Many varieties and forms of this lichen have been recorded ; chief 
among them var. chordalis with proliferous scyphi, recognized by 
Floerke (1. ¢.) as probably a growth form and here included with the 
species; f. abortwa, a rather rare form, has the slender podetia 
terminated and occasionally distorted by the apothecia; f. ceratostelis 
is wholly ascyphous and sterile, a state of the podetia continually 
_ associated with those bearing scyphi. A very slender form, issued by 
Norrlin as subsp. gracillima (Hb. Lich. Fenn. ix. n. 424 (1882); 
Cromb. in Grevillea xi. p. 112 (1883) & Monogr. i. p. 141) has been 
determined by Wainio (Monogr. Clad. Univ. iii. p. 251 (1898)) as a 
modification or growth form with much branched podetia. 
As a rule the podetia of C. gracilis grow in crowded and often 
quite extensive clumps; they are more or less slender and elegant in 
form, about 5-10 cm. long; they tend to become blackish and to die 
off at the base.
