536 J. B. CLELAND AND E. CHEEL. 



Island, Hawkesbury River (March — spores white, pear- 

 shaped, 3*6 to 4*2 x 2'5/x). 



145. POLYPORUS DRYADEUS PerSOOD. 



'Pileus sessile, often large, a foot even in diameter, 2 to 

 3 inches thick. Surface with a thin but distinct crust, 

 brown. Context medium, soft, reddish-brown colour (Sudan 

 brown), with a sheen. Pores small, round, subconcolorous, 

 1 to 2 cm. long. Setae straight, rare, 8 x 40 mic. Spores 

 globose, smooth, hyaline or pale coloured, 7 to 8 mic. '-Lloyd. 



One of us (J.B.C.) has collected this species growing 

 about ten feet up on the trunk of a Eucalypt in the Mount 

 Lofty Range, South Australia, in July 1914. Though it 

 has not been recorded for New South Wales, its description 

 is given here, as in other parts of the world it is a destructive 

 timber parasite. Lloyd, in identifying our specimen, 

 states: — 'This grew on Eucalypts and is the first specimen 

 known from Australia. It appears at first sight to the eye 

 a little different from the European plant, surface with a 

 pale more pronounced crust but microscopic features agree 

 exactly. There is an indication on the specimen of a 

 mycelial core, a feature only known on the related species 

 Polyporus corruscans of Europe.' The spores of our 

 specimen are oval, 8*5 to 8*8 x 6 to 7fX.
