TAB. LXXX. 



/> TpHIS grows horizontally, from the fides of trees ; its firft 

 •*• appearance is in form of a convex tubercle, the fize of a 

 pea; it is then of a foft and yielding fubftance, and of a yellow 

 colour: this globular or convex figure it retains, till it acquires 

 the fize of a fmall wilding apple or crab ; it is now more firm, 

 of a darker colour without, but flill yellow within ; and the 

 tubes are not yet formed : as it advances in growth the bafe 

 fpreads laterally, a margin begins to project, and the tubes be- 

 gin to grow on the underfide; they are fo very fine and clofe, 

 that the pores cannot be difcerned by the naked eye ; while frefh 

 they are of a yellowifh colour. The upper furface is of various 

 colours, fometimes difpofed in concentric circles, grey, brown, 

 dufky, &c. The circles a little elevated, and the margin very 

 blunt. 



When the plant is full grown, the tubes are near half an 

 inch in length, of a reddifh brown colour, and an hard, dry, 

 woody fubftance, as is the whole plant ; it is perennial, grow- 

 ing and increasing from year to year. 



This fpecimen grew on the flock of a cherry tree, in 



Southowram, near Halifax,
