Abstract
Audouinella chalybea (Roth) Bory has been recorded from Phamrong falls of Sikkim Himalaya. Well developed plants of the alga were found attached to the stones and pebbles in the running outlets of the falls. The plants were found anchored to the substratum by spine like base attachment cells. Such structure has not been recorded in earlier studies. Both monosporangia and tetrasporangia have been recorded in our plants. This is the first report of the species from eastern Himalaya and appears to be the second report from India.
