Fungal communities on the dead bark of twelve living tree (Acacia Arabica, Azadirachta indica, Casuarina equisetifolia, Eucalyptus rostrata, Ficus sycomorus, Malus domestica, Mangifera indica, Morus alba, Psidium guajava, Ricinus communis, Salix safsaf and Vitis vinifera) were studied in Nile Delta region. Eighty-seven fungal taxa were identified. Thirty, thirty-nine, and eighteen species were recorded from ascomycetes, anamorphic fungi and myxomycetes, respectively. The most common genera were Chaetomium, Zopfiella, Podospora, Saccobolus and Physarum and the most common species were Zopfiella latipes, Zopfiella karachiensis and Chaetomium bostrychodes. Eucalyptus rostrata, Casuarina equisetifolia and Salix safsaf trees records the highest number records and diversity of fungi.

Seasonality of freshwater ascomycetes was studied in Nile Delta region from February 2010 to December 2011. One hundred and ten ascomycetes were identified through this investigation. The most common ascomycetes recovered during fluctuation study of Delta region were Zopfiella latipes, Microthelia sp. 1, Helicascus aegyptiacus and Naïs aquatica. Physico-chemical analysis (Water temperature, pH, concentration of NH3, NO2and PO4 3-) were recorded and had significant effect during this study.
