Classification
Description
Massive, meandroid corallum, straight closed valleys without lamellar linkage. Tectiform collines without ambulacrum. Incomplete synapticulotheca. Radial elements are compact or subcompact, curved, often anastomosed (contratingent or by inner edges), probably pennular. Synapticules present, more numerous close to the wall. Styliform columella very often surrounded by small detached trabecules of major septa. Endotheca present.
Comparisons
Like Microphyllia, but differing by the columella and the closed valleys. Like Comophyllia but differing by the mode of increase and arrangement of valleys.
Remarks
to establish the taxonomic validity and the independence of Axophyllia and Microphyllia needs a population approach.
