Pestalozzia consocia, 7. sp. 
Spots very large, sometimes occupying nearly half the leaf, irregular 
or angular, reddish-brown above, paler beneath ; acervuli amphigen- 
ous, minute, punctiform, black; spores oblong-fusiform, .0012 to 
.0014 in. long, .0003 broad, five septate, with four colored cells, .0009 
to.0011 in. long and asingle bristle at the apex. 
Living leaves of witch-hazel, Hamamelis Virginiana. Day. July. 
The species is associated with and occupies the same spots as 
Phyllosticta Hamamelidis. It may be a question as to which species 
causes the spots, though they are probably due to the Phyllosticta. 
Pestalozzia? campsosperma, 2. sp. 
Acervuli hypophyllous, minutely tufted ; spores fusiform, curved, 
triseptate, .0008 to .0012 in. long, .00028 to .00032 in. broad, with two 
colored cells .0005 in. long, the apical cell hyaline, conical, ending in 
an acuminate point, the lower cell tapering into the short pedicel. 
Dead leaves of balsam fir, Abies bulsamea. Adirondack mountains. 
June. 
This is a singular species. I have seen no terminal cilia and am not 
able to say whether they are entirely wanting or whether they are early 
deciduous. Thecharacters otherwise are so exactly like those of Pes- 
talozzia that I have, with some doubt, referred our plant to that genus. 
The curved spores are very characteristic of the species. 
Uredo Ledi, 4. & 8S. 
Living leaves of Labrador tea, Ledwm latifolium. Bergen swamp, 
Genesee county, and Sandlake, Rensselaer county. Jwue. 
The authors of this species remark that the leaves attacked by the 
fungus appear broader than usual. This peculiarity was very percep- 
tible in the Bergen swamp specimens, the usually involute margins of 
the leaves being almost wholly expanded or unrolled. The spores, 
which occur on the lower surface of the leaf and are partly concealed 
by its tomentum, are .0008 to .0009 in. broad. Their smaller size, 
different place of occurrence, and the different color of the spots readily 
distinguish this species from Uredo ledicola. 
Puccinia hastata, Che. 
Living leaves of Viola primulefolia. Riverhead. Sept. The typical 
form was discovered in Maine on leaves of Viola hastata. In our 
specimens teleutospores and stylospores occur on the same leaf and 
sometimes in the same sorus. 
Gymnosporangium clavarieforme, D. C. 
Branches of Juniper, Juniperus communis. Elizabethtown. May. 
This was in some instances associated with Gymnosporangium cla- 
vipes, the two occurring near each other on the same branch. The 
species is a rare one in this country, and has hitherto been reported 
from Maine only, 
Periconia pycnospora, /’res. 
Dead stems of melilot. Bethlehem. Apr.
