CONIOCTBE.] CALICIEI. 99 



In the type of the apotliecia this has the same relation to Calicium that 

 Biatora has to Eulecidca. It differs from Calicium in the pulverulent 

 globose capitulum and in the constantly spherical form of the spores, 

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

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

 cylindrical gonidimia, occasionally becomes nearly evanescent. The sti- 

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

 old age they 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. (ft) show's 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 

 be overlooked, being nearly concolorous with the thallus. 



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

 the ground and decayed moss'es, rarely on rocks in shady upland places. 

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

 Scotland, rare in E. Ireland (near Belfast). B. M. : Near Bury, Suffolk ;
