Penicillus
Penicillus is a genus of calcified, siphonous green algae in the order Bryopsidales. Members of the genus are commonly called shaving-brush algae because of their upright stalk and brush-like head. Current marine taxonomic databases place Penicillus in the family Halimedaceae, tribe Udoteeae, although the genus has also been treated in Udoteaceae.
