110 THIRTY-EIGHTH REPORT ON THE STATE MUSEUM. 
Trocia crispa, Pr. v. VARIEGATA. 
Pileus and lamelle variegated with bluish or greenish-blue stains. 
Sandlake. Sept.: 
Bo.Letus viscosus, Frost. 
This name is antedated by B. viscosus Ventur., and if the Frostian 
species is a good one, it will be necessary to give it another name. 
It cannot be called Bb. Frostii, as there is already a species bearing 
that designation. Mr. Frost’s plant is manifestly very near B. granuw- 
latus and may possibly be a variety of that species, although the 
two, as they occur with us, are readily distinguishable. They ap- 
pear to have been united by European mycologists. The distinguishing 
characters are found in the color, glutinosity, glandular dots or sugary 
granules of the tubes and stem and in the comparative length of 
the stem. In Frost’s plant the pileus is at first dark-chestnut color 
and covered with a thick tough gluten, appearing, as the author 
remarks, as if it “was enveloped in slime,’’ but it becomes yellowish, 
tawny-yellow or reddish-yellow and less glutinous with age. ‘The 
glandular dots are usually entirely absent from the mouths of the 
tubes and from the stem, but when present they are very minute and 
inconspicuous and occur chiefly at the top of the stem. This is very 
short, varying from one-half to one inch in length, so that “ the pileus 
seems to rest upon the ground.” In BS. granulatus, the young pileus is 
much paler, though variable in color, and is less glutinous. It does not 
become conspicuously paler with age and the glandular dots or granu- 
lations, which suggest the name of the species, are readily seen on the 
tube mouths and stem. ‘They usually dot the stem from top to base, 
though sometimes they are more conspicuous on the upper part. The stem 
is generally one to two inches long. This plant appears from midsum- 
mer to the end of the season, but I have only seen Frost’s plant in late 
autumn. It is quite possible that the two plants run together, but from 
the character of the differences noted it seems tome to be best at 
present to keep them distinct, and for convenience of reference I would 
designate the Frostian species as Boletus brevipes, in allusion to its 
short stem. It grows in sandy soil under pine trees. Karner. Oct. 
BOLETUS SCABER, J. v. NIVEUS. 
Swamps. Karner. Oct. This is a beautiful variety, easily recognized 
by the white color of the pileus, This, however, becomes tinged with 
livid-blue or greenish-blue when old. 
BoLETUS GRACILIS, Pk. v. LAVIPES. 
Stem destitute of reticulations. Otherwise like the tpyical form of 
the species. South Ballston. Sept. 
POLYPORUS SULPHUREUS, J”. 
The young growing plant sometimes exudes a pale-yellow or sulphur- 
colored juice when cut or, broken. 
Potyporus vo.tvatus, Pk. 
This is occasionally found on balsam trunks, Abies balsamea, Adiron- 
dack mountains. June.
