DESCRIPTION OF PODAXON PISTILLARIS. 298 
I find here and there a thread containing a single spiral 
filament, or itself breaking up into a flat spiral and twisted 
fillt. In that species too the flocci are in general much 
more undulated and sometimes even curled. "There can be 
no doubt but that this, like other Podaxineæ, belongs to the 
division of sporophorous Fungi; but a proper comparison 
and correct appreciation of the different parts cannot be 
made without the examination of specimens in a much earlier 
stage of growth than any which have hitherto been submitted 
to the mycologist.—M.J.B.
