Woods and shaded banks, in the North of England, Wales and Ireland.
Not unfrequent in Scotland. Fr. June.—When seen under a
microscope, the margins and nerve of the leaf are of a deep blood colour
and the calyptra is of a red or orange hue. No one has studied this
groupe of Mosses more successfully than the Rev. Mr. Dalton of Croft,
and to him I am indebted for much information respecting the various
species of it.

Marshy places and in wet woods. Fr. Apr.—The whole plant is of
a lurid yellowish -green colour, the leaves very narrow, the lid hetni-

adhesion to the seta below the capsule, as in Timmia cucullata, is a
common occurrence in this species.
