The mycorrhizal fungi are the beneficial fungi in forest tree nurseries, field forestation, and natural stands. Two primary types of mycorrhizae are the ectomycorrhizae and the endomycorrhizae. The ectomycorrhizae form a rather conspicuous fungus mantle on the surface of the feeder roots primarily on conifers (pine, fir, spruce, hemlock, larch, D-fir) along with some hardwoods (oaks, birch, eucalyptus). The endomycorrhizae develop within the root cortical cells primarily on hardwoods such as walnut, poplar, maple, sweetgum, sycamore, and ash. The ectomycorrhizae also produce a variety of fruiting bodies such as puffballs and mushrooms above ground and their spores are wind-disseminated. However, the endomycorrhizae produce their spores on infected root surfaces below ground and, consequently, are limited to localized distribution in the soil by water, soil tillage, etc. Both types
of mycorrhizae occur on a wide variety of plant hosts throughout the temperate zones of the world and their occurrence constitutes the rule rather than the exception in nature.
