PHLE0SP0HAS OF NORTH AMERICA. 
8', 
nucleate, becoming 1-septate, 45—75 x 2i—3 p. This is really a Phleos¬ 
pora , on account of the very imperfect perithecia (if they can properly be 
called perithecia). Really “acervuli” would be more nearly correct, as 
there are no proper perithecia either in the Wisconsin specimens or in 
any of the specimens of S. Aegopodii in the various European Exsiccati 
examined. 
188. Septoria Helenii, E. & E. On leaves of Helenium autumnale. 
Racine, Wis., June, 1887. Dr. J. J. Davis. 
Spots amphigenous, 2—4 millim. in-diameter, dark, becoming dirty 
white, with a dark, slightly raised border; perithecia about 100 in diam¬ 
eter, of pale, parenchymatous structure, epiphyllous, the minute, black, 
perforated, papilliform ostiola showing as black specks thickly scattered 
on the spots; sporules vermiform, 20—35 x 2 Z-'-, 1—3-septate. S. Helianthi , 
E. & K., has larger, ferruginous spots without any raised border and 
much longer sporules acuminately attenuated at each end and 3—5- 
septate. 
In the 23d Rep. N. Y. State Mus., pp. 54 and 55, the following 
Septorias are mentioned : 8. plantaginicola , B. & C.; 8. Liriodendri , B. & 
0.; S.Vitis, B. & C.; S. destruens , West.; S. sanguined , Desm. Of these, 
the first is probably the same as 8. inconspicua , B. & C.; the others may 
be considered doubtful. 
Septoria viticola , B. & C., in Rav. F. Am., No. 26, should be Sacidium 
viticolum. See Grev. VI, p. 136. 
Note.—I n the preceding list, Ncs. 159—188 have been added since 
Dr. Martin’s death. 
Prof. Saccardo having transferred a number of species heretofore 
described as Septorias to the genera Phleospora , Phabdospora and Phlyc- 
tcena , they will be found under these heads. 
Phleospora, Wall. Sylloge III, p. 577. 
Perithecia innate, imperfect; sporules hyaline, elongated-fusoid, 
thick, 2-pluriseptate—growing on leaves. A name illy chosen to distin¬ 
guish them from the Septorias , as the sporules are exuded or flow out 
in both. 
1. Phleospora Aceris (Lib.) Sacc. Sylloge III, p. 577; Ascochyta 
Aceris, Lib.; Septoria acericola, Desm.; Septoria Aceris, B. & Br.; Ellis, 
N. A. E., 346. 
Spots tawny or pale yellow, subangular, limited by the veinlets, often 
coalescing, 3—5 millim. in diameter; perithecia brown, flattened, innate, 
hypophyllous, 150—200 ! J - in diameter; sporules hyaline, subfusiform, 
ends obtuse, 3-septate. not constricted, 20—30 x 3—5 p. On leaves of 
Acer and Negundo aceroides. Massachusetts and California. 
2. Phleospora Celtidis, E. & M. 
Spots gray-brown, gray in the center, irregular, coalescing; peri¬ 
thecia dark brown, subglobose, prominent, few in a spot, amphigenous, 
200—275 !>■ in diameter; sporules subhyaline, subfusiform, ends subacute, 
curved, 6—8-septate, 70—80 x 8—10 p. On leaves of Celtis occidentalis. 
Missouri.
