A single specimen, only, of this species has been examined, which is so deeply suffused that it is n«.; 
possible to determine with certainty whether the peculiar cell which extends from the in rtion region to 
inani 
or as an abnormally developed wall-cell of the peritheeium itself. It is so closch a oeiati i with tin 
extreme tip of the peritheeium that I am rather inclined to the latter view, but it will lx nccv.ssai lo 
' younger individuals before this can be determined. The specie is not likely to he confound i with any 
other in this group by reason of the rounded form of its broad peritheeium.
