Fig. 72. (Top) A stand of K. cylindracea in the lagoon of Enewetak Atoll, photographed 

 from above. Clumped and linear arrangements of thalli suggest clonal development. 

 Long dimension of large clump in lower left-hand corner is approximately 9 cm. 

 (Bottom) Clonal development in stuposa, at the northern end of the lagoon of 

 Enewetak Atoll. Excavation indicated that many of the stuposa clones were the 

 result of lower portions of the thalli being buried in shifting sand. Note the different 

 ages of thalli, the clumped or sometimes linear arrangement, and the overgrowth 

 of some thalli by blue-green algae. Approximate width of the cjdindrical segments 

 is 2 mm.
