3. Tremella frondosa Pr. 



Plates 39 and 56 



This is miic'li the largest of our Tremellas, forming a mass up to 

 15 cm. in diameter, and np to 7-10 cm. high of flat, very thin, crumpled 

 and contorted, petal-like lobes of a gelatinous but quite tough con- 

 sistency like rubber ; fused below into flattened and more or less exten- 

 sive base which enters the wood. Surface quite smooth and, unless 

 old, glaucous with the spores ; color when fresh and not too old a 

 rather light fleshy brown, in age becoming darker ; drying to a raisin 

 color if fresh, or to blackish if old. In drying there is much less 

 shrinkage than in other species and the form is well retained. 



Spores (of No. 4173) white, smooth, spherical to short oval. 

 5.5-7.7 X 6-10. 5/x, a few 8.5/x wide. Basidia pear shaped, irregularly 

 divided into four cells, 7.7-9.3 x 11-15/^, some up to 18ix. 



Edible. Our nearest relative of this is T. aspera which may ap- 

 proximate it in size and color. For easily distinctive marks see under 

 that species. Bulliard's PI. 499, fig. 6T is good of the plant, so also 

 is Lloyd's fig. 1195 in Mye. Notes 55. 1918. Brefeld gives the spores 

 of this species as spherical with a mucro, 10-12/j, (I.e. p. 122). Under 

 the name T. foliacea in the Curtis Herbarium are most of the large 

 leafy Tremellas, some of which are certainly T. frondosa. The differ- 

 ence between these two species, if any, docs not seem to be well 

 established. See Gilbert's illustrations in Trans. Wis. Acad. 16: PI.

4. Tremella aspera n. sp. 



Plates 40 and 56 



A good-sized plant, in our one collection about 3-5 cm. long, 2-3 cm. 

 broad and 3-4 cm. thick, formed of flattened, much crumpled and con- 

 torted lobes which arise from more or less extensive and separated 

 points of attachment ; surface not smooth, but finely granular under a
