Abstract: 3 tables. 3 figures. ["Forty-four species of New Zealand lichens, including 22 species of Pseudocyphellaria and seven of Sticta, were analysed for nitrogenase activity by acetylene reduction. Nitrogen fixation was confirmed by 15N enrichment studies." All species with blue-green phycobionts showed positive activity, and nitrogen fixation rates were species specific.]
