The alga, Powysia bassettii gen. et sp. nov., is described from the early Ludlow Series at Llangammarch Wells, Powys, mid Wales. The most complete specimen consists of a thallus differentiated into holdfast, stipe, and much branched distal region, all of which appear to have a tubular construction. Reproductive structures have not been found. Comparison is made with living and fossil algae, but the precise affinities of these Welsh fossils, in which a thallus of such marked morphological differentiation has an apparently simple internal structure, remain unresolved.
