Notwithstandiog the specific name, this plant is not nearly so " coral- 

 linoid " as the preceding, from which it is distinguished by the rounded 

 and laxly branched thallus, the shorter branches, and the persistent sub- 

 globose receptacle ot" the apothecia. It occurs in extensive patches, 

 varying in colour from glaucous in shady to brownish or even reddish in 

 exposedhabitatSjthe branches being somewhat shining in the upper portion, 

 and the larger ones more or less indistinctly articulate. The aputhecia 

 are chiefly on the main branches, and remain closed for a considerable 

 time. Our figure (p. 103 j illustiates their structure : a is a section of the 

 thalline receptacle with an apothecium. In the receptacle is an exteinal 

 pale stratum — the C( rte.v. In the apothecium there is (1) the columellar 

 brown /ij/putheciion, which is blackish above; (2) a bluish-white stratum, 

 which is the hymeniion : and (3) a veiy thick external black straumi, 

 which is the maza-cUum. The spermcgones are terminal either on the 

 sterile branches or on the fibiillfe, aLd are similar to those of <S'. com- 

 pressus, though more frequent.
