Relationship between fossil Dictyophyllum (fern leaves) and spores Dictyophyllidites . Dictyophyllum is of the Phlebopteris – type, a fossil fern from the family cf. Matoniaceae ( Traverse 2008) , Dipteridaceae family after Němejc (1963), now containing only Dipteris ( Tryon et Lugardon 1991) ; spores Dictyophyllidites were recorded in situ in the Jurassic fossil fern Dictyophyllum and display a cheiropleuriaceous character (in comparison with recent fern spores); a general survey of the finds and their relationships is given in van Konijnenburg-van Cittert (1989) and Traverse (2008).
