Scanning Electron Microscopic Studies of Corticium Rolfsii Sclerotia Parasitized by Aspergillus Terreus

SUMMARY

Parasitism of Corticium rolfsii by a species of Aspergillus was investigated by scanning electron microscopy. Within a few da after A. terreus infected sclerotia of C. rolfsii, conidiophores bearing numerous conidia of A. terreus covered the entire surfaces of the sclerotia. Most conidiophores arose from below the surface of sclerotia, while a few of them originated from the innermost layers of cortical tissue. Microdissection revealed that sclerotial surfaces in contact with A. terreus conidiophores were flat.
