117. Polyporus portentosus Berk. 



Syn. Polyporus portentosus Berk., Hook. Journ. 1845; 

 Cooke, Hand, of Aust. Fungi, No. 655. 



4 Pileus usually large, 3-4 inches in diameter, 2-3 inches 

 thick. Surface with a distinct, thin, pale yellowish crust. 

 Flesh pure white, fragile, chalky. Pores minute, pure 

 white.' — Lloyd. 



Recorded in Cooke for all the States except Queensland. 

 Some at least of the Victorian records refer to P. australi- 

 ensis (which see). 



We have a specimen of a decayed large white polypore 

 from Hill Top, found under a fallen log, which may be this 

 species. Of portion of a very large polypore collected by 

 one'of us (J. B.C.) on Flinders Island, Bass Straits, in 

 November, 1912, Lloyd says: — "I believe this specimen is 

 P. portentosus, though it is somewhat doubtful. I have a 

 plant from Geo. K. Hinsby, which agrees exactly with the 

 type at Kew. The tissue of the pores is white the same 

 as the context. In your specimen the pores are discoloured. 

 The cuticle of the type is thin but distinct. The surface 

 of your specimen is similar as to colour but does not have 

 n distinct cuticle. Spores allantoid, 1*5 x 7/* in your 

 specimen." The pores in our specimen are \ in. deep. Our 

 measurements of the spores were 5 x 1*7/*, elongated.
