ORDER VI— TREMELLINEI. 



Whole fungus homogeneous, gelatinous, shrivelling when dry, 

 reviving when moistened, pervaded internally with branched 

 filaments, terminating towards the surface all round in sporo- 

 phores ; spores somewhat reniform. 



The structure of the Tremellini is admirably illustrated by 

 Tulasne in Ann. Sc. Nat. 1853. Fr. Hym. Eur. p. 689. 



Genus LVII. — Tremella {tremo, to tremble). 

 Dill. — Fr. Syst. Myc. 2. p. 210. 



Tremella. 



Distended with jelly when moist, 

 tremulous, immarginate, not papil- 

 late, sporophores globose, becoming 

 quadripartite, and sending out from 

 each division an elongated free spi- 

 cule, which terminates in a simple 

 spore. Fr. Hym. Eur. p. 689. 



I. Mesenteriformes (jaeo-eVrepov, the me- 

 sentery). Gelatinous inclining to cartilag- 

 inous, foliaceous, naked. 



II. Cerebrin^e (cerebrum, the brain). 

 Firm then pulpy, somewhat pruinose with 

 the spores. 



III. Crustacea {crusta, a crust). Dif- 

 fused, becoming plane. 



IV. Tuberculiformes (tuberczdum, a 

 little tuber). Small, somewhat erumpent. 



XCVI. Tremella mescnterica. 

 Natural size. 



I. — Mesenteriformes. Gelatinous, inclining to 

 cartilaginous, &c. 



1. T. fimhriata Pers. — Olivaceous inclining to black, casspitose, 

 clusters 5-7.5 cent. (2-3 in.) high and even broader, erect, corru- 

 gated] lobes flaccid, incised at the margin, undulato-fimbriate.
