The boletes of Michigan, by Alexander H. Smith and Harry D. Thiers.

DEDICATION
THIS work is dedicated to Victor Clare Potter, of Ithaca,
Michigan; born May 14, 1920, died January 11, 1964.
Victor Potter was a victim of arthritis, but this did not
dampen his enthusiasm for natural history. He had special
crutches made so that he could carry a collecting basket on
one of them, and, so equipped, he made, in the short period
of less than fifteen years, a collection of fleshy fungi of
approximately 20,000 specimens, which is the most significant collection in existence from the central part of the
Lower Peninsula. Many of them were boletes, including one
of the most peculiar species of Leccinum yet described,
which now bears his name.
He clearly showed by his own efforts that the amateur
naturalist can still make significant contributions to biology.
Indeed, the project on the boletes of Michigan has profited
significantly from the activities of a number of amateurs in
the state.
