1900] Webster, — Boleti collected at Alstead, N. H. 175 
Of the viscid Boleti only a few species occur so early in the season. 
Boletus Americanus Peck has been repeatedly collected. Reports of 
it are not infrequently to be referred to Boletinus pictus, which in its 
late stages loses most of its tomentum and appears very yellow. B. 
albus Peck has occurred several times in open woods, and B. granula- 
tus L. more often, though not in its autumnal abundance. One or 
two specimens intermediate between the two, but inclining towards BZ. 
albus suggest the close affinity of the two species. I have generally 
found, however, that in B. albus the pileus is small in comparison 
with the length of the stem. 
The only other members of the section Viscipelles so far found 
about Alstead are B. ruózne/us Peck, and B. piperatus Bull, two species 
which hardly show any viscidity, except in wet weather. The former 
grows in small quantity in two or three localities, one of which is in 
mixed woods, and another on an open hillside in moss just at the edge of 
a hemlock grove ; one or two plants grew on decayed wood. Although 
at first glance much like B. piperatus, especially when the pores have 
become brown, the red and yellow tints of pileus and stem easily dis- 
tinguish B. rudined/us. In its young state its coloring is most attrac- 
tive, the comparatively large pores and often the upper part of the stem 
being of a peculiar red — almost Indian red in one instance. With 
the ripening of the spores this striking tint disappears from the tubes. 
Some dried specimens still retain a trace of it, and preserve the red and 
the marginal yellow of the pileus remarkably well. In the dozen 
or more specimens found, the stem was yellow at the base as in B. piper- 
atus,and with yellow flesh ; it was minutely flocculose above, and fibrous 
striate below. The yellowish white flesh of the pileus generally showed 
a faint band of pink near the pores. The dimensions of the spores 
were 13% by 3% m, ora little more [12% to 15 by 4, Peck]. Mature 
plants were found on July 21, 1899, and somewhat younger ones on 
July 18, 1900. Whether it will continue to appear at about that date 
remains to be seen, but it is not improbable that it may always be fairly 
prompt to date, like some other species, whose limited occurrence both 
in place and time is in such strong contrast with such plants as B. 
scaber, B. subtomentosus, and even B. piperatus. ‘The last species is 
fairly abundant along roadsides and in woods, from the middle of July, 
or earlier, well into August, and probably later. In dried condition its 
resemblance to the browner forms of B. rudinellus is close. The deter- 
mination of B. rubinellus was kindly confirmed by Mr. Peck.
