It has an amply developed felt-like mycelium serving as a subi- 

 culum to the black, cupuliferous perithecia. The mycelium spreads on 

 old wood and on the bare ground. Besides in Denmark it has only 

 been found twice in Sweden, in Upsala (Romell) and in Stockholm 

 (Hamberg).

As it is furnished with two-celled spores and with paraphyses it 

 ought to be classified as Herpotrichia. Its attacks are very destructive 

 to trees at the age of from ten to twenty years when they are growing 

 too densely (see R 02 a). Rostrup fotind it in this country in 1884 

 the same year as Hartig recorded it from Germany.
