times elongated and even imperfectly branched so as to form rudimen¬ 
tary basidia. 
Discula runcinata, n. s. On dead stems of Stephanomeria runci - 
nata, Helena, Mont., January, 1889; Bev. F. D. Kelsey, 133. Grega¬ 
rious or scattered, covered at first by the epidermis and then convex 
and closed, soon erumpent, and the upper part of the perithecia dis¬ 
appearing, leaving a broad opening above; of coarse cellular texture, 
150-200// in diameter. Sporules hyaline, continuous, oblong, curved, gen¬ 
erally more strongly so at one end, 18-23 by 3^-4//. The sporules and 
the perithecia also are those of a Vermicularia , only the hairs or bristles 
are wanting. 
Discella pilosula, n. s. On a decorticated maple, Lyndonville, 
N. Y., April, 1889, Dr. C. E. Fairman. Perithecia gregarious, ovate 
J to ^ millimeter ;n diameter, erumpent, superficial, black, rough, and 
sparingly clothed with short, spreading, pale, glandular hairs inter¬ 
mixed with a few black bristle-like hairs, at first closed, then with a 
broad opening above, the margin sublacerate dentate or subfimbriate. 
Texture of the perithecia subfibrous. Sporules cylindrical, curved, 
3-6-nucleate and either continuous or faintly 1-septate, brownish-hya¬ 
line, 10-16 by 2-2J//, the ends mostly abruptly mucronate-pointed and 
incurved. Basidia slender, simple, or sometimes branched, 25-30// 
long. This would come better under Amerosporium but for the 1-sep¬ 
tate sporules. The septum was only observed in the larger and more 
mature sporules and was then very faint, but there is no doubt of its 
presence, nor is it unlikely that after the specimens have lain in the 
herbarium a few years they may become three or more septate. 
Sporonema pallidum, n. s. On bleached spots on bare decaying 
wood of maple, Bidgeway, K. Y., May, 1889, Dr. C. E. Fairman, 58. 
Perithecia gregarious, erumpent, cespitose, J millimeter in diameter, 
multiradiate-cleft above or after the laciniae have disappeared, irregu¬ 
larly lacerate-cleft; at first closed. Sporules concatenate, 8-10 by 
2//, sub-cylindrical, hyaline, formed by constriction of the sporogeuous 
filaments. 
Glceosporium revolijtum, n. s. On living leaves of Bobinia 
pseuddcacia , Newfield, 1ST. J., August, 1889. Mostly on leaves of the 
terminal shoots. The margin of the leaf becomes yellowish green and 
revolute, then brown and dead. The oblong 12-15 by 3-44// spores 
begin to ooze out from the buried acervuli as the affected part begins 
to turn brown, soon becoming confluent and forming a flesh-colored 
coating on the surface of the leaf. In the early stage of growth the 
fungus has the aspect of a Taphrina. 
Glceosporium Ganadense, n. s. On living leaves of white oak, 
London, Canada, July, 1889; J. Dearness, 193. Spots amphigenous, 
irregular, subrotund, about 4 centimeter in diameter, pale rusty 
brown in the center, with a broad dirty brown border and tolerably 
definite margin above, more indefinite below. Acervuli scattered, be-
