Abstract
A new combination is proposed for plants previously referred to as Spe rmothamnion speluncarum (Collins & Herv.) M.Howe [= Rhodochorton spelu ncarum Collins & Herv.] (Ceramiaceae, Rhodophyta). This red algal spec ies is transferred to Ptilothamnion on the basis of the following char acteristics: the presence of three periaxial cells cut off by the fert ile female axis; a hypogenous cell that is longer than the subapical c ell; and the fact that the hypogenous cell cuts off opposite involucra l filaments. Ptilothamnion speluncarum is reported from Puerto Rico fo r the first time.
