N. peltigericola N. medoborensis Norrlinia is a genus of two species of fungi in the family Verrucariaceae.

[1] The genus was circumscribed by Ferdinand Theissen and Hans Sydow in 1918.

[2] The genus name honours the Finnish botanist Johan Petter Norrlin.

[3] Both species are lichenicolous, meaning they parasitise lichens.

The host of both fungi is the foliose genus Peltigera.
