Among the edible agarics in Japan, Matsutake (
Armillaria Matsutake S. ITO et IMAI), Shiitake (
Cortinellus Berkeleyamus S. ITO et IMAI=
Cortinellus Shiitake P. HENN.) and Nameko are the most common and highly prized. On the taxonomy of the former two species, the writer with Prof. SEIYA ITO discussed in detail in the previous paper. Now the present short paper was prepared on the last fungus.
Nameko is a common local name, applied to the agarics which have viscid or gelatinous pileus, and in which at least the following, six species are included,
viz. Collybia velutipes, Collybia Nameko, Pholiota adiposa, Pholiota mutabilis, Flammula lubrica and Flammula lenta. After the detailed remarks on the morphological characters of each of these species, a special attention was given to
Collybia Namelco, which was described by Dr. TOKUTARO ITO in 1929.
The writer obtained the fresh materials of the fungus from Hokkaido and Yamagata-Prefecture, which is popularly known as “Nameko” in these districts and also the “Nameko” fungus canned for sale from Fukushima-city. It was proved that they are identical in species, and it belongs to the genus Pholiota. After the careful comparison of our fungus with the description of
Collybia Nameico, it was concluded that they are identical with each other. Naturally, the name
Collybia Nameko should be changed to
Pholiota Namcko (T. ITO) S. ITO et IMAT. The revised diagnosis of the Nameko-fungus in the strict sence was given.
The fungus is easily distinguished from other members of the Truncigeni-section of the genus
Pholiota by the gelatinous nature of the pileus, stem and annulus, and by the smaller spores, obtuse at both ends, as well as by the absence of cysticlia.
