POLYPORUS BOUCHEANUS (Fig. 506). Pileus fleshy, 

 plane or cyathiform, yellowish with small squamae. Pores large, an- 

 gular, decurrent, white. Stipe short, pale, hirsute, excentric or often 

 lateral. Pores 7x12, hyaline, smooth. 



This is a rare species in Europe and it appears to me to have been badly 

 confused. The only type (Fig. 506, the long stemmed one) is at Berlin. It 

 was called Favolus Boucheanus and it appears in Saccardo under Favolus. It 

 was described by Klotzsch as having a dark stem and was put in Melanopus by 

 Fries. Polyporus Forquignoni as called by Quelet is the same plant I think 

 although said to have a stem "white as. snow." I think the truth is the stem is 

 neither white nor black, but concolorous-, hence does not come in this section, 

 but I place it here as I think it is so closely related to squamosus. In fact, ex- 

 cept as to its small size and pale stem, it is squamosus as to color, flesh, pores, 

 texture and spores. In England and the United States Polyporus Boucheanus 

 has been confused with Favolus europaeus with which it has no relation and to 

 which it has but little resemblance.

Polyporus tasmanicus. 



POLYPORUS TUMULOSUS. This is known from but one col- 

 lection made in Australia and preserved at Kew. It is quite a dis- 

 tinct thing with a pileus resembling in some respects that of Polyporus 

 betulinus. It has soft, white, flesh and a thin, papery, smooth cuticle. 

 The stems are short, thick and mesopodal. They are so covered with 

 adhering dirt that it can not be told whether or not they belong in the 

 section with black stems. The pores are large, irregular and apparently 

 have turned black in drying. Spores not found by me.
