The Lower Basidiomycetes of North Carolina 13o 



coo-eneric. It would be just as well probably to place this latter 

 species iu the genus Exidia, which differs only in the absence of white 

 nuclei We retain it here, however, for the present. For article on 

 a supposed Naematelia see Trans. Brit. Myc. Soc. p. 143. 1899-1900. 



Key to the Species 



Growing- on deciduous v»-oods 



Orange yellow; spores subspherical N. quercina (1) 



Dull ochraceous or smoky clay to wine color; 



spores elongated as in Exidia N nucleata (2) 



Growing on pine; light flesh-color, then brownish N. encephala (3) 



1. Naematelia quercina n. sp. 



Plates 23 and 58 

 Plant forming good sized masses of crumpled and flattened folds 

 which are not hollow and which extend upward about 1.5-2 cm. and 

 laterally about 2-3.5 cm., the surface not smooth but characteristically 

 roughened all over under a lens like a cockscomb ; color orange-yellow 

 inside and out except for a thin white membrane about 0.7 mm. from 

 the surface which follows all the convolutions and gives a marbled 

 appearance to cut surface. Texture tough and firmly gelatinous, the 

 surface opaque, only the internal part translucent and paler. The 

 plant enters the bark by a flattened constricted brownish base. 



Spores orange-yellow, spherical or short-oval, smooth, 7.4-11/^ m 

 diameter. Basidia spherical, divided into four cells by longitudinal 

 walls, 15-20/x in diameter. 



This is easily distinguished by the deep color, good size, firm 

 texture, absence of hollows, and by the rough surface and \^'liite in- 

 ternal membrane. I have been able to find almost none of this plant 

 in American herbaria, the only two specimens that I am sure of being 

 the same are a plant from Ellis (Newfield, N. J.) in the Farlow Herb- 

 arium and one in the Curtis Herbarium from Society Hill, S. C. The 

 former is labelled by Ellis Naematelia sp. ? It has the same rough sur- 

 face and white interior. The latter is labelled T. aurantia Schw. but is 

 nothing like that species, which is a Dacryinyces. Its basidia are 15-19,. 

 thick, four-parted; the spores 9-10/. thick, subspherical. Naematelia 

 encephala Fr. on bark of Abies as represented in the Farlow Herbari- 

 um (Vermont, New Hampshire, etc.) has the same peculiar surface and 

 white interior. A plant from Bresadola (New York Botanical Gar- 

 den) on oak bark called by him N. encephala is like our .V. quercina 

 in surface characters and the basidia are nearly sphori.'al. 14-17/x
