Murrill: Polyporaceae of North America 647 



that it differs from Polystictiis Didnchsenii Fr. (Nov. Symb. 76. 

 185 1), found on the island of Bora-Bora, in its far smaller pores. 



The present species is easily known by reason of its beautiful 

 lilac-colored hymenium. It is quite well distributed in tropical 

 America on decayed hardwood trunks.

Described as follows from Panure, Brazil, collected on decay- 

 ing trunks by Spruce : 



i 



" Albus, suborbicularis, postice decurrens, tenuis, papyraceus ; pileo subtiliter 

 pubescente sulcato-zonato ; hyraenio concoJori ; poris angulatis miputis ; dissepimentis 

 tenuibus.*' 



" An elegant species, allied to P. hirsufus^ but much thinner, with finer pores and 

 destitute of distinct hairs.'

Twelve years later, Berkeley described the same plant from 

 Cuba under another name, using almost the same words. 



10. Coriolus ilicincola (B. & C.) 



Poly poms ilicincola B. &. C Grevillea 1 : 52. 1872. 



Described from specimens collected by Peters in Alabama on 

 the bark of Ilex opaca. The types at Kew are not well preserved. 

 Specimens in the Ellis collection agree in all respects except the 

 sinuate pores. 



II, Coriolus Drummondii (K1.) Pat. 



Poly poms Drummondii Kl. Linnaea 8 : 487. 1833. 

 Coriohis Drummondii Pat. Tax. Hymen. 94. 1900. 



The type plants were collected by Drummond on trunks near 

 New Orleans, Louisiana. Klotzsch saw them in Hooker's her- 

 barium. They are now in a fair state of preservation at Kew. The 

 plant has not since been collected in Louisiana and I have not seen 

 anything closely resembling it in recent collections from the 

 southem United States.
