 Described from Australian specimens by Lloyd (Mycol. 

 Notes, No. 43, 1916, p. 601). 



Specimens have been identified for us by Lloyd. We 

 have found it growing as a large mass at the burnt base of 

 a dead tree at Katoomba in June, 1916 (spores 4*8 x 2*5 to 

 3*5/*). We have also specimens on burnt wood from Mount 

 Wilson in June, 1915 (spores 4 to 5 x 2*5 to 3'4/*).

50. Polyporus (Spongiosus) Schweinitzii Fries. 



This species is parasitic on the roots at the bases of tree 

 trunks, and is said to be a destructive parasite. It may be 

 readily recognised by its irregular cap, sometimes four or 

 more inches across, which is rugged and has a bright fer- 

 ruginous colour. The stem is sometimes very short, some- 

 times several inches long, rugged and irregular and dark 

 ferruginous brown. The pores are rather small, run down 

 on to the stem and are greyish-yellow. Often the caps of 

 several adjacent plants grow into each other.
