242 BRITISH DISCOMYCETES. 



Cups J to 1 line broad. 



This excessively common but very pretty British 

 species can be distinguished from L. subtHissima, (Cooke) 

 chiefly by the size of the sporidia. The cups when young 

 are nearly globose, the stem barely visible or quite 

 absent, the mouth is only a minute pore ; when old the 

 cup expands, exposing the yellow disc, but the margin is 

 always entire and upright never recurved. 



Name Calycinus, resembling a calyx. 



Var. Trevelyani. Cooke in " Grevillea," iii. p. 121. 



Distinguished by the larger sporidia (30 35/z long), 

 and by their tendency to become pseudo-uniseptate.
