​Lepidodendron (Silesiodendron) shustai Pavela, 2022

​- leaf cushions of significantly smaller sizes

- leaf cushions are more interconnected - more reminiscent of the genus Sigillaria

- less pronounced to missing central keel on leaf cushions

- much denser transverse wrinkling of the leaf cushions

- significantly younger species - occurs in the upper part of the Ostrava Formation
