Gilbert—Tremellce of Wisconsin. 1149 
Gelatinous, expanded, undulate, white, becoming brownish 
with age and pruinose with the white spores. Spores oblong, 
slightly curved, apiculus at end 12-14/* long and 5-7/* in 
diam. 
The form found in great abundance with us, and which 
answers very well to this description is one of the largest and 
most beautiful of the group. I have found it making a creamy 
white mass covering a log in patches 30 cm. and more in length 
by 10-15 cm. in width and reaching a height of from 3-6 cm.

7. Tremella lutescens Pers. Pig. 8. 
Tremella lutescens Pers. (Syn. p. 622.) 
Tremella mesenteriformis Bull. (Champ, t. 406 Band D.) 
Very soft and gelatinous, lobes crowded, entire, undulately 
gyrose, pale then, yellowish, spores sub-globose 12-16/*, conidia 
1.5-2/* diam. 
Tremella lutescens and mesenterica, are in many instances 
very much alike, but can be distinguished by the fact that mes¬ 
enterica becomes paler as it grows older while lutescens be¬ 
comes more yellowish. Tr. lutescens is not as firm as Tr. 
mesenterica as a usual thing, but specimens may be found of 
lutescens which dry down into quite a firm mass retaining the 
folds to the last. 
Mesenterica is more brainlike in its folds and lutescens more 
mesentery like.

maturity; spores broadly elliptical 6-9/* diameter, conidia
