dm. (4-8 inches) long, taper-pointed, rarely rounded at the apex, 
wedge-shaped, rounded or heart shaped at the base, margins coarse-

Distribution. Maine to Ontario, south to Alabama and Tennes- 
see. It is believed that in Indiana it is confined in its distribution 
to the knob area of the south central part and extending as far 
north as Brown County. It is frequent or common where it oc- 
curs and in Clark, Floyd, Scott and Washington counties it is gen- 
erally associated with Pinus virginana. 
The published records of the distribution are as follows: Clark 
(Baird and Taylor) and (Smith); Dearborn (Collins); Franklin 
(Meyncke); Gibson and Posey (Schneck)*; Hamilton (Wilson)**; 
Miami (Gorby)**; vicinity of New Albany (Clapp); Tippecanoe 
(Cunningham)***; Wayne (Petry and Markle)****. 
Additional records are: Clark (Deam).
