The resurrection of Neohattoria Kamim. (Jubulaceae, Marchantiophyta): a six decade systematic conflict resolved through a molecular perspective

Abstract

The systematic placement of Frullania herzogii has been contentious since its description six decades ago. Over the years it has been interpreted as either a member of the genus Frullania or segregated into its own genus, Neohattoria, due to morphological similarities with both Frullania and Jubula. Here we provide molecular evidence that supports the recognition of the genus Neohattoria and its inclusion within the Jubulaceae, together with Jubula and Nipponolejeunea. Jubulaceae are placed sister to Lejeuneaceae rather than to the monogeneric Frullaniaceae.

Hepatics from Rovno amber (Ukraine). 12. Jubula polessica sp. nov.

“…In this classification the genera Amphijubula, Neohattoria, Schusterella, and Steerea are considered to be synonymous with Frullania. A later molecular phylogenetic study of the Jubulineae by Larraín et al (2015), however, demonstrated Frullania herzogii S.Hatt. (≡Neohattoria herzogii) to have a sister position within the Jubulaceae with Nipponolejeunea S.Hatt., thus reinstating the genus Neohattoria.…”

“…The joining of Amphijubula, Schusterella and Steerea within Frullania enabled a rather straightforward assignment of extant species having the relevant morphology to one of the two lineages -Frullaniaceae or Jubulaceae -based on the distinctions listed in Larraín et al (2015). These include:…”

“…Until now, indirect indications on the possible Paleogene origin of this genus were the records of the Eocene species of the genus Nipponolejeunea coupled with the molecular phylogenies showing a sister relationship between Nipponolejeunea and Jubula (e.g. Ahonen 2004;Forrest et al 2006;Heinrichs et al 2005Heinrichs et al , 2007Larraín et al 2015). In Heinrichs et al (2018: Fig.…”

“…Nomenclature of initial branching appendages follow von Konrat & Braggins (2001). For the production of microscopic images we used the same set up and protocols as described in Larraín et al (2015).…”

Three’s a crowd: a revision of the monotypic family Goebeliellaceae (Porellales: Jungermanniopsida).

“…Of the seven families, four have diversity in the hundreds of species, the Lejeuneaceae in particular probably comprises in excess of 1000 species, and the other three families have diversity lower by orders of magnitude. The Jubulaceae has four species in two genera (Patch et al 2010;Larraín et al 2015), the Lepidolaenaceae around 20 species in three genera, and the Goebeliellaceae a single species, Goebeliella cornigera (Mitt.)
