COCCOCAEPIA,] LECAKO-LECIDF.El. ^»47 



concentrically rugulose towards the circumference, is very rarely partly 

 panniform, and occat^ionally bears pale rliizinae on the under surface. The 

 apothecia are small in proportion to the i^ize of the thallus, though some- 

 times moderate, occasionally having the appearance of being compound, 

 while rarely they are proliferous, with the margin crenate and inflexed. 



Ilab. On the truulcs of old trees, seldom on mossy boulders and walls, 

 in maritime and upland wooded regions. — Distr. Gent-ral and common, 

 especially in the mountainous tracts of Great Britain and Ireland ; scarce

Tar. p. myriocarpa Xyl. Lich, Scand. (1861) p. 128. — Thallus 

 microphylline or grauulose in the centre. Apothecia rather small, 

 numerous, often margined by the granulosa thallus. — Cromb. Lich.

Differs in the smaller, less developed thallus, which is frequently gra- 

 nulose almost throughout, and is thus analogous to var. ^ of Pannaria 

 rubiyinosa. The apothecia are usually crowded, and in a young state are 

 often crowned by gi-eyish thalline gi-anules (form lecanoroidea Ci'omb. 

 Grevillea, xviii. p. 44). 



Hab. On the trunks of old trees in maiitime and upland wooded re- 

 g'wns. —Dif^tr. Rather local in S.W. and N. England, X. Wales, the W. 

 Hi<zhlands, and X.E. Scotland ; rare in the Channel Islands and S. Ireland.

Subtribc II. LECAXOREI Xyl. Flora, 1882, p. 458. 



Thallus squamulose, granulose or pulverulent, internally contain- 

 ing gonidia. Apothecia typically lecanoiiue; spores 8nje, rarely 

 numerous, simple or variously divided ; paraphyses discrete. Sper- 

 mogones usually with jointed sterigmata. 



Well distinguished from the preceding subtribe by the gonidial laver 

 consisting of eugonidia. It is very vaiiable in the characters of the thallus 

 and fructitication, sometimes, in the latter respect, passing as it were into 

 the subtribe eif the Lecideci.
