specimen so named in the Desmazieres collection at Paris proved 

 to be Coriolellus septum. 



3. PoRiA Salviae (Berk. & Curt.) Sacc. Syll. 

 Fung. 6 : 311. 1888 

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



"Effusus, mollis, albus, fere totus e poris minimis flexuosis 

 constitutus ; dissepimentis tenuibus. No. 2602. Car. Inf. On 

 Salvia, surrounding the branches, consisting almost entirely of 

 the minute flexuous pores ; dissepiments thin ; pores %oo i^ch in 

 diameter. Allied to P. vaporarius." 



Type from South Carolina by Ravenel on sage. Seen at Kew 

 and also in the Ellis Herbarium. An abnormal, cellular form 

 almost devoid of context. 



4. Poria candidissima (Schw.) Sacc. Syll. 

 Fung. 6 : 310. 1888 



Polyporus candidissimus Schw. Trans. Amer. Phil. Soc. 4: 159. 

 1832. 



P. effusus ; membrana tenuissima, bombycina, sed tamen 

 detrahenda. Poris maximis demum obliquis, cum membrana 

 candidissimis. Ad Polystictas pertinere videtur, sed membrana 

 detractabilis obstat." 



Type from Bethlehem, Pennsylvania, by Schweinitz, on de- 

 cayed wood. At Philadelphia but not at Kew. Thin, white, like 

 a cobweb, with a shallow network of tubes resembling holes in 

 a veil. 



5. PoRiA calcea (Schw.) Sacc. Syll. Fung. 6: 330. 1888 

 Polyporus calceus Schw. Trans. Amer. Phil. Soc. 4: 159. 1834. 



Known only from specimens collected on a fallen trunk in 

 Bartram's garden, Philadelphia. Schweinitz thought these speci- 

 mens the same as Polyporus vulgaris calceus Fries, Syst. Myc. i :. 

 381. 1 82 1, which variety he considered sufficiently distinct to de- 

 serve specific rank. The American plant, however, has no such 

 close connection with the plant known to Fries. Poria calcea 

 Berk. & Br. was used later for a Ceylon species.
