Dataset with phylogentic annotations

I have developed a new clustering technique, and I want to compare my results with those of Mothur and other (k-mer) based clustering techniques. For ground-truth I need to use the phylogenetic annotations in family level (or species level). Similar to this paper http://www.biomedcentral.com/1471-2105/15/321 where they got their data from http://doua.prabi.fr/databases/hogenom/home.php?contents=query

However, I cannot get those datasets. Can anyone point me to a resource of good datasets for clustering application with existing phylogenetic information?

I would appreciate your help,
