Current status. Invalid.
Remarks. Type material of Sphaerocystis heteronema Fraser, 1943a is known to exist only at the MCZ (MCZ- IZ 9002). No type of the species was designated by Fraser (1943a), but his description was based on a single colony, constituting the holotype by monotypy. That specimen is now dry, accompanied by a note stating “found dry (prior to 1983)”. Nevertheless, three fragments of a single hydrocaulus, and several detached hydrocladia, were found in the vial. Although desiccated, and constituting a very small colony of a particularly large species, its morphology is still apparent and its identity quite certain. As noted above in remarks on the genus Sphaerocystis Fraser, 1943a , S. heteronema Fraser, 1943a is a junior subjective synonym of Plumularia dendritica Nutting, 1900 , a species now frequently assigned to the genus Dentitheca Stechow, 1920 . In common with S. heteronema , the type locality of D. dendritica is the Bahamas (near Little Cat Island).
