Patches 1-2 inches wide, reddish-brown. Stems minute. 
The auricle is one third of the leaf in size. The diameter of 
the perigonia three or four times that of the full grown 
shoots. Perichetial leaves oblong, incurved, apiculate, the 
sides of their lesser lobes reflexed, as are those of the stipular 
leaf ; but the margins of all are entire; except that on the 
lesser lobe, and between it and the stipule, are one or two 
very short processes. Calyx twice as long as the periche- 
tium, The present greatly resembles Jung. lobulata, Hook. 
It differs by the minuter size, by the narrower base of its 
calyx, by the less decidedly triangular shape of the calyx, 
which too is wider above and by the acute and even apiculate 
leaves of the perichætium.
