bordered on each side by a narrow, dense, dark zone; hyphae 
3-34 шіп diameter, colored, thick-walled; setae 40-70 6-7 и, 
emerging up to 30 p, tapering from the base, abundant but not 
erowded; eolored para- 
physes 1-2 џ in diameter, 
e with pinnatifid tips, are con- 
spieuous in the hymenium;

in preparations of sections. 
Fructifications about 1-3 em. in diameter. 
On bark of fallen frondose limbs. Georgia to Louisiana, in 
Mexieo, Cuba, and Jamaiea. August to April Apparently 
common. 
H. pinnatifida has some resemblance to resupinate H. ru- 
biginosa, but the setae of the former are less conspicuous with 
the aid of a lens; the presence of colored paraphyses with 
pinnatifid tips distinguishes H. pinnatifida from all other non- 
stratose species.
