Hab. — Rare, on damp shady rocks by streams. First recognized as British from 

 specimens collected on rocks near the Strid, Bolton woods, Yorkshire, April 1858 ! 

 Egleston, Tees-side, J. G. Baker, 1856 ! Teesdale, W. Mudd ! 



Originally discovered by Funck in Carinthia, and found sparingly in Switzerland, 

 Ha/mpe ; and Savoy, Br. Mueller, fr. ! 



Tnfts depressed, scattered, resembling Jung, ventricosa or Jung, 

 cc^itata in habit, of a sordid green colour, frequently creeping 

 among other mosses and hepaticse, e. g. J. rvparia, J. MuUeri, and 

 Chiloscyphus polyanthos. 



Stems (f. 27, 1) stout, succulent, pale-brown, simple or innovant- 

 furcate ; lower two-thirds creeping, the upper third ascending, 

 generally concealed by the amplexicaul bases of the leaves ; stolo- 

 niferous at the base, the stolons naked or ramentose. 



Rootlets white, capillary, abundant on the creeping portions of 

 the stems. 



Shoots (f. 27, 2) about -i" in length, by -j^" broad, of nearly equal 

 diameter throughout except in fertile individuals, where the ter- 

 minal leaves are somewhat larger. Undulate and tumid, especially 

 when dry ; rounded and smooth on the ventral aspect, the lower 

 lobes of the leaves not being at all reflexed. 



Leaves (f. 27, 3, 4) loosely imbricated, alternate, with an upward 

 and forward direction, so as to appear slightly secund ; when 

 opened out cordate in form, about half a line long, the base saccate 

 and amplexicaul ; divided for a short distance, not exceeding one- 

 fourth of their length, into two nearly equal concave lobes, which 

 are either cuspidate and apiculate or obtuse. 



Inferior lobe (f. 27, 5) roundish-ovate, concave, the basal angle 

 contracted, but not at all reflexed. Lohule (f. 27, 4) ovate, 

 acute, crossing and concealing the stem, patulous, the margin 

 erect or reflexed, and, as in the larger lobe, more or less repand- 

 undulate.
