This singular species of Grimmia has much the habit, as it
has the mode of growth, of Cindidotus fontinaloides, or of some
species of Fontinalis in an injured state. There are no leaves,
nor the appearance of there having been any on the main stems,
whilst the short lateral branches are thickly terminated by them.
These leaves are moreover very thin and membranaceous. The
capsule is very small in proportion to the plant, and quite concealed
by the perichaetial leaves. The teeth are much curved inwards,
pale coloured, obtuse, and jagged or cleft, like Grimmia
ovala,
