241 



28. Poria barbaeformis (Berk. & Curt.) Sacc. Syll. 

 Fung. 6: 316. 1888 



Polyporus barbaeformis Berk. & Curt. ; Berk. Grevillea i : 53. 

 1872. 



" Totus resupinatus ; margine tenui, albo ; hymenio f ulvo ; poris 

 parvis, elongatis, dissepimentis tenuibus. No. 4519- Alabama. 

 Peters. On vine. 



" Wholly resupinate with a thin white margin ; hymenium 

 tawny ; pores ii'ich wide, but variable in size." 



Type from Alabama, by Peters, on vine. Only small scraps of 

 the original collection are to be seen at Kew. Specimens there 

 from Pennsylvania and elsewhere do not agree with the type. 

 Several fine specimens, true to type, were collected by Underwood 

 on Vitis at Auburn, Alabama, in December, 1895, and January, 

 1896. These are now in the herbarium of the New York 

 Botanical Garden. The tubes are milk-white on the edges and 

 ochraceous-isabelline within. 



29. Poria vesiculosa (Berk. & Curt.) Sacc. Syll. 

 Fung. 6 : 332. 1888 

 Polyporus vesiculosus Berk. & Curt. ; Berk. Grevillea i : 65. 1872. 

 Polyporus tenellus Berk. & Cooke ; Cooke & Ellis, Grevillea 6 : 

 81. 1878. 



Poria tenella Sacc. Syll. Fung. 6 : 331. 1888. 



Late effusus alutaceus ; poris pezizaef ormibus veluti e vesicu- 

 lis ruptis enatis. 



" Widely spreading, pale tan-colored ; pores %oo inch wide, 

 looking like minute burst bladders." 



Described from specimens collected by Peters on pine planks in 

 Alabama. Peck considered it in 1885 a variety of his quite 

 variable P. subacidus. Polyporus tenellus, described from speci- 

 mens collected by Ellis on pine boards at Newfield, New Jersey, 

 doubtless represents only a younger stage of P. vesiculosus than 

 that secured by Peters. It was originally described as follows : 



" Totus resupinatus, albus, demum ochraceus, tenuissimus, 

 pulveraceus ; margine byssino, albo ; poris angulatis, inaequalibus, 

 brevibus, ad centro confertis. 



"Allied to P. fatiscens, B. & R., very thin, with a broad white 

 sterile byssoid margin."
