B. — Species, quarum thallus extus et medulla hydrate ka- 
lico flavo-tinguntur. 
Thallus externe hoe auxilio chemico flavum sumit colorem, 
at medulla denudata tum modo dilute flaveseit vel vix tingitur 
in: Ph. latifolia (Mey. et Flot.) cum varr. gilactophylla (Tuck.) 
et subromosa Nyl., Ph. erinacea (Ach.). 
Contra thallus totus, extus et medulla, bene favo-tingitur in: 
Ph. lewcomela Mich. et var. angustifolia (Mey. et Flot.), Ph. co- 
mosa (Eschw.), Ph. barbifera Nyl., Ph. speeiosa (Wulf), Ph. obesa

Ph. podocarpa Bel. propria sit species distineta, nam hy- 
drate kalico medulla ejus et pagina infera thalli e flavo mox 
erocee vel croceo-ferruginee tinguntur. In PA. leucomela color 
flavus reactionis kalicae non ita mutatur. 
C. — Species, quarum thallus hydrate kalico flaveseit et me- 
dulla non tingitur. 
Huc pertinet stirps Ph. pietae (Sw.). Ph. aegialita Ach. (Par- 
melia confluens Fr.) parum vel vix ab ea differt.
