Abstract

Riccia anguillarum Cargill, is described from Western Australia. This endemic species is distinguished by a fleshy, succulent thallus (similar to southern African species of Riccia in section Spongodes, group ‘Vesiculosa’). It is also unique within Riccia and the Ricciaceae in having a thallus of multilayered air spaces and a bi-layered capsule wall. A description of the new species with images, illustrations and map of its locations is provided.
