I furnish my own description of this form, not having seen any 
other. Thallus similar to type, lirellz short, mostly simple, a few 
branched at right-angles ; thalline margin somewhat prominent ; 
epithecium not furrowed, rimzform, open; proper margin moderate, 
slightly flexuose. I submitted a specimen to Dr. Nylander, who 
named this form as above ; but the Rev. Mr. Crombie claimed to 
have discovered and named it previously.
