A very noxious parasite, the mycelium penetrates the wood of the 

 trunks, and the sporophores break forth through the bark from the 

 very base of the trunk and up to 5 m high most frequently arranged 

 in a helix (R 85 d). Schroeter is mistaken in describing the resupinate 

 form often to be found on dead branches of Fagus as Polyporus 

 obliquus; Rostrup also uses the same name (R 02 a). It is a strange 

 fact that this crusty form is almost always infected by Nectria cos- 

 mariospora, which never occurs on the projecting form. Rostrup has 

 also indicated this form as Polyp, rufus, Redbrun Poresvamp (R 69 '^).
