Strikingly preserved in an iron-rich hump on a grey limestone, one of the commonest Mississippian corals in the British Isles, France, Belgium, Germany and Russia. Not known from Asia, Africa, Australia or the Americas.
Frequently found as an erratic on many parts of the British Isles coast.
The simplest and narrowest Siphonodendron species (typically 2.5 - 3.8mm), easy to identify as it has no dissepiments.
Central columella present in most corallites, with dome shaped or conical tabulae.
Usually sixteen major septa. (14-18 possible)
Minor septa may be present.
The calcite filling in the voids is transparent and the specimen is varyingly coloured with presumed haematite, highlighting the structure visible below the surface.
