 Tab. 79). Not uncommon. Distribution general. 



On trunks of living trees, more especially the oak in this 

 country, but it has also occurred on hornbeam and beech. A 

 wound parasite, the sporophores appearing for many years in 

 succession at the same spot. Popularly known as the beef- 

 steak fungus on account of its " flesh" resembling a beef-steak 

 or between that and liver in colour and substance when cut. 

 It grows in thick flaps, and sometimes attains a large size, one 

 specimen is recorded as weighing nineteen pounds. Edible, 

 but rather coarse, and not of a particularly pleasant flavour.
