BURT—THELEPHORACEAE OF NORTH AMERICA VI 231 
On decaying wood. New Hampshire to Maryland. Sep- 
tember to January. Probably frequent. 
H. atroruber is one of our finest species of the genus. It 
is conspieuous by the dark red central region bordered by 
a melleus (in the sense of ‘Chromotaxia’) margin. This 
margin was not noticed by Peck in the original description 
but is present on one side of his type. Specimens of H. 
atroruber lacking the characteristic melleus margin may be 
distinguished from H. rubiginosus by the coarser, darker- 
colored, thicker-walled hyphae of the former species.
