Logs of beech, birch, willow, maples and/or
oaks are given multiple cuts into which sawdust spawn or slices of fresh sclerotia are
packed. The logs are re-buried underneath a
layer of sandy soil and covered with rich humus and deciduous leaves. After three years,
the trenched logs are unburied and new sclerotia can be harvested. For sclerotia harvest, late
spring is best. Fruitbodies are generated from
the sclerotia in the late summer to early fall,
when the ground temperature hovers between
50-60° F. (10-15° C.). For more information,
consult Fungi Sinica, 1980. (See Figure 343.)
