Flavopunctelia praesignis

Flavopunctelia praesignis is a species of foliose lichen in the family Parmeliaceae.

It was first described as Parmelia praesignis by Finnish botanist William Nylander in 1872.

[1] In 1982, Hildur Krog transferred it to the subgenus Flavopunctelia of her newly circumscribed genus Punctelia, created to contain Parmelia species with punctate (point-like) pseudocyphellae.

[2] Mason Hale raised this subgenus to generic status a couple of years later.

In the thalli of partially burned lichens, the bleached portion fell off the tree leaving the green, metabolically active parts of the thallus remaining, thus creating space for recolonization as well as regeneration of remaining fragments.
