Polyporaceae. 



This large group of fungi which is most important in phytopatho- 

 logical respect has particularly caught the interest of Rostrup, and 

 many specimens of Polyporaceae are contained in his collections. Be- 

 sides Rostrup C. Raunkiser has also contributed much to procure in- 

 formation as to what species of Polyporus occur in Denmark. Raun- 

 kiaer has examined them very closely and described their microscopi- 

 cal characters, but he has published nothing concerning them. Raun- 

 kiaer's most accurate observations of the size, shape and colour of the 

 spores, of the character of the mycelium etc. are of great value, but 

 I am sorry that I cannot introduce them here to a greater extent than 

 has already been done.
