millim. d'epaisseur, creme avec un reflet grisatre ou violace, 

 entoure d'une marge sterile, tres mince, lisse et d'un blanc de 

 craie. Pores extremement petits (environ 60 de diametre), 

 superficiels, anguleux-sinueux, profunds de 40 a 50/^- Trame 

 blanchatre, traversee dans toute son epaisseur par les cloisons qui 

 sont tres minces (30 a 50//.) et entieres." 



Type from Guadeloupe, by Duss, on a trunk of Richeria 

 grandis. Although I have visited Dr. Patouillard's private her- 

 barium at Neuilly several times, I have no record of having ex- 

 amined this species.

 Fung. 6 : 321. 1888 

 Polyporus decolorans Schw. Trans. Amer. Phil. Soc, 4 : 159. 1832. 



" P. minutus, 3-4 lin. diametro, sed longe lateque confluens, 

 non effusus, sed quasi totaliter affixus, margine inflexo libero, 

 membranaceo. Primum moUusculus, albus, decolorans ac sordide 

 brunneus devenit. Poris magnis subflexuosis, e forma orbiculari 

 in flexuosam confluit. Tenerrimus." 



Type from Bethlehem, Pennsylvania, by Schweinitz, on fallen 

 bark. Seen at Philadelphia but not at Kew. 



24. PoRiA CLATHRATA (Berk. & Curt.) Sacc. Syll. 

 Fung. 6: 312. 1888 

 Polyporus clathratus Berk. & Curt. ; Berk. Grevillea i : 54. 1872. 



" Niveus, effusus, late cribrosus ; parietibus cribrorum laccato- 

 laevibus ; poris punctif ormibus, dissepimentis crassis obtusis. 

 No. 3656. Louisiana. Dr. Hale. Widely effused, the hymenium 

 with large apertures, the walls of which are smooth and honey 

 colored. Pores ^2 inch wide." 



Type from Louisiana, by Dr. Hale, on trunks. Poorly pre- 

 . served at Kew and seems abnormal, or at least peculiar. The 

 " large apertures " are difficult to explain.

 Fung. 6: 297. 1888 

 Polyporus cremor Berk. & Curt. Hook. Jour. Bot. i : 104. 1849.

 dissepimentis crassis, acie obtusissima.
