Corticola, Brisbane (coll. Bailey, No. 86). 



The paraphyses are rendered distinct and separate by K 

 when they show as very fine threads. This lichen seems to 

 play between L. albella and L. galactina. 



ASCIDIUM PROFUNDUM, sp. 710V. 



Thallus albus vel albidus (K — C — ),la3vis rugulosas tenuis; 

 apothecia profude immersa in substrata (cortice), peridio

 sporaB incolores vel pallide lutescentes, fusiformes aut cylin-

 *032 — -045 mm., iodo cegruleo-infuscatee; paraphyses gracili- 

 mas, conferta3. 



Corticola (coll. Bailey, No. 131). 



The paraphyses are rendered distinct and filiform by K. 



This may only be a sub-species, or even a variety of A. 

 depressum (Mnt.) with larger spores, &c.
