SUMMARY

Small, more or less spherical metachromatic granules have been detected within the Hartig net and inner sheath hyphae of Eucalyptus fastigata mycorrhizas, and shown by various cytochemical tests to contain polyphosphates. These granules are believed to be the cytological equivalent of the biochemically characterized phosphate storage pool which other workers have defined on the basis of radiotracer studies.
