We present a checklist for Moshchny Island (Leningrad Region, Russia). The documented lichen biota comprises 349 species, including 313 lichens, 30 lichenicolous fungi and 6 non-lichenized saprobic fungi. Endococcus exerrans and Lichenopeltella coppinsii are reported for the first time for Russia; Cercidospora stenotropae, Erythricium aurantiacum, Flavoplaca limonia, Lecidea haerjedalica, and Myriospora myochroa for European Russia; Flavoplaca oasis, Intralichen christiansenii, Nesolechia fusca, and Myriolecis zosterae for North-Western European Russia; and Arthrorhaphis aeruginosa, Calogaya pusilla, and Lecidea auriculata subsp. auriculata are new for Leningrad Region. The studied lichen biota is moderately rich and diverse, but a long history of human activity likely caused its transformation, especially the degradation of forest lichen biota. The most valuable habitats for lichens in Moshchny Island are seashore and dune communities which definitely deserve protection.

“…2009; Westberg et al . 2011). It is probably the largest lichenized group having multi-spored asci with small, simple ascospores, and among the earliest lichenized ascomycete groups to diverge according to phylogenetic dating studies (Prieto & Wedin 2013).…”

“…Since this clade was acknowledged as distinct from Acarospora in a strict sense and accepted to accommodate seven species mainly reported from the Northern Hemisphere (Westberg et al . 2011), only two further species have been added: M. hassei (Herre) K. Knudsen & Arcadia from North America (Knudsen 2011; Arcadia & Knudsen 2012) and M. westbergii K. Knudsen & Bungartz from the Galapagos (Knudsen & Bungartz 2014). Here we describe Myriospora signyensis Purvis, Fdez-Brime, M. Westb.…”

Myriospora signyensis Purvis, Fdez-Brime, M. Westb. & Wedin is described from Signy Island, South Orkney Islands, Antarctica, where it occurs predominantly on quartz mica schist. This represents the first record of the genus for Antarctica. The distinctive interrupted photobiont arrangement places it within the genus Myriospora (formerly known as the ‘Acarospora’ smaragdula group, or Silobia). The new species is characterized by having large, distinctly elevated, sessile apothecia with a prominent margin and a thallus that is usually lobed at the margins and variously orange-red, rust-coloured or brown-pigmented. Molecular phylogenetic analyses inferred with strong support that M. signyensis is closely related to M. scabrida which is similar in having a lobed, imbricate thallus with large and frequently somewhat raised apothecia, but which differs in never being rusty red, by frequently having a larger number of apothecia per areole/squamule and by having a thick and distinctive thalline epinecral layer. Myriospora signyensis is otherwise most similar to M. dilatata but the thallus of M. dilatata is never imbricate-lobate and the ascomata of M. signyensis have larger and more distinctly raised and sessile apothecia. A worldwide key to the 10 species currently recognized in the genus is presented.

“…In 2004, the Fennoscandian checklist included 2414 lichen-forming species (Santesson et al 2004), while the most recent one includes 2538 species (Nordin et al 2017). Although new discoveries of macrolichens are indeed made (e.g., Arvidsson et al 2012, Frödén and Thell 2010, Klepsland 2013, 2016, the main uncharted territory is found within the world of small, crustose lichens (e.g., Arup et al 2014, Ekman 2015, Svensson and Palice 2009, Westberg et al 2011, 2016. Crustose lichens comprise about two thirds of all lichens in Fennoscandia, but the taxonomic status, distribution and ecology of several hundred of these species are virtually unknown.…”
