Annot. by Nils Lundqvist (Uppsala 1967): "Hypocopra gigaspora (Ellis & Everh.) Griffiths = Hypocopra kansensis Ellis & Everh." . . . Annot. by J. C. Krug (Toronto, Sep 1969): "This is identical with H. gigaspora (Ellis & Everh.) Griffiths. Since the latter is a later homonym of H. gigaspora (Fuckel) Sacc., it is not valid even though it was published prior to H. kansensis; the latter must then be considered to have priority, an opinion now shared by Dr. Lundqvist."
