We document 11 of the 21 accepted species in Psilotaceae. The rest are listed, with their authorities and their identifiers, inside their genus. They have no page of their own because we could not find three openly licensed photographs of them, and a page without evidence is not a page we are willing to publish.
| Genus | Documented | Accepted species |

| Tmesipteris | 9 | 18 |
