The morphogenesis of macromycetes is a complex multilevel process resulting in a set of molecular-genetic, physiological- biochemical, and morphological-ultrastructural changes in the cells. When the xylotrophic basidiomycetes Lentinus edodes, Grifola frondosa, and Ganoderma lucidum were grown on wood waste as the substrate, the ultrastructural morphology of the mycelial hyphal cell walls differed considerably between mycelium and morphostructures. As the macromycetes passed from vegetative to generative development, the expression of the tyr1, tyr2, chi1, chi2, exg1, exg2, and exg3 genes was acti-vated. These genes encode enzymes such as tyrosinase, chi-tinase, and glucanase, which play essential roles in cell wall growth and morphogenesis.
