Description
Growth form laminar, spheroidal, domed, or irregular, with surface marked by mamelons, predominant are well-defined continuous lamellae, more or less wavy and separated from one another in different specimens or parts of the same colony, or partly lenticular; pillars mosdy short and straight, bifurcate at top or expanded at one or both extremities, restricted to a single interlamellar space; some pillars long and crooked, unbranched or branched to anastomosing, not restricted to a single interlamellar space; these two types may alternate zonally. Astrorhizae large, in vertical systems with branches abrupdy terminated in interlamellar spaces. Lamellae in tangential sections show well-marked reticulate or meandriform structures. Skeletal elements compact, microcrystalline, or granular; a dark or clear filiform axis may be recognized in lamellae and rarely in pillars (6). [This genus is closely allied to forms of Clathrodictyon having well-differentiated skeletal elements; it is distinguished by pardy disordered, branched or anastomosed pillars extending through 2 or more lamellae. So-called zooidal tubes noted by some authors, which rarely occur in sections, seemingly are parts of astrorhizae]
