Abstract
The new species Parmelia brattii Essl. from New Zealand con- tains a new depside, 4-O-methylolivetoric acid, as the principal secondary prod- uct. A second new species P. loxodella Essl., from Australia (including Tas- mania) and New Zealand, has a complex chemistry with glomelliferic acid, glomellic acid and a new compound, loxodellic acid, as the principal constant constituents. Loxodellic acid is proven to be a lower homologue of glomelliferic acid. Chemical structures for the new depsides are based upon evidence from the hydrolysis and thin-layer chromatography of microextracts.
