370 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Fructifications solitary or clustered, nearly sessile, pulvinate, 
plieate-rugose, solid, drying cinnamon to Natal-brown externally 
and white and fibrous within; basidia 12-15 y in diameter; spores 
hyaline, even, subglobose, 8-10 x 7-9 y. 
Dried fructifications 3-10 mm. in diameter, 3-5 mm. high. 
On dead, fallen branches of coniferous species. Ontario to 
North Carolina. August. Rare. 
Naematelia encephala has small fructifications which are 
nearly subglobose, scarcely more than rugose on the surface 
and not deeply divided; attachment to the substratum is usually 
by a point rather than by a broad resupinate surface; the sub- 
stratum is pine or spruce in all specimens known to me. 
Specimens examined: 
Exsiceati: Berkeley, Brit. Fungi, 291; Krieger, Fungi Sax., 
1008; Sydow, Myc. Germ., 58. 
England: Berkeley, Brit. Fungi, 291. 
Germany: Saxony, H. & P. Sydow, in Sydow, Myc. Germ., 
58; Winterberge, G. Wagner, in Krieger, Fungi Sax., 1008. 
Canada: Ontario, Temagami, H. von Schrenk (in Mo. Bot. 
Gard. Herb., 57052). 
New Hampshire: Tuckerman’s Ravine, W. G. Farlow (in Mo. 
Bot. Gard. Herb., 5352). l 
Vermont: Middlebury, E. A. Burt. 
Under the name Tremella nucleata Schweinitz described a 
species of quite different structure from Naematelia encephala 
and N. aurantia Fries transferred this species to Naematelia 
because dried specimens contain scattered, white, spherical or 
lens-shaped calcareous masses imbedded in the fructification. 
These masses were termed nuclei by Fries but they are not of 
organic nature, being merely concretions! of calcium oxalate 
present in the gelatinous fructification and quite different from 
the white fibrous structure which forms the interior of N. aur- 
antia and N. encephala. Some species of Exidia contain cal- 
careous masses similar to those of T. nucleata, and since the 
spores of the latter are of the elongated form by which in her- 
barium work we distinguish Exidia from Tremella, I transfer 
this species to Exidia, as follows:
