I. aleurites I. angustior I. evernica I. placorodia I. pyxiniformis I. sipmanii I. venezolana Imshaugia is a genus of seven species of foliose lichens in the family Parmeliaceae.

In a previous study of Parmeliopsis,[2] Meyer noted a group of species (represented by P. aleurites and P. placorodia) that would be better accommodated in a separate genus.

[6] Imshaugia lichens are foliose with a mineral-grey to whitish-grey thallus and a whitish to light brown lower surface.

[6] The upper cortex is paraplectenchymatous (a cell arrangement where the hyphae are oriented in all directions), measuring 10–20 μm thick, and covered by an epicortex with pores.

[1] The species Imshaugia subarida, proposed by John Elix in 2004 (a new combination from genus Canoparmelia),[8] has since been transferred to Austroparmelina.
