86 MM. L. R. AND C. TULASNE ON THE TREMELLINEOUS FUNGI 
frequently in germinating they produce secondary spores, after 
the manner of the spores of Tremella violacea Relh. (See the 
Ann. des Se. Nat. 8rd ser. t. xix. pl. 12. fig. 12.) 
Another Corticium, from the same author as the former, the 
Corticium cesium Pers. (Obs. Mycol. part i. p. 15, pl. 3. fig. 6) 
or Thelephora (Phyllacteria) cesia Fr. (Syst. Myc. t. i. p. 449, 
n. 2), presents a very analogous structure. It also is found 
on damp sand in forests; but it is far thinner and more 
brittle, and its dark colour is ash-blue. It does not, as far as we 
have ever seen, invade (like Corticium incrustans) the stocks of 
herbaceous plants and shrubs, or shoot forth from its surface 
any kind of clavules. Its outside is exactly like that of an applied 
or resupinate Thelephora. Nevertheless its hymenium is composed 
of globose basidia, which divide into two, three, or four equal parts, 
which produce afterwards as many linear sterigmata, four or five 
times as long as themselves. The spores of the fungus are just 
like those of Corticium incrustans. 
The two plants of which we are speaking, and which have been 
placed amongst the Thelephore, are evidently very far from their 
natural allies; we propose to unite them to the Tremellineous 
fungi under the generic name of Sebacina. 
Here are, then, two new diagnoses for our mycological cata- 
logues.
