Rhizosphere and root surface fungi of some heath plants and the role of Dark Sterile forms

Many different species of fungi have been isolated from the root region of heath plants. In the absence of rapidly growing species,Dark Sterile forms predominated in culture plates. It is suggested that these have an important ecological role in the soil-root interface. AsDS forms do not appear in culture plates easily any floristic list of fungi from the root surface not mentioningDS forms must be accepted with caution. Attention is drawn to the fact that these are truly root-inhabiting fungi possessing some parasitic or mycorrhizal propensities.
