This type of mycorrhiza resembles the ectomycorrhizas formed with forest trees but differs from them because of the cell penetration. The fungi involved are Basidiomycetes and mainly species that form ectomycorrhizas with forest trees. The presence of the fungal sheath, as in ectomycorrhizas, insulates the host from the soil. Hence all minerals absorbed by mycorrhizal roots must pass through this sheath. All rights reserved.
