Very similar in shape to P. Capitatus, but this variety has a completely flattened top. It is lightly calcified and features a long stem, with fine, soft filaments at the top. These particular plants grow much larger than other species of Penicillus, up to 6" tall. It is abundant on the reef flat and among sea grass beds.  Its root-like structure is a large bulb with a series of rhizoids that anchor it to substrate and sometimes rocks. It occurs in shallow calm protected water, but is also found as deep as 100 ft. In the aquarium the mature plant often dies to produce new plants at its base. Like most calcareous stem plants, it needs a deep sand bed of 4" or more to grow in the aquarium. Calcium supplementation is needed. Not palatable to fish or invertebrates.
