Abstract: 

Some 500 isolates belonging to Altemaria species were obtained from seeds and plant parts from various localities of Iran. Prior to morphological examination, pure cultures were obtained by single conidium and single chain methods. Descriptions for each taxon are based on cultures developed on potato carrot agar. Inoculated plates were incubated at 23-25°C under a cool-white fluorescent light/dark cycle of ca. 8/l6 hrs. Microscopic examinations were carried out after 5-7 days and 90% lactic acid was used as mountant. Conidiophores, conidia and sporulation patterns were studied and recorded. Eight species of Altemaria are introduced and described in the present investigation, three of which (A. dauci, A. radicina and A. triticina) are being reported for the first time from Iran. Other five species,A.altemata, A. brassicicola, A.nobilis, A. macrospora and A. ziniae, that have been reported from Iran previously, are described here based on the current species concept.
