The presence of mycorrhizal fungi in the rhizosphere of the shrub Cytisus monspessulanus has been studied in three sites in the province of Tangier, northwest of Morocco: R’milat, Boubana and Sloukia. These sites contain large populations of Cytisus monspessulanus.The number of mycorrhizal spores detected in soils collected in the field was relatively high with 3773 spores/100g of soil. Microscopic examination of Cytisus monspessulanus roots has revealed the presence of vesicular-arbuscular-mycorrhizal (VAM) in all samples. Mycorrhizal frequency (F) found in this study was a maximum percentage of 100%.The highest mycorrhizal intensity (M)was observed at the site of Sloukia with 38.62% ,and arbuscular intensity (A) reached 21% in the same site .But the provisional identification test species of VAM, revealed the presence of six genera: Glomus, Acaulospora, Entrophospora, Paraglomus, Septoglomus, Rhizophagus.
