THE STRUCTURE OF DRY MYCELIA OF THE ENTOMOPHTHORALEAN FUNGI ZOOPHTHORA-RADICANS AND ERYNIA-NEOAPHIDIS FOLLOWING DIFFERENT PREPARATORY TREATMENTS

Dried mycelium preparations of the entomophthoralean fungi Zoophthora radicans and Erynia neoaphidis survived several weeks at 4-degrees-C b ut were largely destroyed by freezing or milling. SEM and fluorescence microscopy showed that mucilage was secreted by the mycelium during d rying and rehydration. This mucilage probably helped protect the dried preparations.
