1. A dispenser for a roll of paper, the dispenser comprising:
a mounting member adapted to mount the dispenser to a generally vertical wall;
a spindle assembly projecting generally perpendicularly from the mounting member and adapted to support the roll of paper thereon;
a shell surrounding at least an upper portion of the roll of paper when supported on the spindle assembly, the shell having a proximal end juxtaposed to the mounting member and a distal end spaced from the proximal end; and
a lid assembly movably mounted to the distal end of the shell for movement to and between an open configuration and a closed configuration in which the roll of paper may be installed on and removed from the spindle assembly when the lid assembly is in the open configuration;
wherein the roll of paper has a central core, the spindle assembly further comprising:
a barb on the spindle assembly projecting into the core when the roll of paper is properly sized on the spindle assembly and projecting into the roll of paper and thereby inhibiting rotation of the roll of paper relative to the spindle assembly when the roll of paper is not properly sized for the dispenser.
