The species is rare on calcareous rocks in Fennoscandia (Fröberg 1989, Santesson et al. 2004). Specimen examined: Varsinais-Suomi: Västanfjärd, Vesterillo, Illogruvan, abandoned lime quarry, open quarry waste field, on stones, 60°01′N, 22°42′E, 24.VII.2008, 33236. 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). Specimens examined: Varsinais-Suomi: Lohja, Paloniemi, Hevossaari island, herb-rich forest, on cement bricks, 60°15′N, 24°01′E, 6.III.2007, 30123; Lohja, Paloniemi, Onkinen SE, island, on concrete foundation, 60°15′N, 24°00′E, 16.III.2007, 30368; Lohja, Ojamo, Ojamo lime quarry, young deciduous forest on quarry waste soil, on stone, 60°14′N, 24°02′E, 23.III.2007, 30444; Lohja, Lohja, 350 m S-SW of Hiidensalmi, deciduous forest, shore bank of lake Lohjanjärvi, old lime quarry waste soil?, on pebbles, 60°15′N, 24°03′E, 28.III.2007, 30574; Karjalohja, Pitkälahti, Kalkkimäennokka, abandoned lime quarry, on quarry waste stone, 60°11′N, 23°46′E, 29.VIII.2008, 33559.

The species is usually epiphytic, but may rarely grow on rocks (Santesson et al. 2004). Specimen examined: Varsinais-Suomi: Lohja, Koski, 200 m W of Varkaanuuninmäki, amphibolite rock, on W-facing wall, scarce, 60°21′N, 24°05′E, 13.V.2008, 32539. 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
20 Juha Pykälä GRAPHIS SCRIPTA 22 (2010) V. glauconephela is a distinct species or if it should be lumped with P. cyanea (Breuss 2008). V. amylacea Hepp (Pykälä & Breuss 2008) has larger (0.25−0.4 mm diam.) and 1/4−1/2immersed perithecia. Specimens examined: Varsinais-Suomi: Vihti, Niuhala, Taka-Moksi, Picea abies-dominated forest, abandoned lime quarry, on W-facing wall, 60°29′N, 24°26′E, 27.IX.2006, 29580. Uusimaa: Vantaa, Hämeenkylä, Långbacka, abandoned lime quarry, on S-facing wall, 60°15′N, 24°07′E, 26.IV.2006, 28430; Sipoo, Martinkylä, Tallbacka, Picea abies-dominated forest, abandoned lime quarry, on overhanging W-facing wall, 60°25′N, 25°12′E, 11.VII.2007, 31340. Porina leptalea New to Finland. P. leptalea is a species of shaded humid habitats. In Sweden it has been found growing on bark on the lower side of a fallen Ulmus glabra (Thor & Hultengren 2001). The present finds are the first from Fennoscandia on siliceous rocks, but elsewhere the species often grows on such rocks. Specimens examined: Varsinais-Suomi: Lohja, Paksalo, S of Synnälä, mica gneiss rock, on strongly overhanging W-facing wall, 60°22′N, 24°06′E, 13.V.2008, 32529. Etelä-Karjala: Miehikkälä, Miehikkälä, Muhikonvuori, rapakivi granite rock, on strongly overhanging E-facing wall, 60°43′N, 27°40′E, 13.IX.2008, 33791. Thelidium aphanes J.Lahm New to Fennoscandia. T. aphanes is close to T. incavatum, but differs in having smaller perithecia (exciple 0.2 vs. 0.3−0.5 mm diam.) (Zschacke 1934). T. aphanes is a rarely collected central European lichen with its nearest site outside Finland in Poland (Faltynowicz 2003). Specimen examined: Varsinais-Suomi: Särkisalo, Förby, Vähämaankaula, flat calcareous rock, on pebbles, 60°05′N, 22°52′E, 23.VII.2008, 33135. Thelidium papulare New to Finland. Descriptions of the species differ moderately between different sources. The specimens fit with the description of T. papulare by Orange (1992) and Thüs & Nascimbene (2008). Specimens examined: Etelä-Häme: Korpilahti, Korospohja, Vaarunvuori, high amphibolite rock, cliff, on S-facing wall, 61°55′N, 25°42′E, 12.VIII.2007, 31807. Varsinais-Suomi: Karjalohja, Maila, Ämmänuuninkallio, calcareous rock on shore of lake Lohjanjärvi, on NW-facing wall, 60°14′N, 23°49′E, 16.IX.2008, 33931, 33934. Thelidium rimosulum M.Ceynowa-Giełdon New to Fennoscandia. Description based on the Finnish specimen: thallus epilithic, brown and isidiate; perithecia 0.2−0.25(−0.3) mm diam., 1/2−3/4-immersed; involucrellum extending to the middle or to the base of the exciple; exciple dark; spores 1-septate, 17−21(−23) × 5−8 µm. The species was recently described from Poland by Ceynowa-Giełdon (2007). T. rimosulum is characterized by frequent occurrence of isidia and/or soredia. Soredia were not found from the Finnish specimen. The Finnish specimen differs from the type material by the length of the spores being (11−)13−17(−19) × 5−7(−8) µm in the type material (Ceynowa-Giełdon 2007). Specimen examined: Varsinais-Suomi: Lohja, Ojamo, Ojamo lime quarry, semi-open quarry waste field, on pebbles, 60°14′N, 24°02′E, 15.IV.2006, 28314. Verrucaria apatela (A.Massal.) Trevis. New to Fennoscandia. Description based on the Finnish specimen: thallus thick, areolate and medium to dark brown; areoles 0.3−0.5 mm diam.; perithecia 0.2−0.25 mm diam., immersed; exciple 0.2−0.25 mm diam., dark; involucrellum, thick, extending to the base of the perithecia; spores 23−28(−31) × 11−14(−15) µm. V. apatela belongs to the V. macrostoma–group, which is
