Plantæ fluctuantes, formis vernalibus præcedentis speciei simillimæ, colore plerumque e viridi sericeo-aurescente.
Caulis pedalis et ultra, laxius foliosus, multoties divisus, divisionibus vage vel versus apicem subpinnatim ramulosis.
Folia nullatenus biformia erecto-pateutia, baud manifeste trifaria, elongato-laneeolata, concava, mollia, basi amplexicaulia, apice lenissime serrulata; cellulis mediis minutis flexuoso-line-aribus, apicalibus brevioribus latioribus, illis ad basis angulos multo majoribus oblongis subventricosis.
Flores dioici: feminei sat numerosi prope caulis basin siti; antheridiis 6–10, cum paraphysibus longioribus 10–12 septatis.
Capsula brevi-cylindracea, tenui-membranacea, perichætialibus internis primum ultra operculum maturum porrectis demum ætate eroso-abbreviatis arete involuta; peristomii granuloso-papillosi dentibus apice binatim coadunatis 20–25-articulatis, ciliis superne trabeculato-connexis inferue liberis appendiculatis; operculo elongato-conico; calyptra generis.

Var. β. ramosior; ramulis magis elongatis flexuosis; foliis angustioribus confertioribus minus patentibus capsula operculoque longioribus; dentibus peristomialibus remotius articulatis. Facile in formam typicam per intermedias remanans.
Var. γ. gracilescens; minor, tenuior, F. disticham valde referens, distinctissima tamen capsula plane alia.
