REPORT OF THE BOTANIST. 89 
ToRULA ALNEA 2%. Sp. ‘ 
Flocci tufted, erumpent, black, composed of nucleated joints 
about as long as broad, mostly slightly constricted at the septa, 
here and there strongly constricted. 
Dead branches of alder trees. Buffalo. Clinton. New Balti- 
more. Howe. Adirondack Mts. July. 
SporEnpDoNEMA Musce /7. 
Dead bodies of flies. Common. Autumn. 
This is Lmpusa Musce Cohn. It causes the death of the flies 
it attacks. 
SPoRIDESMIUM MORIFORME 1. sp. 
Spores collected in minute orbicular crowded black tufts, obovate 
or subelliptical, very obtuse; cells small, paler at the base where 
there is a subglobose, hyaline cell or peduncle nearly as broad as 
the spore which is .0013' to .0015' long. 
Decorticated wood of apple trees. Sandlake. November. 
The multicellular spores are suggestive of mulberries. 
GymnosporaNcium Junirert Lk. 
Bark of Juniperus Virginiana. New Baltimore. Howe. June. 
GyMNospoRANGIUM CLAVIPES Cooke & Pech. 
Sori mostly small and subrotund, sometimes confluent, convex, 
erumpent, orange; spores elliptical, obtuse, attached to a long hya- 
line peduncle which is gradually thickened toward the top, .0015’ 
to .0018’ long. 
Living branches of Juniperus Virginiana. New Baltimore. 
Howe. Bethlehem. May. 
This species differs from the preceding in its smaller sori and 
remarkably thickened peduncles. The apical part of the peduncle 
is sometimes wider even than the spore itself. The younger 
branches are slightly swollen where attacked by this fungus and 
the bark is scaly. When old the fungus becomes a thin shapeless 
gelatinous mass. The spores germinate at the extremities, each 
filament absorbing the contents of its own cell. 
Popisoma Fuscum Duby. 
Very young branchlets and “Cedar balls” of Juniperus Vir- 
gintiana. New Baltimore. Howe. Bethlehem and Helderberg 
Mts. May. 
This species is more abundant in the vicinity of Albany than its 
congener, ?. macropus. It has a darker color than that species 
and the spores and spore tufts are shorter.
