very concave and narrowly recurved at margin, th ence with the margin
e re c t or w ith one wing recurved, verruculose to the base, nerve of equal
th ickness, vanishing in the apex ; cells at base minutely quadrate and
rectangular, above very small and indistinct. Perich. b ra c ts similar,
but with longer con cav e base and thinner cells. Caps, on a long slender
purple seta, e llip tico-cylindric, pachydermous, rufous-brown, when dry
and empty, exa c tly cylindric, slightly a rcu ate ; lid conic, short beaked,
a little incurved, concolorous with capsule, annulus o f three rows of
cells, peristome contorted, pale red, finally white, on a shortly papillose
narrow basal membrane.

these in fallax being pellucid, rounded and much incrassate.

I have retained this as a species, although Juratzka, Lindberg, and
others, regard it as only a variety of the last. The points of difference are
the narrower longer fragile leaves, with the margin sinuous above, denticulate
at apex, and recurved towards base.
