 354 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Probably large; small fructifications laterally confluent for 

 10 cm., 1-2 cm. broad; large fructifications 7 cm. in diameter 

 and broken off on three sides. 



On frondose limbs. Arkansas to Mexico, and in Cuba. 

 August to March. 



H. leonina has been resupinate in all collections which seem 

 referable here by structure. The species is well marked by its 

 usual tawny olive color, coriaceous structure which enables it 

 to be dissected away from the substratum when moist, by the 

 distribution of the setae in the hymenium and the dark, dense 

 subhymenium, and by the broad, bright-colored hyphal layer 

 which is finally divided in the middle by a narrow, dark zone.

Fructifications resupinate, effused, thin, adnate, not crack- 

 ing in drying, between Saccardo 's umber and cinnamon-brown, 

 the margin entire, determinate ; in structure 120-260 /x thick, 

 with the intermediate layer bordered on each side by a 

 dark, dense zone — that on the under side directly adnate to 

 the substratum and that on the other being subhymenial in 

 position, 40-105 /x thick, bearing at first few setae but thick- 

 ening with age and at length having many setae starting in 

 all its parts; hyphae of intermediate layer colored, loosely 

 interwoven, 2^-3 /x in diameter; setae 75-90x7|-9 /x, emerg-
