Summary This study was concerned with properties of mycelia-agglutinated terminal root clusters, or mycoplasts,' of naturally reproduced seedlings ofPinus resinosa andPinus strobus. These rhizospheric root appendages, formed at the expense of the host plant's carbohydrates, exhibited high catalytic potential, cation exchange capacity, and content of exchangeable bases, including complexible cations. These attributes suggest that mycelial clusters are important components of tree-fungus symbiotic mechanism that increase availability of nutrients to the trees. The mycelial clusters apparently perform the function of mycorrhizal short roots which are often nonexistent under the conditions of reduced radiation in well-stocked forest stands.
