Coppinsidea vainioana is a species of crustose lichen in the family Ramalinaceae.

Coppinsidea vainioana was originally published posthumously by Finnish lichenologist Edvard August Vainio in 1934 as Lecidea sphaeroidiza, in the fourth volume of his series Lichenographia Fennia.

The type was collected by Vainio in 1882 at Isosaari (Swedish: Mjölö), an island in Helsinki.

The lichen, he noted, was growing abundantly on the bark on pine trees both on the island and also in nearby areas.

[3] However, Vainio's name is illegitimate, because it has an older, competing homonym, Lecidea sphaeroidiza, which was described by William Nylander in 1896.
