1921] The Thelephoraceae of North Carolina 177 



Not rare on rotting oak stumps and logs. The species is easily- 

 recognized by its good size, complicated structm'e, tawny and tomen- 

 tose surface and dark hymenium which turns red at once when 

 bruised. It differs from S. sanguinolentum in tawny color and growth 

 on oak. The latter is pallid and grows on pine.

2. Stereum sanguinolentum (A. &. B.) Fr. 



Plate 35 



Largely resupinate, the upper margin reflexed and bracket-like, 

 in our plants extending only about 4-5 mm.; surface of the free caps 

 inherently fibrous, radiately striate, zoned lengthwise by thin brown 

 lines, the remainder nearly white or brown, the thin margin white; 

 flesh leathery, tough, elastic, thin. Hymenium more or less wrinkled 

 and ridged, when young whitish (very pale fawn) sooner darker 

 through light fawn to dusky fawn; when bruised in the fresh state 

 immediately exuding a deep red juice which stains the surface, later 

 the stained parts becoming dark dusky brown with only a tint of red. 



Spores (of No. 3967) white, sausage-shaped, 2-3 x 6-8.5[jl. 



Easily distinguished from others that turn red by growth on pine 

 and different color. Our plants form patches about 1.5-2 x 1.5-4 

 cm., some with and some without the narrow reflexed margin. If 

 soaked again after drying the hymenium turns red almost all over 

 and on drying again darkens to a very deep brown, the margin only 

 remaining white.

 Plants bracketed from a resupinate layer, extending about 1.5-5
