Effused, membraiicaceous ; under side villous; circumference 

 byssoid, but not distinctly radiating ; hymenium smooth, bare, 

 pale. Named for me by the Eev. M. J. Berkeley. On decaying 

 wood not uncommon. 



Mycelium and circumference coloured. 



18 C. SANGUiNEUM. Fries Ep. 



Thelephora aurantiaca, E.F. Effused, circumference fibrillose ; 

 hymenopbore loosely adhering to the matrix, which it deeply 

 stains with its own orange crimson colour. On the wood of a 

 fallen branch, Knowsley. 



19 C. ccEEULEUM. Sclirad. 



Effused, sub-orbicular or confluent, sub-tomentose ; bright 

 mdigo-blue, circumference byssoid pale. On fallen branches 

 and sticks, Knowsley. Hangsdales Wood, &c. 



Sub-genus LEIOSTROMA. 



Definitely inferior, uniform, produced by a ivJdte mycelium ivhich 

 soon disappears. 



20 C. CALCEuir. Fries. 



Effused, wax-like, closely adhering to the matrix ; hymeniumi 

 and circumference alike, smooth whitish, much cracked when 

 dry. 



From waxlilce becoming rigid, circumference at first sUghtb/ radiatofioccose, 

 of the same colour as the hymenium, soon quite bare.

Between waxy and membranaceous ; agglutinated ; circum- 

 lorcnce at length free and narrowly involute ; underside 

 blackish ; hymenium flesh coloured. On fallen branches of 

 oak, Knowsley. 



22 C. ciNEREUM. Pers. 



Wax- like, agglutinated, lurid or dusky, pruinose. Firmer, 

 more membranaceous, more easily separated from the matrix 

 and less cracked than Tremella viscosa. On logs and fallen 

 branches. 



23 C. iNCAnNATUM. Fries. 



Effused, membranaceous, rigid, .agglutinated, bright flesh- 

 colour ; margin narrow, pale. This is the description of a 

 plant which I believe to be of the above-named species, but 

 which I have never found except in a barren state. It is not 

 uncommon, especially on dead stems of Ulcx Europaius.
