Leafy liverwort on edge of fenny margin along drainage in subalpine
Very abundant mats along stream margin to the lake. Using Judy Godfrey’s thesis key I got to J. hattoriana but idk. No underleaves, trigones or discernible odour. Large shoots, often with flagellate branching, clear to reddish rhizoids, sometimes emarginate leaf apices, 2-5 variable oil-bodies/cell, nice colouration…
@dbltucker @bradenjudson @steveansell -- prolate ribbony fern gametophyte or low energy pellia? On deeply shaded soil of tip up. No sample, Maybe not fern-- midrib seemingly present. But so thin.
Hybrid Polystichum setigerum X Polystichum lonchitis ?
On south facing side of presumably siliceous boulder used as trail marker. First two photos are from February. Was extremely difficult to take a sample, as plants were tiny and adhered to the rock.
Collected
Marginal thallus hairs straight
Marginal thallus hairs mostly in pairs
Never more than two
About 0.5 to 0.7 mm wide
Ventral face of midrib usually 2 cells wide (photo 6). Some are three
Cells generally about 30x30 microns, although some are up to 50 in length
