disk dark red, margin entire, flexuose, receptacle rough or 

 papillose. Spores 6- — 8, colourless, acicular or elongate- 

 K. fusiform, 3—7 septate, -06— -073 x -003— -004 m m. 



Hab. — On bark near Brisbane, Enoggera, Logan River 

 and Mt. Mistake. 



" Differs from R. crenulata v. stenospora Nyl. in the 

 margin of the apothecia being entire instead of lacero- 

 crenate. R. dichroa has also elongated narrow spores, 

 but the thallus is lurid fuscous beneath, and the whole 

 plant larger and coarser than R. rhaphispora." Dr. 

 Knight in Proc. Roy. Soc. Qd. Vol. I. 



3. R. Hartmanni, J. Muell. 



Thallus closely appressed to the bark below, pale glaucous, 

 surface smooth and shining ; lobation imbricate, irregular,

 recurved, in younger forms the ultimate segments are 

 K. sub-erect and dentate ; under surface pale fawn-colour 

 with dark-brown central tomentum. Apothecia 5 — 7 

 m.m. in diameter ; margin thin, prominent, lobate-crenate; 

 disk blood red, flat, plano-convex or corrugated. Spores

4. R. crenulata, Hook.

 late, and sinuately crenate in the margins ; beneath pallid
