(F,G) Adeonella flabellata: the unique colony consisting of a stalk-like proximal part and distal enlarged blades. Coralligenous bottoms from Mana, 20–40 m. Scale bar: 1 mm for all figures.	Figure 1. Colony morphology of some Adeonella species from the Mediterranean area. (A–C) Adeonella calveti from an overhang, off Acitrezza, about 40 m: basal (A) and top (B) views of the same colony, formed by a set of contiguous fans, each consisting of branches dichotomizing in the same plane. (C) Detail: note how anastomoses are avoided through changes in the growth direction of branches and their tilting and twisting.
