Colonies are dendroid (Fig. 90) with narrow (0-72-1-17 mm), vinculariiform branches which bifurcate infrequently (internode length 1-4 mm to more than 8 0 mm) and are often slightly sinuous. Branches may anastomose and the resultant concave attachment scars are commonly found in fragmented material. Growth tips have a rounded conical shape (Fig. 85A) and are sometimes occluded. Colony bases may be extensive, giving rise to more than one erect branch. Overgrowths (Figs 87-88) ar
