REPORT OF THE BOTANIST. 57 
BoLetus ALBus Pk. 
This is another Boletus of rare occurrence. When young the tubes are 
white, but they at length become yellow or ochraceous-yellow. The flesh is 
white and the plant when fresh emits a fetid odor. 
BoLetus SUBTOMENTosSUS L. 
A form of this species occurs in which the costz of the stem anastomose in 
such a way as to form large but rather obscure reticulations. Is it B. danatous 
Rost.? Another form having the pileus and stem darker-colored than usual 
occurs on much decayed prostrate trunks of trees and about old stumps. The 
chinks of the pileus are sometimes whitish. 
Bovetus arrinis Ph. 
A fine variety of this species was found at Gansevoort, in which the pileus 
was beautifully mottled by small yellowish spots. It merits the name var. 
maculosus. 
BoLetus Mopestus Pi. 
This rare species sometimes has the flesh of the pileus yellowish. The 
stem is minutely scurfy or furfuraceous. 
PoLYPORUS CHRULEOPORUS Ph. 
A form of this species was found at South Corinth, in which the whole plant 
was grayish-blue except the flesh which was white.

Potyporus Rurprpium Berk. 
There is a slight viscidity to the pores of this species. The pileus fades 
with age. 
PoLyporus sPUMEUS /7. 
A large form of this plant, with pilei sometimes six or eight inches ‘across, 
occurred at Brewerton. 
PoLYPORUS BOREALIS F’, 
This sometimes occurs on hemlock stumps. It then differs from the form 
on spruce in haying the pileus broader, wholly white and strigose-hairy or 
fibrous-hispid. 
PoLyporus voLvatus Ph. 
The form recently published under the name Polyporus obvolutus Berk. & 
Cke. is not specifically distinct from this species, according to specimens 
received from Mr. Ellis, 
CLAVARIA BOTRYTES Pers. 
When old the branches both of this species and of C. flava become elon- 
gated, obtuse, very fragile and of a uniform color. The yellow tips of the 
latter and the red ones of the former species wholly disappear. 
Myrorgecium Funeicora Pk. 
This species has recently been referred to WM. inwndatum Tode. The 
spores in that species are represented in Sturm’s Dutchland Flora as globose. 
In our plant they are oblong or cylindrical, a difference which seems to me to 
be of specific value.
