This liverwort was named in 1965 from eastern North America as distinct from the European A. maxima. Older collections in Virginia identified as A. pinguis need to be re-examined for possible additions to the range of A. sharpii. To date, the species has only been identified from a few mountain counties.
Aneura and Pellia are often mistaken for one another and care must be taken to examine papillae just under the thallus margins. Those of Pellia are two-celled (ie. trichomes) with the basal cell often being darkened; the single-celled papillae of Aneura are hyaline throughout.
In 2023, a Chesterfield County specimen at URV collected in 1950 was redetermined to be A. sharpii. The collection locality, "under waterfall in quarry," is in the eastern Piedmont, some seven or eight counties east of the other known Virginia collection sites. This suggests that the species, though obviously very local, could be more widely distributed across the mountains and Piedmont.
Various wetland habitats so far known: shaded spring outflow; wet boulders in mountain stream; wet ground in skunk cabbage seep; under waterfall in quarry.
