BURT—THELEPHORACEAE OF NORTH AMERICA. VII 523 
This species is closely related to 8. pseudopedicellatum 
but is more deeply colored, has more opaque hyphae, and 
smaller spores and spore-bearing organs. No lateral pro- 
tuberances or papillae have been observed on the latter. 
Specimens examined: 
Alabama: Montgomery, R. P. Burke, two collections (in 
Mo. Bot. Gard. Herb., 20421, type, and 20693). 
6. S.sublilacinum (Ellis & Ev.) Burt, n. comb. 
Thelephora sublilacina Ellis & Ev. State Univ. Iowa, Lab. 
Nat. Sel. Bul. 13:67. 1896; Sace. Syll. Fung. 14:214. 1900. 
Type: in N. Y. Bot. Gard. Herb. 
Fruetifieation resupinate, effused, coriaceous, dry, not sep- 
arable from the substratum, glabrous, shining, olive-brown, 
darkening to dark neutral gray; in structure 3-layered, with 
(1) a layer next to the substratum, 40-60» thick, of closely 
crowded, longitudinally arranged hyphae concolorous with 
the fructification, 4-414, in diameter, which form (2) a layer 
of pillars 40-60» in diameter, about 2-4 to a millimeter, whose 
hyphae spread apart at the outer end and form and support 
(3) the hymenial crust about 60. thick, densely interwoven 
throughout, with even, thick-walled, concolorous hyphae 3- 
314» in diameter on the under side, Ән in diameter, nearly 
hyaline, and densely, longitudinally interwoven at the sur- 
face; probasidia, spores or other organs not present in the 
type. 
Fruetifieation about 14 em. in diameter, ?4 mm. thick. 
On living branches. Nicaragua. 
The type specimen of this species, when viewed from above, 
agrees so closely with Ше cotype of S. Spongia in color and 
habit that one is strongly disposed to regard the two speci- 
mens as of the same species. S. sublilacinum has, however, 
the coarser hyphae, a three-layered structure, and distinct 
pillars. It seems best to regard it as a distinct species, at 
least until fertile specimens define the species more definitely. 
Specimens examined: 
Nicaragua: С. L. Smith, 108, type (in N. Y. Bot. Gard. 
Herb.).
