This survey was designed to study the diversity and occurrence of rhizosphere and rhizoplane
fungi in the protectorate of Assiut in Egypt, followed by testing the ability of the most common
isolated fungal strains to produce mycotoxins. Not many mycological studies have been carried
out to describe the fungal fl ora of this area, which will be of great signifi cance for the endemic
mycobiota. Rhizosphere and rhizoplane samples were collected from the protectorate of Assiut,
which represents one of the largest distinctive regions of newly reclaimed soil at the Assiut
Governorate. The identifi cation of the isolated fungi during our investigation was carried out
using the morphological and microscopic features according to many references and confi rmed
by the Assiut University Mycology Center ( AUMC). The most common four fungal species
were examined for their capability to produce mycotoxins; in addition, chemical confi rmatory
tests for mycotoxins were examined.
