BURT — THELEPHORACE^ OF NORTH AMERICA. Ill 371 



Specimens examined: 

 South Carolina: Aiken, Ravenel, 1714, type (in Kew Herb.). 



i6. C. Ravenelii Berk. Grevillea 2: 5. 1873. Plate 19. fig. 14. 



Type: type and cotype in Kew Herb, and in Curtis Herb, 

 respectively. 



Fructifications single or gregarious, sessile, subglobose, some- 

 what flattened, depressed at the pore, minutely hairy under a 

 lens, vinaceous buff; hairs minutely rough, about 300 ju long, 

 4 n thick, tapering towards the free end, olive-yellow under the 

 microscope; spores hyaline, or perhaps very slightly colored, 

 even, broadly ellipsoidal, 10-12 x 6-8 /x. 



Fructifications 0.6 mm. high, 0.8 mm. broad; pore 0.15 mm. 

 in diameter. 



On bark of Carya. South Carolina. 



The specimens of this species which I have seen have been on 

 thick and cracked portions of bark apparently from large 

 branches or the main trunk of the tree. Sometimes only one 

 fructification occurs on a piece of bark a centimeter square; 

 sometimes such a piece bears from 3 to 6 fructifications with 

 some of them barely in contact with one another. The type 

 specimen contains so few fructifications that I made a micro- 

 scopic preparation at Kew Herbarium from the specimen dis- 

 tributed by Ravenel in Ellis, N. Am. Fungi, 721, which seems 

 to me to be certainly the same species as the type. Berkeley 

 described the spores in his original description as ''elliptic, 

 .00025 (in.) long"; I found them about twice this length in my 

 preparation referred to and also in a preparation recently made 

 from the specimen in Ravenel, Fung. Am., 130, in the Mo. Bot. 

 Gard. Herb.
