phytoplankton taxa composition of the caspian sea were evaluated by using samples collected at 12 stations along the iranian coast of the caspian sea between 1996 and 2010. this study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). the dominant species were the ...

Four paddy fields in Guilan province in the north of Iran seasonally were sampled from April 2008 to January 2009. Twenty-two morphospecies belonging to three families of the heterocystous blue-green algae were identified. Fourteen species and one variety of these taxa are new record for Iran. Among the families Nostocaceae with six genera and 16 species showed the highest species richness.

three species of the genus xylaria (xylariaceae) are presented based on collections from guilan province, iran. both morphological and molecular characteristics were used in order to identify these species. xylaria longissima sp. nov. is described and illustrated as a new xylaria species and x. cf. striata and x. xylarioides are reported as new records from iranian mycobiota. xylaria longissima...
