Summary
Potential growth stimulation of two hosts by acid-tolerantAcaulospora laevis was tested in a soil adjusted to 5 pH levels from 5.0 to 7.7. By wet-sieving methods, the field-source inoculum was essentially a pure culture ofA. laevis spores. Upon harvest of sweetgum a completely different spore-type was found in large quantities;A. laevis spores were relatively few to non-existent. The results dramatically underscore the need for caution against relying solely on pre-trial identifications of inoculum spores or presuming that apparently single-species cultures/inoculum will remain pure throughout an experiment.
