372 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
North Carolina: Schweinitz, type (in Curtis Herb.). 
Alabama: Peters, in Ravenel, Fungi Car. 4: 82. 
Louisiana: St. Martinville, A. B. Langlois, by. 
Michigan: Ann Arbor, C. H. Kauffman (in Mo. Bot. Gard.

California: Santa Catalina Island, L. W. Nuttall, 524, 1012, 
comm. by Field Mus. Nat. Hist. Herb. (in Mo. Bot. Gard.

Another Schweinitzian species is also noteworthy by con- 
taining more or less numerous, small, white, chalky concretions 
although not so noted by Schweinitz. This is his Exidia spicu- 
lata, a species of which I made gatherings in Vermont on rotting 
willow and other frondose species, growing from cracks in the 
bark. 
E. spiculata Schweinitz, Am. Phil. Soc. Trans. N. S. 4: 185. 
1832; Sace. Syll. Fung. 6: 776. 1888; Coker, Elisha Mitchell 
Scientif. Soc. Jour. 35: 151. 1920. 
Type: in Herb. Schweinitz. 
Growing out from cracks in the bark in elongated masses, 
with crumpled, rugose surface, about 3 mm. high, 2-4 mm. 
wide, 10-12 mm. long, between sepia and clove-brown when 
wet, shrinking when dried to a thin, fuscous-black membrane 
with veined and wrinkled surface and now showing white, seed- 
like concretions !/;-L4 mm. in diameter; basidia 9 x 6 u; spores 
simple, hyaline, curved, 9-10 x 4 y. 
On bark of fallen, decaying limbs of Salix, Betula, etc. Ver- 
mont to Pennsylvania. September to March. 
E. spiculata and E. nucleata differ from other species of 
Exidia by containing small, whitish, seed-like concretions. Æ. 
spiculata is darker-colored than E. nucleata, much thicker, 
and with a crumpled surface. The surface was described by 
Schweinitz as papillate; perhaps he used the term in a broad 
way, for I fail to find true papillae either on the surface of the 
specimen in Herb. Schweinitz or of my collections. 
Specimens examined: 
Vermont: Lake Dunmore, E. A. Burt, two collections; Middle- 
bury, E. A. Burt, two collections. 
New York: Altamont, E. A. Burt.
