Very similar in shape to P. Capitatus, this variety is more heavily calcified and features a short stem, with coarse bristle-like filaments. These particular plants grow much larger than other species of Penicillus, up to 8" tall. Also characteristic of this calcareous algae is that the top is more tapered and flat. It is abundant on the reef flat and among sea grass beds.  It's 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 to depths of 40 ft. In the aquarium the mature plant often dies to produce new plants at it's 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.
