Article Title

Nomina Excludenda


The following names have been described on the bases of material not included in the families treated above. Most of these names were originally described as members of the Chroococcaceae, Chamaesiphonaceae, or Clastidiaceae; or were transferred into those families at one time or another; or have been suspected as being members of those families. Where the original specimens have not been available for study, we have designated the original description as the temporary Type, to serve until specimens seen by the author can be found.
