Siphonodendron is an extinct genus of colonial rugose corals common during the Carboniferous period. In fossil form it now appears as a white or brown mass of short spaghetti-like threads, usually flattened during distortion of the embedding limestone. It is in the sub-class Hexacorallia of corals with sixfold symmetry.
