Neotrichocoleaceae is a family of liverworts in order Jungermanniales. It is closely related to the genera Ptilidium and Herzogianthus.

Phylogeny

Leafy II (2600 spp) Ptilidium Neotrichocoleaceae Neotrichocolea Trichocoleopsis Leafy I (1800 spp) Pleurozia Metzgeriales

The diagram at left summarizes a portion of a 2006 cladistic analysis of liverworts based upon three chloroplast genes, one nuclear gene, and one mitochondrial gene.^[2][3] The genus Trichocoleopsis was not included in the original broad analysis, but it is the sister taxon of Neotrichocolea according to a more narrowly focussed study utilizing six chloroplast genes, two nuclear genes, and a mitochondrial gene.^[4]

The genus Ptilidium is sister to the Trichocoleopsis-Neotrichocolea clade. The genus Herzogianthus is also believed to be related to this group,^[5] although it was not included in either molecular analysis. This combined clade, in turn, attaches at the base of a large clade (2600 species) designated "Leafy II". That clade, together with "Leafy I" (another 1800 species) and Pleurozia constitute the Jungermanniales, as traditionally defined.
