Leaves of two wild species of the flora of Egypt: Calotropis procera ( Ait.) Ait., Asclepiadaceae and Chrozophora plicata ( Vahl) A.Juss . ex Spreng ., Euphorbiaceae have been studied morphologically and mycologically, in addtion to air borne fungi. Fifty five species and two varieties belonging to 26 genera of phyllosphere and phylloplane fungi were isolated from both plant species on glucose‐ and cellulose‐agar media. Mycological analysis was done monthly over six months (July to December, 2003). Alternaria alternata, Aspergillus fumigatus, A. flavus and A. niger were the basic fungal species found on leaf surfaces. Phylloplane of C. plicata caught specifically Chaetomium globosum, C. spirale, Cochliobolus lunatus, Drechslera halodes, Fusarium incarnatum , F. oxysporum, Memnoniella echinata and Papulaspora sepedonioides . The total counts of phyllosphere fungi of C. plicata were nearly twice as much as those of C. procera regardless medium's type. Forty species and one variety belonging to 22 genera of air borne fungi were recovered all over the experimental period (six months). Alternaria, Aspergillus , Cladosporium and Penicillium were the most frequently isolated species. The presented results revealed that, leaf shape and density (hair density and type) may be the most important factors of the biodiversity of the fungal species on the studied taxa.
