Popis:	A morphological, anatomical and taxonomic account of Paulsilvella Woelkeriing, Sartoni & Boddi gen. nov. (Corallinales, Rhodophyta) is provided. Paulsilvella belongs to the Corallinaceae, subfamily Lithophylloideae sensu lato (encompassing the Amphiroideae) and differs from other lithophylloid genera (Amphiroa, Ezo, the Lithophyllum-Titanoderma complex, Lithothrix, Tenarea) in possessing nongeniculate protuberant branches that resemble a series of fused beads. The branches are entirely monomerous, with a core region composed of single arching tiers of elongate, columnar cells alternating with two tiers of short, noncolumnar cells. Paulsilvella includes one known extant species, P. huveorum Woelkerling, Sartoni & Boddi sp. nov. from Somalia and Kenya, and one known fossil species, P. antiqua (G.F. Elliott) Woelkerling, Sartoni & Boddi comb. nov. from the Late Pleistocene of Mauritius. The latter was originally described as Lithothrix antiqua (‘antiquum’). In P. huveorum, the uniporate carposporang...
