PonTXJGTJESE East Afrtca. Zumbo, A. Cruz. Eeceived in 

 1913, through the Rev. C Torrend. 



The Nigerian specimen was previously referred somewhat 



dcubtfullv to Folyporus Tricholoma, Mont. {K,B, 1912, p. 142). 

 The specimen from Zumbo, however, shows the same distinctly 

 swollen base, and the African plant appears to be a good species, 

 distingitished from the American P. Tricholovia by this 

 character, and also by the slightly more fleshy pileus. 



No notes are given with either of the collections, but the plant 

 ap2:)ears to have grown on buried wood, and to have reached the 

 surface of the soil by means of the swollen sclerotium-like base, 

 such as occurs in some species of Collyhia. In the moist state the 

 plant is somewhat larger than the measurements given above, 

 which are taken from dried specimens, and the distinction between 

 the upper part of the stem and the swollen base is not so abrupt. 



Polyporus australiensis, Wakefield. 



Sessilis, basi incrassata. Pileus carnosus, semlorbicularis, 5-10 

 cm. (vel ultra) diametro, medio 1-2 cm, crassus, basin versus 

 ad 3 cm. crassus; cuticula levis, laete aurantiaca vel rubido- 

 tincta, vegeto carnosa (ut videtur), sicco cartilaginea, interduni 

 contracta, interstitiis pallidioribus. Fori eoncolores, carnosi, 

 siccitate contracti, circa 1 mm. diametro, 2-9 mm. longi (in sicco) - 

 Caro pororum longitudine duplo vel quadruplo crassior, pallida 

 luteo-aurantiaca. Sporae non visae. 



Australia, Queensland : Coomera Eiver, on logs, C, T. 

 White (received through Mr. F. M. Bailey) ; Toowoomba, 

 Grampians, Snllivan (in Herb. Kew as P. portentosus, B.) ; Geo- 

 graphe Bay (in Herb. Kew as P. stypticus, Fr.). Victoria: 

 Campbell (in Herb. Kew as P. retiporus, Cke.). 



A very distinct species, near to P, sulphureiiSy and said to have 

 a very strong odour when fresh. It differs from P. portentosus^ 

 retiponis^ and stypticiis, with which it was confused in the early 

 records quoted above, in the brilliant orange-yellow tints in pileus 

 and pores, and in the yellowish flesh (Hidgway, tab. Ill, 15f ).
