WAERNIA MIRABILIS GEN. NOV., SP. NOV. (DUMONTIACEAE, GIGARTINALES): A NEW NONCORALLINE CRUSTOSE RED ALGA FROM THE NORTHWESTERN ATLANTIC OCEAN AND ITS RELATIONSHIP TO GAINIA AND BLINKSIA 1
Waernia mirabilis Wilce, Maggs et Sears, gen. et sp. nov., is described for an encrusting red alga endemic to the northeastern North Atlantic Ocean. Its perennial thalli form major understory populations that may outcompete Corallinaceae and Hildenbrandiaceae in some habitats. Crustose red algae wit...
