Sagedia mastrucata (Wahlenb.) A. Nordin, Savić & Tibell Mycologia 102: 1346. 2010. ≡ Lichen mastrucatus Wahlenb., Fl. Lapp.: 413. 1812. ≡ Lecanora mastrucata (Wahlenb.) Ach., Syn. Meth. Lich. (Lund): 148. 1814. ≡ Aspicilia mastrucata (Wahlenb.) Th. Fr., Nova Acta Regiae Soc. Sci. Upsal., ser. 3, vol. 3: 234. 1928. (Fig. 1E) Thallus lichenized, crustose, thin to thick, developing as small patches between other lichens, areolate, pale to dark grey, sometimes with greenish tint, matt. Areoles flat to convex, irregular, 0.25–2.0 mm in diam. Prothallus usually indistinct, pale-grey and shiny. Soralia on the surface of the areoles, irregular to rounded, flat to convex, 0.3–1.0 mm in diam., confluent in older parts of the thallus. Soredia greyish-black to greyish-green, usually darker than the thallus. Apothecia and pycnidia not seen in the analysed material. Chemistry: Norstictic acid, sometimes additionally with stictic acids were detected in the Polish specimens, which is consistent with data from the literature (Wirth et al. 2013). Ecology and distribution: Sagedia mastrucata is not a very common species. It has been reported mainly from Europe, including Austria, Finland, France, Germany, Italy, Norway, Portugal, Russia, Spain, Sweden and Switzerland, but also outside of Europe, from Turkey (Vitikainen et al. 1997; Llimona & Hladun 2001; Owe-Larsson et al. 2007; Roux 2012; Wirth et al. 2013; Nimis et al. 2018; Urbanavichus et al. 2020; Westberg et al. 2021; Nimis & Martellos 2022). Here, it is recorded from Poland for the first time, exclusively from the south-west part of the country, where it was found growing on basalt rocks in low mountain areas, under open, well-lit and usually warm and dry habitat conditions. Notes: Sagedia mastrucata belongs to a poorly know complex of soredioid and usually sterile species that also includes S. simoensis (Räsänen) A. Nordin, Savić & Tibell and Aspicilia grisea Arnold. The characteristic features of these taxa are the vegetative structures that develop on the ...
