Chonecoleaceae (Lophocoleineae) is a synonym of Cephaloziellaceae (Cephaloziineae) and Rivulariella (Jungermanniineae) belongs to Scapaniaceae s.l. (Cephaloziineae)

Abstract

Jungermannia doellingeri has alternatively been aligned with Harpanthaceae, Lophocoleaceae, Plagiochilaceae, and Lophoziaceae. Currently it is placed in a monogeneric family Chonecoleaceae of Jungermanniales suborder Lophocoleineae, as Chonecolea doellingeri. Maximum likelihood analyses of a chloroplast DNA rbcL-rps4 dataset of jungermannialean liverworts suggest a position of Chonecolea in Jungermanniales suborder Cephaloziineae and a synonymy of Chonecoleaceae and Cephaloziellaceae. The monospecific genus Rivulariella is not affiliated with Jungermanniaceae but related to Scapaniaceae s.l. (including Anastrophyllaceae and Lophoziaceae).

Cephaloziella konstantinovae (Cephaloziellaceae, Marchantiophyta), A New Leafy Liverwort Species from Russia and Mongolia Identified by Integrative Taxonomy

“…In the present study the narrow concept of Cephaloziellaceae of Schuster (2002) rather than the wide concept of Söderström et al (2016) is accepted; however, we take the proposals of CrandallStotler et al (2009), Gradstein et al (2014) and Patzak et al (2016) Although the present analyses did not resolve deeper nodes of Cephaloziella, it is clear that our new species is nested within this genus.…”

“…According to Schuster (2002), none of the genera of Cephaloziellaceae have this combination of character states of the reproductive structures. In Chonecolea, which is considered an element of Cephaloziellaceae by Patzak et al (2016), all of those characteristics are present, but the spore surface in Chonecolea is reticulate, whereas in Cephaloziella konstantinovae as well as other Cephaloziellaceae (except Cylindrocolea reticulata) the spore surface is finely granulate, papillose or verruculose.…”

New insight into the taxonomy of Cephaloziellaceae (Marchantiophyta): the family of the smallest higher plants on Earth

“…A robust step forward in understanding the phylogenetic relationships of the Cephaloziellaceae was made by Patzak et al. (2016) .…”

Konstantinovia Is Not Monotypic, and a New Attempt to Determine Relationships in Cephaloziellaceae–Scapaniaceae Superclade (Marchantiophyta)

“…Considering unstable topologies and weak nodal support, Váňa et al [ 6 ] proposed a compromise in which Scapaniaceae, Lophoziaceae, and Anastrophyllaceae were interpreted in the narrow senses, while all “transitional” elements (like Obtusifolium , Protolophozia , and Oleolophozia with typical lophozioid appearances) were added to Cephaloziellaceae, turning the latter into a ‘superfamily’. A similar view, with the only difference being that the transitional elements were treated as belonging to the Scapaniaceae (making it a superfamily), was adopted by Patzak [ 7 ].…”
