Sporochnus dotyi sp. nov. (Sporochnales, Phaeophyta), a Brown Alga from Hawaii

Abstract

Sporo chnus dotyi sp. nov. is described based on two collections made in Hawaii. It differs from other Sporochnus species in having nonbranched fertile filaments and in the comparatively large size and conspicuous nature of the bases of the apical tufts. A key to the world's species of Sporochnus is presented to elucidate the unique features of this new species.
