Abstract: The mycota colonizing the ectorhizo-sphere-rhizoplane zone of Avicennia marina, Haloc-nemum strobilecium,Z ygophylluma lbum, Z. coccineum, Z. simplex, Arthrocnemum macrostachum and Limon-astrumm onopetalumw ere investigateda long the Red Sea Coast of Egypt.C zapek-Dox basal medium in sea-waterw ith differentc arbon sources (glucose, xylan, starch, cellulose and tannin) in replacement of su-crose, was used as isolation medium. A total of 41 microfungals pecies belonging to mitosporicf ungi (36 spp.), Zygomycota( 3 spp.) and Ascomycota( 2 spp.) were isolated. The most common species were Cladosporium cladosporoides, Penicillium chrysogenum and Aspergillust erreusv ar. aureus. Higher counts were observed on xylan,s tarcha nd cellulose,l owerc ounts on tannin.T he rhizospherec ontainsb oth xerotoler-ant and nontolerant species. Scolecobasidium arenar-ium was the only recorded arenicolous marine spe-cies. Detrended correspondence analysis separates the isolated species into ten communities,e ach one is specific for a particular plant. Canonical corre-spondence analysisb iplot shows that the patternso f species abundance in the rhizospherew as influenced by changes in organic content, total nitrogen, pH and total dissolveds altsi n surroundings oil.
