thick, but the color is more of a fleshy tan (see also under N. ence- 

 phala). This is probably what he later named T. encephala var. Steid- 

 lerii which agrees well with our plant except that he says the color of 

 the plant is brown and the spores hyaline (Ann. Myc. 6:42. 1908). 

 Lloyd thinks our plants are T. mesenterica, but I am satis- 

 fied that it cannot be that species, if indeed that is different from 

 T. lutescens. The genus Naematelia may be taken as based on the 

 species N. encephala and it seems to me that our plant is sufficiently 

 like it to be placed in the same genus. Tremella nucleata Schw., 

 placed in Naematelia by Fries is too different to be cogeneric with the 

 other two, and would proliably just as well be put in the genus Exidia.

4111. Deciduous twig by path north of Piney Prospect, February 13, 1920. Sur- 

 face roughened, the white internal membrane barely showing, not hol- 

 low. Plant old and in part turned nearly white, other part watery 

 orange.

Plates 23, 41 and 56 



Small, pulvinate, nearly even or more often convoluted, flattish or 

 convex or in larger plants pinched up in center; 1-6 mm. in diameter, 

 often crowded into lines which may be up to 1-2 cm. long ; gelatinous, 

 translucent; color quite 'variable, a clear wane color or dull reddish- 

 brown or faded to a pallid watery wiiie or dusky amber or nearly 

 hyaline; not glaucous; the habit \^vy like that of Exidia glandulosa. 

 In the fresh state the whitish, seed-like nuclei may or may not be ap- 

 parent even though they may show up on drying. Not a few plants 

 of a good sized colony show no nuclei even when dry, and such if 

 found alone would be referred to Exidia. The nuclei are irregularly 

 scattered through the plant and are often so small as to be nearly in- 

 visible without a lens. They rarely reach a quarter mm. in diameter. 



Spores (of No. 3959) white, curved-elliptic, 3.7-4.2x7.4-11^. Ba- 

 sidia spherical, 10.5-11 x 11-11. 5;u,. 



Schweinitz's description is misleading, but that this is his plant 

 is not open to doubt. A collection from him in the Schweinitz Her- 

 barium looks just like ours with scattered seed-like nuclei. Under 

 the name of Tremella abida in the Curtis Herbarium are a variety 

 of plants. One of these from England (Broome) is N. nucleata. 

 Another from Massachusetts (Sprague) is a Dacrymyces.
