COCCOCARPIA. | LECANO-LECIDEEL. 347 
concentrically rugulose towards the circumference, is very rarely partly 
panniform, and occasionally bears pale rhizine on the under surface. The 
apothecia are small in proportion to the size 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.

Var. 3. myriocarpa Nyl. Lich. Scand. (1861) p. 128.—Thallus 
microphylline or granulose in the centre. Apothecia rather small, 
numerous, often margined by the granulose thallus.—Cromb. Lich.

Differs in the smaller, less developed thallus, which is frequently gra- 
nulose almost throughout, and is thus analogous to var. 8 of Pannaria 
rubiginosa. The apothecia are usually crowded, and ina young state are 
often crowned by greyish thalline granules (form lecanoroidea Cromb. 
Grevillea, xviii. p. 44). 
Hab, On the trunks of old trees in maritime and upland wooded re- 
ions.—Distr. Rather local in 8.W. and N. England, N. Wales, the W. 
Highlands, and N.E. Scotland ; rare in the Channel Islands and S. Ireland.

Subtribe II. LECANORET Ny)l. Flora, 1882, p. 458. 
Thallus squamulose, granulose or pulverulent, internally contain- 
ing gonidia, Apothecia typically lecanorine; spores 8ne, rarely 
numerous, simple or variously divided; paraphyses discrete. Sper- 
mogones usually with jointed sterigmata, 
Well distinguished from the preceding subtribe by the gonidial layer 
consisting of eugonidia. It is very variable in the characters of the thallus 
and fructification, sometimes, in the latter respect, passing as it were into 
the subtribe of the Lecidcei.
