lu the type of the apothecia this has the same relation to Calicium that 

 Biatora has to Eahcidea. It differs from Calicitim in the pulverulent 

 globo.«e capitulum and in the constantly spherical form of the spores, 

 although, as already observed, it closely approachts subgen. Allodium.

The thallus, which is more or less effuse, and internally has oblongo- 

 cylindrical gonidimla, occasionally becomes nearly evanescent. The sti- 

 pites are very weak, and consequently more or less flexuose ; while in 

 old age thej^ are denudate and become brown or blackish The apothecia 

 when present (for the thallus is very frequently infertile) are numerous, 

 scattered, or crowded. Our fig. {h) shows the brown axis of the stipes 

 ascending into the cupula, left white in the figure, and the pale brownish 

 pulvinate subcolumelliform hypothecium. The spermogones are apt to 

 he overlooked, being nearly coucolorous with the thallus. 



Hab. On the roots of decayed trees and on dead twigs, occasionally on 

 the ground and decayed mosses, rarely on rocks in shady upland places. — 

 Distr. General throughout England, rare in N. Wales, S. and Central
