Adeylithon bosencei gen. et sp. nov. (Corallinales, Rhodophyta): a new reef‐building genus with anatomical affinities with the fossil Aethesolithon

Adeylithon gen. nov. with one species, A. bosencei sp. nov., belonging to the subfamily Hydrolithoideae is described from Pacific coral reefs based on psb A sequences and morpho‐anatomy. In contrast with Hydrolithon , A. bosencei showed layers of large polygonal “cells,” which resulted from extensive lateral fusions of perithallial cells, interspersed among layers of vegetative cells. This anatomical feature is shared with the fossil...
