and the bristles are shorter, stouter and purplish. These give a pur- 
plish tint to the appearance of the spike whereby this form can be 
readily distinguished from the ordinary one. The flowers make an 
approach to a verticillate arrangement toward the base of the spikes 
after the manner of S. verticillate. 
Aspidium fragrans, Sw. This rare fern was found in limited quan- 
tity on the rocks at Edmonds ponds. This is the second locality in the 
Adirondacks in which it has been found. Here also, as at Lake 
Avalanche, it was associated with Woodsia hyperborea, a fern of no 
common occurrence in our State. Aspidium aculeatum v. Braunti 
also occurs sparingly in this locality. 
Pelleea gracilis, Hook. At Edmonds ponds, about half way up the 
cascade opposite the Cascade House, is a limited mass of calcite sur- 
rounded by the ordinary rock of the mountains. The limestone affords a 
congenial habitat for this dainty little fern and here it grows in great 
luxuriance and profusion. This mass of calcite appears “to render this 
limited locality inhabitable by the fern, for I did not find it extending 
beyond this isolated station which is the only one in the interior moun- 
tain district in which I have observed this fern. 
Phegopteris polypodioides, Fee. A dwarf yet fertile form of this 
fern with the frond only two or three inches long was found growing 
in crevices of rocks in the Adirondack mountains. 
Cheilanthes vestita, Sw. A second station forthis fern in our State 
has been found near Poughkeepsie. The one on New York Island is 
said still to exist but the plants occupy a very limited area. 
Agaricus virescens, Pk. (Report 25, p. 74.) The name of this 
species being preoccupied I would substitute for our plant the name 
Agaricus viriditinctus. 
Polyporus radiatus, /r. One form of this species has the margin 
yellow, in another form the pileus is uniform in color. 
Polyporus Jucidus, #r. Specimens sometimes occur in which there 
are two distinct strata of pores. 
Septoria Rubi, 2. é C, var. alba, Pk. In this variety the spots are 
small and white, and bear but few perithecia. It occurs on Rubus 
villosus and R. Canadensis. 
Sporocybe Persice, Fr. ‘This fungus should be placed in the genus 
Spheronema. The spores are produced at the base, not at the apex 
of the fungus. 
Haplographium apiculatum, P%. This species was first found in- 
habiting an insect gall on leaves of witch hazel, Hamamelis Virginica. 
It has since been found on the lower surface of the leaves themselves, 
on dry suborbicular brown spots. The flocci often have two or three 
swollen nodules in the upper part, from which strings of spores grow. 
In such cases the strings of spores appear to bein verticils when viewed 
with a low magnifying power. 
Spheria Coryli, Batsch. var. spiralis, Pk. This variety differs from 
the ordinary form only in having the ostiola spirally coiled in about 
two volutions. All the ostiola on the perithecia of a host plant are af- 
fected in the same way, that is, I do not find on any given leaf or leaves 
of an affected plant some ostiola straight and gome coiled, but all are 
straight or all are coiled.
