improbable that they may finally become brown. This species occurs on 

 some of the specimens with no. 1199, A. F. 



It is not improbable that Sphceria sabalicola, E. & M., 1. c, is the same 

 as the S. sabaligera, B. & C, though the sporidia are only about half the 

 length given for that species. 



Heterosporium Allii, E. & M. -On withered leaves of Allium 

 vineale, Newfield, K. J., Aug. 1883. Hyphse erect, subcontinuous, nodu- 

 lose, olive-brown, about 50 x 9 /->-. Conidia oblong, fuscous, minutely 

 echinulate, 1— 3-septate, 20—33 x 9 u-. Differs from H. Ornithogali in its 

 olivaceous color and smaller conidia. 



Septoria PYROLiE, E. & M.— On living leaves of Pyrola secunda, 

 Red Rock, Lake Superior, June, Prof. J. Macoun, no. 20. Appears at 

 first in the form of little yellowish-white pustules scattered over the 

 lower surface of the leaf but visible also above. Soon the little nerve- 

 bounded areas of the leaf, in which these pustules appear, turn brown 

 bordered by the limiting nervelets now turned black, and in place of the 

 yellowish-white pustules appear little black perithecia, opening below 

 and filled w^ith filiform, 25—35 x f p- spores, obtuse at each end and only 

 slightly curved. 



Septoria consimilis, E. & M.— On cultivated lettuce, Geneva, N. 

 Y., July (Arthur), Newfield, N. J. On brown, dead, rather indefinitely 

 limited spots, i — 1 cm. in diameter. Perithecia, brown, subglobose, 

 innate, amphigenous, 90—100 /^-, scattered over the spots and visible on 

 both sides of the leaf. Spores filiform, multinucleate, shghtly curved, 

 ends mostly obtuse, 30—45 x 2— 2i /^-, hyaline. Diifers from 8. Lactucce, 

 Pass, in growing chiefly on spots, perithecia also a little larger and spores 

 a little longer but not distinguishable by its spores alone. 



Phyllosticta Gordoni^, E. & M.— On living leaves of G. lasian- 

 thuB, March. Spots dark brown, dry, occupying the ends and sides of the 

 leaves. Perithecia brown-black, subglobose, innate, slightly erumpent, 

 amphigenous, 120—140 Spores hyaline, oblong, nucleate, J2 x 3 



Phyllosticta Perse^, E. & M.— On living leaves of Fersea Caro- 

 linensis, March. Spots brownish-gray, covering the ends and sides of 

 the leaves. Perithecia brown-black, lenticular, innate-erumpent, epi- 

 phyllous, 150—300 long, 60—80 [J- broad. Spores oblong, hyaline, 

 nucleate, 3—8 x 1—33/^-. This and the preceding species with P. terminalis 

 E. & M., and P. Myricce, Cke., were collected in the same locality, and, 

 from the similarity in their mode of growth and the not very striking 

 difference in their other characters, they might be considered as varieties 

 of the same thing ; this, however, is a question that can not be definitely 

 determined without knowing the ascigerous forms to w^hich they all 

 probably belong. 



Pestalozzia peregrina, E. & M.— On dead leaves of Prinus Aus- 

 tridca, still hanging on branches cut off' last year, Newfield, N. J., May 

 1885. Acervuli hysteriform, covered at first, then partially erumpent.
