You stand at the begining of a narrow hallway, but not so narrow as to
force you to stand sideways to pass.  The hall is small enough, however,
that your passing causes the moss that has formed here to fall upon your
clothing.  The narrow, moss-covered hallway continues to the east.  
     A clump of edible moss grows on one of the walls.
