Taxonomic remark ?Not validly published: the type species, H. scissa J. v. Pia, is listed as "invalid Art. 38" in Index Nominum Genericorum. (Article 38 refers to the requirement for an illustration or figure to accompany the description, a reference to a previously and effectively published illustration or figure, for taxa published from 1912 onwards). Original assignment Chaetangiaceae, along with Gymnocodium (latter first described as a green alga); Elliott, 1955 created the new family Gymnocodiaceae for Gymnocodium and some similar genera.
