" Resupinate, white, about an inch broad, consisting almost en- 

 tirely of tubes. Margin obsolete. Pores small, round or slightly 

 sinuated, their edge very obtuse. 



" A distinct but not very remarkable species, allied most to 

 P. vulgaris, but differing in its thick dissepiments and the obtuse 

 edge of the pores." 



Type from South Carolina, by Ravenel, on decayed oak 

 branches and frequently on the disks whence twigs had been 

 broken off. Seen at Kew and Upsala. The description was 

 worked over for Grevillea i : 54. 1872, but too much stress was 

 placed in both descriptions on the obtuseness of the dissepiments. 

 It is quite distinct from Porta dryina.

Poly poms rivulosus Berk. & Curt. Jour. Linn. Soc. 10 : 318. 1868. 



" Candidus, effusus, carnosus (siccus contractus rimulosus), 

 margine tenui tomentoso ; poris mediis rotundis, dissepimentis 

 crassis pruinosis. 



" On dead Polypori. Margin at length more or less free. Pores 

 Yqq inch in diameter." 



Type from Cuba, by Wright, on dead polypores. Parts of the 

 original may be seen at Kew and Paris. 



27. Porta ANAECTOPORA (Berk. & Curt.) Sacc. Syll. 

 Fung. 6: 326. 1888 



Polyporus anaectoporiis Berk. & Curt. Jour. Linn. Soc. 10 : 318. 

 1868. 



Totus resupinatus, margine tenuissimo ; poris magnis hian- 

 tibus saepe decurrentibus (siccis rufis), dissepimentis rigidis sub- 

 acutis. 



" On dead bark. Pores %2-%8 inch in diameter ; their fructi- 

 fying surface waxy." 



Known only from specimens collected by Wright on dead bark 

 in Cuba. Very peculiar, with large shallow tubes like those of 

 Favolus, which become reddish when dry.
