Hah. On maritime rocks. — Distr. Have in the Channel Islands 

 and S. England. — B. M. I. of Br^chou ; Sark ; Alderney; Jerbom-g,

3. C. myrticola Fee Ess. Crypt, i. p. 63, t. 18, f. 1 (1824). 

 • — Thallus effuse, white or yellowish, somewhat granular or 

 mealy, with scattered raised roundish flat verrucse. Apothecia 

 immersed in the verrucse, black, small, punctiform, angular or 

 flexuose, often confluent, base confluent, blackish-brown ; spores 

 elongate-fusiform, slightly bent, colourless, 2- or 3- (?) septate, 

 0,036-48 mm. long, 0,004 mm. thick. — Leight. Angioc. Lich. 

 p. 25, t. 8, f. 3 ? 



Essentially an inhabitant of southern lands (S. France, &c.). The 

 only specimen in the British Museum is imperfectly developed, and 

 it has been impossible to find spores ; it agrees externally with the 

 diagnosis given for the species. 



Hab. On bark of myrtle and heath. — B. M. Killarney, Kerry. 



4. C. subdiscordans Nyl. in Flora Ixii. p. 221 (1879).— 

 Thallus whitish, thin, granular, continuous, with small roundish 

 verrucse. Apothecia black, aggregate in the verrucse ; hypo- 

 thecium blackish ; paraphyses not distinct, spores oblong-clavate, 

 3-septate, 0,011-16 mm. long, 0,0035 mm. thick, rather thicker 

 upwards ; hymenial gelatine bluish, then sordid-yellow with 

 iodine. — Cromb. in Grevillea viii. p. 29.

97. GLYPHIS Ach. Syn. p. 106 (1816). (PI. 33.) 

 Thallus crustaceous. Algal cells TrentepoJdia. Apothecia 

 immersed in more or less prominent verrucas, roundish or 

 elongate, simple or branched ; apothecial wall well-developed, 

 forming a dark margin ; paraphyses simple ; asci elongate, 4-8- 

 spored, rather thickened at the tips ; spores elongate, pluri- 

 septate, colourless. 



Essentially a tropical genus only sparingly represented in Europe. 

 Owing to the elongate apothecia it is perhaps more characteristically 

 graphideine than the other genera of the order. The spermogonea 

 are unknown. 



1. G. labyrinthica Ach. Syn. p. 107 & in Trans. Linn. 

 Soc. xii. p. 38, t. 2, f. 1 (1818).— Thallus whitish or brownish-
