Thallus glaucous, or glaucous green when young, when old 

 or dry ochroleucous ; appressed, deeply and narrowly lacini-

 spadicco-pallescent, rhizinse concolorous or nigrescent, not at

 ■Sn.» margin crenulate especially in immature forms, base of 

 thalline receptacle often nigro-ciliate ; spores '008 — '01 x

 tion Dr, Knight in lit. F.M.B. •'ays — "The Queensland 

 lichen is certainly not P. molliuscula, the thnllus of which
