On small White Pine branch. Distinctive small green thallus. Medulla fleeting KC+ purple. Polysporous asci, thousands of simple hyaline spores. Can't tell if hymenium is inspersed with oil because there were so many spores.

There are numerous marginal soralia and no apothecia were seen. K negative on several attempts. Lobes about 1-2 mm wide. The lower surface is pale with numerous dark rhizines.

It struck me as smaller, and strictly adnate as compared with Porella platyphylla.
On a north-facing vertical bedrock exposure above a woodland stream.
The leaves are half the size (0.5 mm) of Porella platyphylla (1.0 mm).

On a rock cascade of a seasonal stream. Even at this moist time of year, the water did not flower over this moss. Such an event must be infrequent at best, which surprises me very much, as I am accustomed to seeing Fontinalis in situations where it is submerged and must be so for much of the time, given the locations in which it has been found.

Endemic to the Appalachians and one of the only aquatic lichens, this species is uncommon and is indicative of high water quality. It looks like it belongs in a tidal pool. A Pennsylvania 'Watchlist' species.
