i. v. hypoleuca — Marginal cilia black and with black rhizinae 

 below, thalline margins of apothecia crenulate. 



ii. v. angustilobia — Resembles v. dactyliza in its very narrow 

 lacini«, apothecia much as in v. hypoleuca. 



Hab. — The type is common on the coast but seldom fertile ; 

 the two varieties are found in the ranges, (i.) at Helidon and 

 Mt. Mistake, (ii.) at Toowoomba and Mt. Mistake. 



**** Lacinise short or obscure. 



11. P. picta, Sw. 



Thallus orbicular, horizontal, crustaceous-foliaceous, difficult 

 to detach ; at first with close, appressed, contiguous lacinise, 

 then so closely approximating as to appear merely crusta- 

 ceous ; margins always, if shortly, crenate-incised, not 

 ciliate ; upper surface pallid or pale-glaucous, in young forms 

 Sn. greenish ; central area often coated with white, warty, 

 sorediferous heaps ; beneath nude, black, dull, but whitish 

 at the margins ; apothecia elevate ; disk fuscous ; margin 

 crenulate ; spores brown, 1-septate, oval, *015 — *021 x '005 

 — 007 m.m 



Syn. — Parmelia applanata Fee, P. plumosa TayL, P. leuco- 

 thrix, Tayl. 



The soredioid form is perhaps the same as Physcia melano- 

 clina. C. K. 



Hab.-— Common on shady rocks and trees. 



l'J. P. glauco-virescens, NyL (Medulla K — C — ). 



Thallus cinereo-glauco-virescent, firm, appressed, shortly 

 laciniate, lacinias sub-stellate or sub-imbricate appressed, 

 effuse ; with undulate margins and apices finely areolate

 or whitish, with black fibrils which are not crowded. Nyl. 

 Syn. Lich. p. 419, Vol. I. Apothecia raised ; receptacle 

 thick, tumid ; margin entire or finely crenulate, slightly 

 incurved, disk cassio-pruinose, dark brown ; spores broadly
