Abstract: Ways nutrient-uptake of sclerotia of Grifola umbellata and the relationship between G. umbellata and Armillaria mellea were studied. At the primary stage of sclerotia of G. umbellate infected by A. mellea, the hyphae of G. umbellata could obtain nutrients by invading the one- to three-layer-cells of A. mellea cortex which existed in the sclerotia of G. umbellata, ar late stage of A. mellea infection, the nutrient source of sclerotia of G. umbellata mainly depended on its hyphae, adhering on the intercellular space of A. mellea, to suck the metabolic products of A. mellea. After being nourished the hyphae of sclerotia of G. umbellata outside of the rhizomorph of A. mellea began to reproduce, as their nuclear divisions were well observed. The results suggested that the mutual assimilation between G. umbellata and A. meIlea could be defined as a form of special Symbiotic relation.
