Type.

Remarks.

This taxon is broadly Sino-Himalayan-Taiwan-Japanese endemic, distributed within this large area quite disjunctively (although this may reflect the data deficiency). It was described from Sikkim ( Mitten 1860), later recorded from Taiwan ( Wang et al. 2011) and eastward from southernmost Japan ( Inoue 1969; Yamada and Iwatsuki 2006). A questionable record is from Hawaii under the name Calypogeia waialealeensis   (H.A. Mill. & Kuwah.) H.A. Mill. ( Miller 1967) - the name synonymized with C. aeruginosa   by Inoue (1969). From the geographic point of view, this synonymization should be doubted and the status of the populations from Hawaii should be rechecked, including molecular-genetic methods implementing. We recently found C. aeruginosa   in northern Vietnam ( Buczkowska et al. 2018) which may imply its broader distribution in the Meta-Himalaya. The taxon is very distinctive among congeners due to transversely elliptic underleaves as large as or larger than leaves and may be rather mistaken at the time of collection for Leucolejeunea   due to size, color, leaf orientation and large underleaves (obscuring the fact that the lejeuneaceous lobule is absent here).
