or brown with age, whitened by the fungus below ; spores oblong or 
elliptical, generally binucleate, .0003 to .0004 in. long, .00016 broad. 
Living leaves of hickory, Carya alba. Albany and Greenbush. 
June and July. 
Sometimes the spots are angular, being limited by the veinlets of 
the leaf. In this species and in the next one I have not seen the 
spores septate, but suspecting that the nuclei indicate septa in more 
mature specimens, I have referred the species to this genus for the 
present. They may belong rather to Cylindrium or Fusidium. 
Ramularia angustata. 
Spots small, orbicular, sometimes confluent, pale greenish-yellow, 
becoming reddish-brown or brown, frosted on the lower surface by 
the fungus ; flocci minute ; spores narrowly fusiform or subeylindrical, 
-0003 to .0004 in. long, about .0001 in. broad, often containing two 
or three nucleoli. 
Living leaves of pinxter plant, Azalea nudiflora. Central Bridge 
and Carlisle. June. 
The very narrow spores suggest the specific name. 
Ramularia lineola. 
Spots suborbicular, sometimes confluent, brown, concentrically 
lineolate ; flocci obscure, tufted, hypophyllous ; spores slender, 
cylindrical, obtuse, .0005 to .0008 in. long, often uniseptate. 
Living leaves of dandelion, Taraxacum, Dens-leonis. Greenbush. 
July. 
The fungus is so minute that it is scarcely visible to the naked eye. 
Sporotrichum larvicolum. 
Flocci slender, simple or branched, forming a continuous, dense, 
soft, white or yellowish stratum coating the whole matrix ; spores 
abundant, minute, globose, .00008 to .00012 in. broad. 
Dead larvee lying on the ground under alders. Adirondack moun- 
tains. July. 
The larvee were very numerous and, but for the check imposed 
upon the increase of the species by the attacks of this fungus, they 
would probably in a short time have completely defoliated all the 
alders in that locality. In some specimens the fungus spores were so 
abundant that the surface of the stratum had a pulverulent appearance.
