BOLETUS RUBINELLUS.
BY H. C. BEARDSLEE.
Through the courtesy of the British Museum officials, extended
through Mr. Lloyd, I have been able to compare the microscopic
structure of Boletus rubinellus with that of its close relative, the
Knglish Boletus rubinus.
The American species seems to be rather rare. It occurs every
summer at Asheville, where I find it in pine woods in August. It is
one of our most interesting species, and is marked especially by its
small size (the pileus being 2-4 cm. broad), and the unusual color
of the tubes, which are a beautiful carmine in the young plant and
fade to ferruginous as the spores develop. A number of our species
have the mouths of the tubes more or less red, but the tubes are
in which the tubes
yellow within. This is not the case in this species
are of one color, though this changes as has been indicated. One
who has watched it growing would hardly be willing to classify it
with Luridi, as classed by Mr. Murrill, along with B. Frostii and B.
luridus. Personally, I should prefer to place it in Subtomentosi, to
which Smith referred his species. The pileus is slightly viscid at
times, but it should scarcely be placed with Viscidi.
The interesting question in regard to this species is its relationship
to Boletus rubinus. The English species has all the gross characters
of our plant. It has the same small size, same yellow, un-
NOTE. We take the liberty of publishing two Porias, received from Rev. H. Bourdot, with his
figures and description. We do not know that Rev. Bourdot expects us to publish them, but as the
specimens are in our museum, we think it well to legalize the names.
