Hartig net structure and ontogeny were compared in ectomycorrhizae synthesized between the broad host range fungus, Laccaria bicolor and two hosts, Betula alleghaniensis and Pinus resinosa. In B alleghaniensis, the Hartig net was present in the epidermis of the three ectomycorrhizal types formed, fast-growing first-order laterals with proximal colonization, clavate second-order laterals, and nonclavate second-order laterals. Root hair-fungus interactions occurred in this association. In P. resinosa, the Hartig net developed in epidermal and cortical cell layers of monopodial and dichotomously branched first-order laterals. Short monopodial laterals exhibited a mantle only. Fungal hyphae in the Hartig net exhibited a complex labyrinthine mode of growth in ectomycorrhizae of both tree species.
