HYPHOMYCETOUS FUNGAL COMMUNITY OF BARLEY PHYLLOPLANE IN EAST AZARBAIJAN PROVINCE WITH EMPHASIS ON NEW TAXA FOR IRANIAN FUNGAL FLORA

During 2002-03 forty-four different barley growing regions in East Azarbaijan province of Iran were sampled for epiphytic fungi. Isolation of fungi was achieved using standard methods. As the result 374 hyphomycetous isolates were obtained that were placed in 22 genera and 49 species based on colony morphology and microscopic features (Table 1). Among these, Acremonium egyptiacum, A. sclerotigenum, Acremonium sp., Arthrinium arundinis, Art. phaeospermum, Art. sp., Cladosporium malorum, Cladosporium. sp., Penicillium frequentans, Periconia igniaria, Scytalidium dimidiatum and Stachybotrys sp. were new taxa for Iranian fungal flora. Furthermore, the important and pathogenic species, Drechslera teres, is isolated from East Azarbaijan province for the first time. The majority of fungal species obtained in this survey belonged to various species of hyphomycetous genera such as Alternaria, Aspergillus, Drechslera, Fusarium and Penicillium.
