| Epigraptus Eisenack, 1941 Synonym: Idiotubus Kozlowski, 1949 |
Diagnosis (by P. Mierzejewski, 1978):
"The erect portions of autothecae arranged in rows and arise directly from the surface of
thecorhiza. The autothecal apertural apparatuses are in the form of a single or two
lamelliform or bifurcate processes. The bithecae are restricted to the thecorhiza".
