saccharinum, Racine, Wis., October, 1888. Dr. J. J. Davis, 59. Spots 
amphigenous, numerous, scattered, subangular, minute (mostly about 
1 millimeter iu diameter), greenish black, becoming darker. Acervuli 
hypopliyllous, minute, crowded in the spots, black above, so as to 
resemble minute peritkecia. Spores slender-cylindrical, more or less 
curved, hyaline, granular, becoming faintly 3-septate, 30-40 by 2£-3 ja 
erumpent in small wliite heaps which soon spread out into a small 
membranaceous patch like a minute white Corticium. This can not 
easily be mistaken for Glceosporium aceris , Cke. or G. acerinum , West. 
Hainesia borealis, n. s. On Galium boreale , Hauiloops, British 
Columbia, July, 1889. Dr. John Macoun, 156. Acervuli hypopkyl- 
lous, scattered, suborbicular, erumpent, J to J millimeter iu diameter, 
subgelatiuous, yellowish-hyaline, depressed-hemispherical, with a nar¬ 
row black linear margin formed from the ruptured epidermis of the 
leaf. Spores suballantoid, 5-7 by 1//, faintly 2-nucleate, slightly curved, 
borne on fasciculate, more or less branched basidia, 20-25 by 1//. 
Cryptosporium nubilosum, n. s. On dead or partly dead leaves 
of Carex (Pennsylvania ?) Newfield, N. J., 1879. Sent also from Mon¬ 
tana by Mr. Anderson (344) on an allied species of Carex. Acervuli 
innate, scarcely erumpent, black, 80-110// in diameter, showing by 
translucence through the epidermis, gregarious in bands across the leaf 
or seriate. Sporules lunate-fusoid, 15-20 by 2J//, hyaline , faintly nu¬ 
cleate. 
Nzemasfora microsperma, n. s. On bark of Acer saccharinum , 
London, Canada, August, 1889. J. Dearness, No. 562. Sporiferous 
cavities confluent for 1-2 centimeters between the laminae of the bark, 
purplish black, the minute, ovate, or elliptical 2-24 by 14-2 /a spores 
bursting out in copious cherry-red masses and cirrki through cracks in 
the bark. Differs from C. difformis , Sz., in its smaller spores on basidia, 
12-15 by 1 i M .. 
Pestalozzia affinis, n. s. On fallen leaves of “ Japan Chestnut,” 
Lafayette, La. Acervuli innate, erumpent, on both sides of the leaf, 
but more abundant below. Spores acutely elliptical, pale, 15 by 5// 
(about 12//) between the extreme septa, 4-septate, with a single ob¬ 
lique bristle about 7// long at the apex and borne on a pedicel shorter 
than the spore. The spores ooze out in small black heaps, which are 
as usual often subconfluent-diffused. This differs from P. pallida , E. 
& M., in its broader spores and in lacking the prominent septa of that 
species. 
Pestalozzia flagellifera, n. s. On branches of Gomptonia aspleni - 
folia, killed by lire a few weeks ago, Newfield, N. J, June 10, 1889. 
Pustules numerous, subcuticular, raising the epidermis into little tuber- 
culiform pustules which become slightly ruptured above and have a 
dark gray nucleus. Spores abundant, oblong, slightly curved 1-sep- 
tate, yellowish-hyaline, 9-12 by 3//, on stout basidia, about as long as 
the spores with a single long (25-35//) undulate, hyaline bristle ris-
