fusca. Operculum subulatum, capsula subaeque longum. Ca- 
lyptra badia, striata, glabra, mitriformis, a basi usque ad me 
dium in lacinias longas tenues fissa. Peristomium simplex,

This is another species with the same habit as that figured at 
Tap. XXIV., and with the same remarkable calyptra. A similar 
ealyptra Mohr has attributed to a moss which he says is nearly: 
related to Aniclangium cirrosum of Hedwig,. and to another from 
Oronoko; but in both these, which he has included in his genus 
Ulota, there is an inner fringe exactly as in Neckera. The pre- 
sent plant differs from O./ongipes in the lengthened narrow leaves,. 
the shorter fruitstalks, and distinctly sulcated capsules.
