Common name: brittle cinder.

Extract from Wikipedia article: Kretzschmaria deusta, commonly known as brittle cinder, is a fungus and plant pathogen found in temperate regions of the Northern Hemisphere. It is common on a wide range of broadleaved trees including beech (Fagus), oak (Quercus), lime (Tilia), Horse Chestnut and maple (Acer). It also causes serious damage in the base of rubber, tea, coffee and palms. It causes a soft rot, initially and preferentially degrading cellulose and ultimately breaking down both cellulose and lignin, and colonises the lower stem and/or roots of living trees through injuries or by root contact with infected trees. It can result in sudden breakage in otherwise apparently healthy trees. The fungus continues to decay wood after the host tree has died, making K. deusta a facultative parasite. The resulting brittle fracture can exhibit a ceramic-like fracture surface. Black zone lines can often be seen in cross-sections of wood infected with K. deusta.
