Delimitation of Cephaloziellaceae

A number of genera traditionally included in Scapaniaceae Migula (1904: 479) , Lophoziaceae Cavers (1910: 293) , or recently Anastrophyllaceae Söderström et al. (2010: 48) , are shown not to be related to those families, but rather to an unresolved region including Cephaloziellaceae . Molecular studies are few and in most cases the taxa shown to belong here have been used as parts of more general studies, as outgroups or believed to be members of the family of interest. The only molecular study dedicated to this group including a fair number of taxa is Feldberg et al. (2013), but as it is a study of divergence time and does not include confidence values, it is difficult to draw too many conclusions from it.

Davis (2004) placed Herzogobryum far outside Gymnomitriaceae Klinggräff (1858: 16) in an unresolved relation within Cephaloziineae Schljakov (1972: 503). He-Nygrén et. al. (2004) and He & Glenny (2010) indicated that Chaetophyllopsis may belong here. De Roo et al. (2007) demonstrated that Gymnocoleopsis is closely related to Cephaloziella and placed Oleolophozia , Obtusifolium, Lophonardia and Gottschelia on long branches basal to Cephaloziellaceae , but not within Lophoziaceae or Anastrophyllaceae . Vilnet et al. (2010) placed Obtusifolium and Protolophozia elongata ( Stephani 1902: 41) Schljakov (1979: 204) here although their position was not stable across their trees. Recent investigation of abundant material of Anastrophyllopsis involutifolia ( Gottsche et al. 1844: 81) Váňa & L.Söderstr. in Váňa et al. (2013: 15) by one of us (JV) shows that it is morphologically very similar to Gottschelia . That genus should thus also be referred to the “ Cephaloziellaceae ” region.

As circumscribed here, Cephaloziellaceae is morphologically heterogeneous and is probably best treated as a ‘superfamily’. Morphologically it is difficult to defend such a diverse family and it should probably be separated into further families. However, this requires more molecular and morphological study. Genera preceded by a * in the following list do not belong to the core Cephaloziellaceae .
