" Pileo stuppeo-coriaceo effuso-reflexo, pilis subtilibus erectis strigosis hirtulo pri- 

 mitus azono, demum versus marginem obsolete et concolori-sulcato, contextu alLido 

 pons medus rotundls angulatisque helvelo-pallidis, demum fuscescentibus." 



The types are poorly preserved and difficult to distinguish 

 from old plants of C. nigroinarginatiis or Coriolopsis occidcntalis.

Described from plants collected on trunks in Guadeloupe by 

 L'Herminier as follows : 



^ '' Pileo coriaceo reflexomembranaceo sessili orbiculari zonato hirsuto albo, margine 



ancipiti subtus sterHi. poris hexagonisore acutis intus extusque alutaceis, coiUextu alLo."

The types are at Paris. Very little is known of the species, 

 though it appears distinct.

 Coriolus bifonnis Pat. Tax. Hymen. 94. 1900. 



Originally described from specimens collected by Dr. Richard- 

 son on birch in North America as follows : 



** Pileo effuso-reflexo coriaceo villosocandido zonato, porismediis dentatis albidis. 

 Imbricatus. Pileus 2-4 unc. latus, 1-2 unc. longus. Pori irregulares, interdum fusco- 

 violascentes.'' 



Polyponis vwlliusaihis was described from Lea's collections in 

 Ohio, P, carolinensis from plants collected by Curtis on oak and 

 Liquidambar in South Carolina and P. chartacciis from specimens 

 found by Curtis in North Carolina on the under side of fallen 

 trunks and branches o{ Liriodcndron. According to Berkeley and 

 Curtis, Irpex epiphylla Schw. is also a synonym. 



This species is common, widely distributed and conspicuous 

 on various forms of dead deciduous wood throughout North 

 America, being usually referred to by collectors under its earliest 

 name, with P. carolinensis and P. chartacens as synonyms. P.
