Pseudo-Hippocrates is a later heading for Greek books that travel under the name of Hippocrates of Cos. The ἱατρός of Cos is not identified as the writer of the titles on this page.
What this site holds here is not the Hippocratic Corpus filed under Hippocrates, but a smaller set of treatises and letters later copies attach to him. Titles already on this page: Letter to King Ptolemy—the Fabric of Man, On the Difference of Foods to Ptolemy, On Foods, Interpretation of Active Stones, Letter to King Ptolemy, and On Seven-Month Birth. Several address a King Ptolemy. The letters belong to the Hippocratic letter stream.
These books survive in the Greek manuscript tradition under his name. A treatise here is a Greek book under a later heading, not his signature.
