HOKKAIDO. I

Introduction
The most important scientific report of the Japanese Agaricaceae
was published early in 1860 by M. J. BERKELEY and M. A. CURTIS
under the title of "Characters of New Fungi, collected in North Pacific
Exploring Expedition by Charles Wright", in the Proceedings of the
American Academy of Arts and Sciences, Vol. IV, pp. 110-130. In
this paper 64 species of the Agaricaceae of Japan were first described.
Thereafter some fragmental studies of our agarics have been reported
by J. SCHROETER, N. TANAKA, P. HENNINGS, P. HARlOT, N.
PATOUILLARD, S. KAWAMURA and others.
As for the Agaricaceae of Hokkaido no conclusive report has
been published up to the present time. BERKELEY and CURTIS, however,
described two new species, Agaricus (Collybia) adianticeps and
Agaricw; (Galera) japonicw;, collected in Hakodate, in their paper
mentioned above, and the present writer dealt with several agarics
collected from various localities in Hokkaido in his papers ever
published.
The present studies were first undertaken in 1924 to dwell consistently
upon the Agaricaceae of Hokkaido, under the directibn
of Prof. KINGO MIYABE, and then after his retirement, continued
under the direction of Prof. SEIYA ITO.
The materials examined in this study were chiefly collected by
the writer himself, supplemented partly by colleagues in our Institute
and by other gentlemen in our district.
The specimens examined are preserved in the Herbarium of
the Botanical Institute, Faculty of Agriculture, Hokkaido Imperial
University.
