'Pileus thin, smooth, with dull, soft surface. Context, 

 when dry, hard, firm, but brittle; white when fresh, darker 

 when dried. Pores small, round, irregular, white at first, 

 but becoming fuliginous, or dark, in drying. Spores 2\ x 

 5 mic. Polyporus fumosus is quite a frequent plant, usually 

 on willow. It is the same, in fact as Polyporus salignus, 

 with small pores. When it is in its prime, and growing, it 

 is white; but on drying it turns more or less smoke coloured. 

 It is often confused with Polyposis adustus, and many 

 specimens in the museums are labelled as being Polyporus 

 fumosus. Dried specimens may be confused sometimes, 

 but the difference is marked in the fresh plant. Polyporus 

 adustus has deep, smoke coloured pores when growing; 

 Polyporus fumosus lias white pores, turning smoky in 

 drying, but when dry rarely deep enough in colour to be 

 confused with Polyporus adustus. With Polyporus salignus, 

 however the case is different. It is the same plant as 

 Polyporus fumosus with larger pores. When growing white, 

 it is usually called Polyporus salignus. In drying or after 

 it turns 'smoky' it becomes Polyporus fumosus. When 

 fresh, Polyporus fumosus has a pleasant odour, as noted 

 by Persoon.' — Lloyd. 



Under the two synonyms given above, Cooke records this 

 species respectively for Tasmania and Western Australia.
