About Calypogeia muelleriana (Schiffn.) Müll.Frib.
There is doubt about the presence of Calypogeia muelleriana in Algeria. Bischler (2004) stated that it was previously recorded in Algeria, but no published reports under this name have been found. This record might be based on some old reports of C. trichomanis. Bischler (1970) indicated that some African records she revised belong to C. muelleriana, though no precise information was published.
