Lecania sordida Reese Næsborg
New to Finland. L. sordida was recently
described by Reese Næsborg (2008). It belongs
to the L. cyrtella group and is characterized by
strongly swollen paraphyse apices. L. sordida
may prefer urban habitats such as graveyards,
tombstones and bricks (Reese Næsborg 2008).
The species was previously known from south
and central Europe, Estonia, Lithuania and
Sweden (Reese Næsborg 2008).

Mycobilimbia pilularis
New to Finland. The species is usually epiphytic,
but may rarely grow on rocks (Santesson et al.
2004).

Parabagliettoa cyanea (A.Massal.) Gueidan &
Cl.Roux
(Syn.: Verrucaria cyanea)
New to Finland. The species is characterized by
small 3/4-immersed perithecia; involucrellum
that covers half or more than half of the exciple;
pale exciple; white to grey endolithic or thinly
epilithic thallus and rather small (15−20 × 6−8
µm) spores (Breuss 2008). The species was
recently transferred from Verrucaria to the new
genus Parabagliettoa (Gueidan et al. 2009). V.
vicinalis Arnold is similar, but has smaller
spores: 12−16 × 5−7 µm (Breuss 2008). V.
glauconephela has thicker thallus and its spores
tend to be slightly smaller than in P. cyanea.
However, further studies are needed to decide if
