lar, surrounded by the ruptured epidermis; spores subglobose, 
rough, .0012' in diameter, orange, with a thick hyaline epispore. 
Upper surface of leaves of Zedum latifolium. Summit of Mt. 
Marey. July. 
This seems to me to be quite distinct from U. Ledi A. & S. 
which is said to grow on the lower surface of leaves of Z. palustre 
and to form yellow spots. 
Perwermium Ceresrum Peck. 
Peridia large, convex, erumpent, irregularly confluent, forming 
brain-like convolutions, white, rupturing irregularly, the cells 
granulose, radiate-striate on the margin; spores variable, ovate 
elliptical or subglobose, rough, yellow, .0008' to .0OLI’ long. 
Trunks and branches of young pines, Pinus rigida. Center. 
May. 
This fungus forms excrescences from half an inch to two inches 
in diameter on the trunks and branches. On the smaller branches 
the excrescence puffs out equally on all sides of the branch. The 
outer bark comes off in large scales, revealing the bright yellow 
fungus which has produced the unseemly swelling. 
_ This plant was first detected by Mr. J. A. Lintner, who brought 
me specimens and made known its locality. 
Cysropus cusicus Str. 
Leaves of Canada thistle. Buffalo. Clinton. 
Resreria AurAntiaca Peck. (Plate 1, figs. 10-12.) 
Peridia deeply seated, cylindrical, fragile, soon lacerated, fuga- 
cious, white; spores subglobose, bright orange, about .001’ in 
diameter, with a thick hyaline epispore. 
Fruit of Amelanchier Canadensis. New Baltimore. Zabriskie. 
Keene. July. Also onthe fruit of Crategus. Buffalo. Clinton. 
It is remarkable that this species should have entirely escaped 
the notice of collectors hitherto and that it should now be detected, 
in one season, in three widely separated localities, by three differ- 
ent persons. ‘The color of the spores will enable this plant to be 
readily distinguished from its congeners. It seems to occur on the 
unripe fruit only. The Amelanchier leaves and fruit are inhabited 
by three species of Reestelia.
