A new reproductive organ is described from tuff deposits within the Pennsylvanian (Bolsovian) age Radnice Member of the Kladno Formation at the Doubrava locality in the Pilsen Basin of the Czech Republic, Sporangia possess four different types of cells and three specialised trichomes. The specialised trichomes in E. libertite appear to have contributed to sporangial dehiscence, and the opening mechanism may have been facilitated by faunal-interaction.

Nové reprodukční orgány jsou popsány z tufových hornin pensylvánu (spodní bolsov) radnických vrstev Kladenského souvrství z lokality Doubrava z plzeňské pánve České republiky. Sporangia mají čtyři typy buněk a tři specializované trichomy. Tyto trichomy pravděpodobně sloužily k otevírání sporangií k čemuž mohlo docházet za pomoci ostatních živočichů.
