Development of mycorrhizae was found to be promoted by inoculating nursery soil with humus and top soil from well-established coniferous plantations, or by application of phosphorus fertilizer. Two types of host cell fungus relationships have been observed. In one type the root has a mantle of mycelium with abundant clamp connections. The internal mycelium is intercellular and segmented into short, straight-sided cells. The second type has a mantle of much coarser, "monilioid" mycelium.
