73. Poria cavernulosa (Berk.) Cooke, Grevillea 14: 113. 1886 



Polyporus cavernulosus Berk. Jour. Bot. & Kew. Misc. 8: 235. 

 1856. 



Collected on dead branches at Panure, Brazil, by Spruce and 

 described as follows: 



" Resupinate, orbicular, at length confluent, of a dirty fawn 

 colour, darker in the centre, rigid; margin narrow, formed of 

 matted down, but not byssoid; pores %5 of an inch across, sub- 

 hexagonal ; edge rigid, sometimes elongated at the commissures, 

 sometimes slightly waved." 



Original specimens seen at Kew are not distinct from resupi- 

 nate forms of Trametes versatilis Berk., although a totally dif- 

 ferent plant was found under this name at Paris and in the Fungi 

 Cubenses Wrightiani. P. byssoideus Jungh. in the Persoon her- 

 barium at Leiden also seemed to me the same as T. versatilis, 

 while Romell says that Poria Dusenii P. Henn. belongs in the 

 same category.
