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. Braunii 

 also occurs sparingly in this locality. 



Pellaea 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 forthisfern 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, Ph. (Report 25, p. 74.) The name of this 

 species being preoccupied I would substitute for our plant the name 

 Agaricus viriditinctus. 



Polyporus radiatus, Fr. One form of this species has the margin 

 yellow, in another form the pileus is uniform in color. 



Polyporus lucidus, Fr. Specimens sometimes occur in which there 

 are two distinct strata of pores. 



Septoria Rubi, B. & C, var. alba, Ph. In this variety the spots are 

 small and white, and bear but few perithecia. It occurs on Rubus 

 villosus and R. Canadensis . 



Sporocybe Persicae, Fr. This fungus should be placed in the genus 

 Sphaeronema. The spores are produced at the base, not at the apex 

 of the fungus. 



Haplographium apiculatum, Ph. This species was first found in- 

 habiting an insect gall on leaves of witch hazel, Haviamelis 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 be in verticils when viewed 

 with a low magnifying power. 



Sphseria Coryli, Batsch. var. spiralis, Ph. 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 some coiled, but all are 

 straight or all are coiled.
