
uous, filiform, white in the mass, 10—15 P long. On living leaves of 
Aster puniceus. Caroga, N. Y., July.” 
174. Septoria fumosa, Pk. 38th Rep., p. 98. 
“Spots angular or irregular, often confluent, smoky-brown or grayish- 
brown with a darker margin; perithecia epiphyllous, 7—9 p in diameter, 
black; sporules filiform, 30-50 long. On living or languishing leaves 
of Solidago Canadensis. Albany, June. The sporules are shorter than 
those of S’. Virgaurece.” 
175. Septoria Gei, Rob. & Desm. Sacc. Syll. Ill, p. 510. 
“Spots orbicular or irregular, pale brown, becoming dry and cinere¬ 
ous in the center, with a dark border; perithecia epiphyllous, numerous, 
dark brown, hemispheric, collapsing; sporules filiform, acute at each 
end, 30x14,", continuous, subhyaline.” On Geum Virginianum. Guil- 
derland, N. Y., July. Peck, in 33d Rep., p. 25. 
176. Septoria Epilobii, West. Sacc. Syll. Ill, p. 513. 
Spots olivaceous, small (one millim.), scattered, becoming whitish 
above, with an obscure, darker border, and generally surrounded with a 
purplish stain; perithecia innate, scarcely visible; sporules nearly 
straight or only slightly curved, 20—35 xll p, yellowish-hyaline, contin¬ 
uous, very obscurely nucleolate. 
This description, drawn up from specimens on Epilobium coloratura , 
collected in Wisconsin by Trelease & Pammel and in Delaware by A. 
Commons, differs from that in Sylloge in the shorter sporules and spots, 
not limited by the veinlets, but orbicular or nearly so.
