Type: in Kew Herb. and Curtis Herb. 
Fructifications resupinate, effused, becoming narrowly re- 
flexed, lobed, coriaceous, rather rigid, with the upper surface 
of the reflexed part velvety, snuff-brown at first, later Benzo- 
brown; hymenium Benzo - brown, 
ТҮҮ ochraceous-tawny near the margin; 
ЗА in structure 300—500 џ thick, with the 
SNS SS setigerous layer 30-45 д broad and 
ые уһ the intermediate layer compris- 
ing most of the thickness of the fruc- 
tification and bordered on each side 
by a narrow, dense, dark zone, of 
which that on the setigerous side is 
the less distinct; hyphae of inter- 
mediate layer 34 y in diameter, 
colored, somewhat interwoven and 
longitudinally arranged; setae con- 
ical, 30-45 6-8 и, larger ones sometimes found, emerging up 
to 30 р, very numerous, starting from all portions of the 
setigerous layer; spores probably hyaline, even, 4X 13-2 д. 
Fructifications with reflexed portion 3-1 em. long, resup- 
inate over areas 4x 1-11 cm. 
On dead wood and bark of frondose species. Cuba and 
Venezuela. March. Rare. 
On account of the dark zones bordering its intermediate 
layer, H. rigidula belongs in the small group, of which H. 
tabacina and H. rubiginosa are more common examples; it 
is distinguishable from all these species by the great number 
and erowded arrangement of its setae in the setigerous layer, 
rigidula.
