摘要

Two insufficiently known Middle Devonian columnariid species from the collection ofC. Schlüter are redescribed and figured for the first time.Columnaria devonica Schlüter 1889 is regarded as conspecific withC. sulcata Goldfuss 1826, andSpongophyllum tabulosum Schlüter 1889 has to be treated as valid name for the younger synonymColumnaria cacotropia Glinski 1955.
