Septoria Drummondii, n. sp .—On leaves of Pldox Drummondii. 
London, Canada, September, 1891. (Dearness, No. 820.) Differs from 8. 
divaricata E. & E. on Phlox divaricata (this journal, Vol. v, p. 151) 
in the perithecia being scattered thickly over the entire surface of the 
leaf, and not on any definite spots. Perithecia black, subprominent, 
100 [x in diameter. Sporules nearly straight, nucleate, 35-50 xlJ-2^, 
rather narrower at one end. 
Hendersonia geographica, n. sp. — On fallen and decaying chest¬ 
nut leaves. Newfield, N. J., April 4, 1891. Acervuli gregarious, on 
pale spots, dark brown, flattisli, J-J mm in diameter, mostly on the nerves 
of the leaf, and forming a kind of network, reminding one of Asteroma 
geograpliica , Fr. Sporules oblong-fusoid, pale brown, 3-septate, the 
terminal cells hyaline, acutely conical and 4-5 long, the colored part 
10-12 x 3-3J il. Pedicels filiform, about 15 ;i long, sometimes remaining 
attached to the sporule. Terminal cell prolonged into a short, subulate 
beak, or oftener simply narrowed into a subulate point. The terminal 
cells are finally deciduous. Differs from P. nervalis , E. & E. (to which 
it bears a strong resemblance) in its smaller, 3-septate sporules and 
larger acervuli. 
Glceosporium catalp^e, n. sp. — On living leaves of Catalpa bignoni- 
oides. Wilmington, Del., August, 1891. (Commons, No. 1804.) Spots 
orbicular, 2-3 mm in diameter; definite, reddish-brown, paler in the cen- . 
ter. Acervuli minute. Spores oblong, hyaline, continuous, 2-nucleate, 
10-15 x 3-5 p, erumpent on the upper side of the leaf in small, yellow¬ 
ish heaps. 
Glceosporium decolorans, n. sp .—On leaves of Acer rubrum. Lon¬ 
don, Canada, August, 1891. (J. Dearness, No. 813.) Occupying the areas 
between the main veins of the leaf, and causing large brown spots which 
occupy the entire surface of the leaf except a narrow strip along each 
side of the midrib and its main branches. Acervuli numerous, small, 
erumpent on the lower side of the leaf. Spores oblong-elliptical, hya¬ 
line, 5-8 x 2J-3 p. Very destructive to the leaves. 
Melanconium magnolije, n. sp. — On dead trunks of Magnolia glauca. 
Newfield, N. J., June, 1891. Acervuli sunk in the bark, ovate-conical, 
l-ljmm in diameter, substratum pale. Conidia obovate, pale olive 
brown, with a hyaline margin and a large nucleus, 12-15 x 9-11 p on 
stout (4 p thick), simple or branching, obscurely septate basidia, 50-75 p 
long, erumpent in masses or black cirrlii, like coarse black hairs or 
black wool. 
Pestalozzia lateripes, n. sp. — On dead legumes of Cassia Cha- 
mcecrista. Newfield, N. J., September and October, 1891. Perithecia 
pustuliform or subhysteriiform, about J mm in diameter, with a large, 
irregular opening above, sometimes with an elongated slit, as in Hyster- 
ium. Sporules clavate-cylindrical, yellowish brown, 3-septate, theupper 
cell rounded above with a hyaline, subconical tip bearing at its apex a 
3-parted crest of three, spreading slender bristles 15-20 p long, the lower
