This fine moss is very close to M. Unuirostris, but is readily distinguished 

 by the dilated base of the leaf and very different areolation. The fruit was 

 unknown until Schimper detected one or two old capsules, which had lost 

 their peristomes, and fig. 5 and 6 are copied from his drawings.
