Hostinella is a form genus, used for bare dichotomously branching stems (axes) which have not been found in association with spore-forming organs or sporangia and so cannot be assigned to a more precise genus or species.[1] Specimens assigned to this genus have been found in Bathurst Island, Canada, in the Bertie Formation of Upper Silurian age (around Шаблон:Period span/brief), where the stems are approximately 1.2 mm in diameter;[2] and in Lower Devonian Senni beds (from around Шаблон:Period span/brief) where the axes have a straited external appearance and contain xylem with tracheids (diameter: 40 µm).[1]

It is known to co-occur with Krithodeophyton.[1]
