Corticola (coll. Bailey, No. 58). 



In every instance the peridium is obliquely set, and has a 

 longish oblique neck, ending in a minute ostiolum, but here 

 and there 2, or even 3, of these peridia are clustered and 

 apparently enclosed in the same black stroma. Accordingly, 

 this curious lichen has affinities to Trypethelum, but may 

 well constitute the type of a new genus under the name 

 given above. 



Lichens contributed by Mr. Hugh Paton, of Glasgow.
