the order of Polyporus dryadeus. Many poly pores have 

 what is called 'glancing' pore mouths, when the shade of 

 colour appears different according to the angle of the light. 

 This is the only species in which we have noted the same 

 effect on the context. The peculiar setae found in the pore 

 tissue are not found in the context, Other species of this 

 same genus (Oxyuris) have these setae in both context and 

 pore tissue. This plant from the American tropics is only 

 recently known from Brazil, but has lately reached me 

 from E. D, Merrill, Philippines, G. Yamada, Japan, and E, 

 Oheel, Australia,' — Lloyd. 



In Lloyd's Note 268, the following reference is made to 

 this specimen from Australia: — ''Polyporus Patouillardii, 

 sent by E, Olieel, Australia, This is the first specimen 

 known from Australia, and its occurrence is of much interest. 

 Very recently, 1907, it was named from Brazil by Rick, 

 then we got specimens from Japan, G. Yamada, then from 

 Philippines, E. D* Merrill, and now it comes from Australia. 

 (Compare Synopsis Polyporus, page 366, and Note 253, 

 Letter 56.) The Australian plant differs slightly from the 

 Brazilian plant, in fact enough to make a 'new species' if 

 one wants to multiply the species, but the difference can 

 only be noted on comparison, and of course, from one 

 specimen we cannot say it is constant. The context of 

 the Australian plant is coarser to the eye, and the micro- 

 scope shows the hyphae slightly thicker and of much deeper 

 colour. The different hyphae of the pore tissue are not in 

 evidence, and I find no setae. The spores are slightly 

 smaller, 3 x 5/^. These differences would ordinarily con- 

 stitute 'a species,' but I feel it is practically the same plant, 

 and it would only obscure the subject to propose one. The 

 history of Polyporus Patouillardii which has all developed 

 in the last three years, is evidence of what little is known 

 relatively about foreign polypores.'
