Harknessia affinis, E. & E.—On dead limbs of Liquidamber styra- 
cijlua , Plainfield, N. J., July, 1887. Geo. F. Mescliutt. Pustules valsoid, 
multilocular, covered at first with a white disk which is soon perforated 
in the center and is soon reduced to a white ring around the apex of the 
pustule; sporules elliptical, opaque, 20—25 x 12—15 /-q with a hyaline ped¬ 
icel about 25 ! l long and mostly enlarged below and an apical, awl-like, 
hyaline appendage about as long as the pedicel. Distinguished from II. 
caudata, E. & E., principally by its larger sporules. 
Pestalozzia kalmicola, E. & E.— On bleached dead tips of living 
leaves of Kalmia latifolio , Wilmington, Del., April, 1887. A. Commons, 
No. 481. Perithecia epiphyllous, minute, scattered on or near the living 
part of the leaf, arranged in subundulate, parallel, transverse lines; con- 
idia pale brown, 4-septate, fusoid, 18—22 x 5—7 with a small, terminal, 
hyaline cell, bearing three short (5—7 spreading, weak bristles, which, 
when well developed, are thickened at their tips. The living part of the 
leaf is separated from the dead by a narrow purplish-red line. This 
species is allied to P. decolorcita , Speg., but differs in its shorter, 4-septate 
conidia with shorter bristles. 
Pestalozzia adtjsta, E. & E.—On dead tips and margins of living 
leaves of cultivated plum trees, Newfield, N. J., July, 1887. Acervuli 
ampbigenous, minute, scattered, prominent, splueroid or subconic, black; 
conidia clavate-oblong, 4-septate, 12—15 x5— 6 /'- (colored part), the three 
medial cells pale brown, terminal cells hyaline, the apical one bearing a 
crest of 2—3 spreading, hyaline bristles 8—12 long; the tips and mar¬ 
gins of the leaves are of a light gray color and look as if scorched by fire. 
Pestalozzia discosioides, E. & E.—On living leaves of cultivated 
roses, Faulkland, Del., August, 1887. A. Commons, No. 611. Maculi- 
colous ; spots dirty brown, about 1 cm. in diameter, suborbicular; peri¬ 
thecia epiphyllous, erumpent-superficial, mostly elongated, hysteriiform, 
mm. long; conidia oblong-fusoid, slightly curved, 3-septate, yellow¬ 
ish-hyaline, the intermediate cells only a little darker than the terminal 
ones, 12—15 x 24—3 /•*, with a short (3—5 /*) oblique bristle at the apex or 
often arising from one side of the apex; basidia slender, about as long as 
the conidia. This seems most nearly allied to P. comjjta, Sacc., but is 
distinct from that species in its subhyaline conidia with much shorter 
terminal bristle. P. concentrica , 13. & Kav., and P. hyst&)'iiformis,B. &C., 
which are hardly distinct differ in their larger perithecia and larger 
conidia, with their intermediate cells brown. 
Pestalozzia cornifolia. E. & E.-On living leaves of Comas 
scricea , St. Gabriel, La., September, 1886. Langlois, No. 506. On round, 
husky brown spots 3—4 mm. in diameter, with a narrow, slightly-raised 
black border or line around which the leaf is slightly tinged with purple; 
perithecia punctiform, black, smooth, partly prominent, epiphyllous; 
spores oblong-elliptical, 4-septate, acute below, less distinctly so above 
and surmounted by a crest of three hyaline, spreading bristles 8—15 M
