Stems rather short, innovately branched, the branches tlagelliferous (as in JSr. Wm- 

 iicHin. BiiAXD.). Lea\'es l)roadly ovate or ovate-lanceolate, entii'c, cusj)idate by the stout 

 excurrent costa, broadlj' revolute on tift' margin, with a narrow subsolid l)orde]'. Cap-

 dry, constricted under the mouth, pale, becoming light fuscous. Operculum rather 

 large, convex, mutic or very minutely papillate, pale, with a narrow rim comixised of 

 2 or 3 rows of slightly ditferenl (pale) cells, .\nnulus rather narrow foi' the genus,

 leaves more or less distinctly margined, and often rather broadly revolute on the mar-

 api)ears to be too near Br. Miihleiiberku, Br. Eu. (Br. Muhlcnberkii has been found in 

 the mountain ravines of Pennsylvania {Wnlle <f- 7^///). but without fruit.)
