مطالعه گونه های ورتیسیلیوم قارچزی در سواحل جنوبی دریای خزر (استان گلستان، مازندران و گیلان)

During 2003-05 Iranian Provinces in the Southern Caspian coast (Gilan, Mazandaran and Golestan) were investigated in order to collect and identify fungicolous species on various fungal hosts. Isolation was mainly achieved using a binocular and a heat sterilized glass needle. In order to isolate fungicolous fungi PDA and MA each with 100 ppm of penicillin and streptomycin were used. Impure cultured were purified using single spore method. Fifty six isolated were obtained and these were identified using PDA, MA, PCA, CMA and SNA. These isolates were classified into seven genera, Acremonium, Cladobotryum, Fusarium, Sepedonium, Hypomyces, Lecani-cillium, Simplicillium and Trichoderma. Sepedonium and Simplicillium are new records for Iranian mycoflora. Among 13 species obtained, Acremonium cf. recifei, Cladobotryum purpureum, C. mycophilum, Sepedonium microspermum, Simplicillium lanosoniveum, S. wallacei and Hypomyces polyporinus (Cladobotryum vlavisporum) are new records for Iran. A few isolates belonging to Acremonium, Fusarium, Sepedonium and Trichoderma (Table 1) could not be identified to species level with the available methods and literature. Trichoderma was the most frequently isolated genus.
