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. 



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 (/uieo-eWpov, the me- 

 sentery). Gelatinous inclining to cartilag- 

 inous, foliaceous, naked. 



II. CEREBRIN^ (cerebrum, the brain). 

 Firm then pulpy, somewhat pruinose with 

 the spores. 



III. CRUSTACEA (crusta, a crust). Dif- 

 fused, becoming plane. 



IV. TUBERCULIFORMES (tuberculum, a 

 little tuber). Small, somewhat erumpent. 



Tremella. 



XCVI. Tremella mesenterica. 

 Natural size. 



I. MESENTERIFORMES. Gelatinous, inclining to 

 cartilaginous, &c. 



1. T. fimbriata 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.
