Easily recognized by the frequent central proliferations forming 
up to five tiers of podetia. British forms are rarely fertile.

numerous and crowded, elongate, slender, entirely corticate and 
smooth, simple or br anched, scyphiferous or tapering to a point, 
the scyphi narrow or rarely dilated, forming a rather deep cup 
which is denticulate or proliferous at the margins, pale-greyish 
or -greenish or sometimes brown (K—, CaCl—). Apothecia on 
the tips of the denticulations, rarely sessile on ascyphous 
podetia, brown or reddish ; spores oblong, 9-12 p long, 3-4 p
