Gowardia
''Gowardia'' is a genus of medium-sized, greyish hair lichens in the family Parmeliaceae. It is a circumpolar genus, mainly restricted to arctic-alpine habitats in northern Canada, Europe, and Russia.〔Halonen, P. L. Myllys, S. Velmala, & H. Hyvärinen. 2009. ''Gowardia'' (Parmeliaceae)-a new alectorioid lichen genus with two species. The Bryologist 112(1): 138–146.〕 ==Taxonomy and naming== ''Gowardia'' was previously included within the genus ''Alectoria'', but is now differentiated from this genus on the basis of its chemistry and colour, as well as by molecular phylogenetics.〔 ''Gowardia'' was named after Trevor Goward, a lichenologist in British Columbia, Canada, in recognition of his "remarkable and ongoing work on North American lichens".〔 This genus currently contains two species, ''Gowardia arctica'' and ''Gowardia nigricans''.〔 The species ''G. nigricans'' was previously called ''Alectoria nigricans'' (Ach.) Nyl., while ''G. arctica'' was not differentiated as a species until the creation of this genus.
