Collected stocks of Pholiota nameko (T. Ito) S. Ito and Imai confirmed
that the harvests of fruiting bodies were late and had declined. Thes
e changed stocks were subcultured on PDA (potato-dextrose-agar) plate
media, and changes of the cultural properties, nuclear phases and colo
ny types of subcultured stocks were examined. For most of the changed
stocks, the occupied areas of sectors with little aerial hyphae increa
sed with repeated subcultures and finally they occupied whole areas. T
hen dedikaryotization was observed. Only one side, of both nuclear com
ponents of the dikaryon, was observed as a result of a mating type ana
lysis of the monokaryon from dedikaryotization. Monokaryotic mycelium
from dedikaryotization, which constituted a ''flat'' colony, lost the
ability to be a recipient mycelia on PDA plate media, and it grew fast
er than the original dikaryon and normal monokaryon. Most of them lost
their abilities to from fruiting bodies.
