Description
Typically laminar but may be globular or massive, with skeletal elements poorly differentiated to distinct, pillars restricted to interlamellar spaces, but closely associated with lamellae, which are the predominant structures; interlamellary septa may be abundant. Astrorhizae present or absent (22). As currently defined, this genus contains groups showing 2 sorts of structures: forms like the type species, with vesicular or subvesicular tissue lacking clear differentiation of pillars and lamellae (Fig. 97); and forms having well-defined lamellae and interlamellar pillars which may be bifurcate or hollow cone-shaped (Fig. 105,2). Some authors hold that one form merges with the other through progressive straightening of lamellae and separation of pillars, but the second group possibly is generically distinct
