114 THE WOODLANDS. 



Tremella of a deep yellow colour, sometimes about 

 the size of a filbert, at others as large as a walnut ; 

 the surface deeply furrowed, waved, and convoluted, 

 when moist, but shrivelling when dry to one-tenth 

 the original size, and scarcely recognisable. 1 



YELLOW TREMELLA. 



BULGARIA. 



It is not unusual to see prostrate trunks of beech 

 and oak when lying in damp situations sprinkled 

 with hundreds of blackish fungi, soft and yielding to 

 the touch, but much firmer than the Tremellas. 

 These bodies range from less than half an inch to 

 more than one inch in diameter, are regularly dis- 

 coid, like large buttons with a thick stem. Externally 

 they are of a bay brown colour, but the flat disc on 

 the top is of a dull black, and usually in groups 

 of two or three together. The name of black 

 " Bulgaria," which is applied to them, is one which 

 for various reasons is not likely to be forgotten. 3
