摘要：

Nitrogen fixation has been demonstrated to occur in the cephalodia of the lichen Peltigera aphthosa which contain a species of Nostoc. The rate of fixation is very high in comparison with the maximum rates for N. muscorum under optimum culture conditions. Virtually all of the nitrogen fixed is secreted to the lichen thallus at a rate equal to the rate of fixation. The possible control mechanisms of this secretion are discussed.
