“…Recently, Micarea has received more attention and numerous species have been described based on anatomical, morphological and chemical characters and, in some cases, also molecular data (e.g. Czarnota and Guzow-Krzemińska 2010; Svensson and Thor 2011; Cáceres et al 2013; Aptroot and Cáceres 2014; Brand et al 2014; van den Boom and Ertz 2014; Guzow-Krzemińska et al 2016; McCarthy and Elix 2016; van den Boom et al 2017; Kantvilas 2018; Launis et al 2019a, b).…”

Six new Micarea species are described from Europe. Phylogenetic analyses, based on three loci, i.e. mtSSU rDNA, Mcm7 and ITS rDNA and ancestral state reconstructions, were used to evaluate infra-group divisions and the role of secondary metabolites and selected morphological characters on the taxonomy in the M.prasina group. Two main lineages were found within the group. The Micareamicrococca clade consists of twelve species, including the long-known M.micrococca and the newly described M.microsorediata, M.nigra and M.pauli. Within this clade, most species produce methoxymicareic acid, with the exceptions of M.levicula and M.viridileprosa producing gyrophoric acid. The M.prasina clade includes the newly described M.azorica closely related to M.prasina s.str., M.aeruginoprasina sp. nov. and M.isidioprasina sp. nov. The species within this clade are characterised by the production of micareic acid, with the exception of M.herbarum which lacks any detectable substances and M.subviridescens that produces prasinic acid. Based on our reconstructions, it was concluded that the ancestor of the M.prasina group probably had a thallus consisting of goniocysts, which were lost several times during evolution, while isidia and soredia evolved independently at multiple times. Our research supported the view that the ancestor of M.prasina group did not produce any secondary substances, but they were gained independently in different lineages, such as methoxymicareic acid which is restricted to M.micrococca and allied species or micareic acid present in the M.prasina clade.

We present a lichen checklist for the northern shore of the Gulf of Finland in the limits of St. Petersburg, Russia. This area has diverse lichen biota within the city limits, and has been comprehensively studied since 1893, which gives a good base for analysis of historical changes in lichen diversity. The documented lichen biota comprises 469 species (430 lichenized, 24 lichenicolous, 3 facultatively lichenicolous, and 12 non-lichenized saprobic fungi), of them 191 species are known from herbaria and literature for the period before 1991, and 436 species were recorded since 1991 to 2019. Thirty-three taxa were excluded from the lichen list of the study area as erroneous or dubious records. Altogether 48 species are new to St. Petersburg, including: Lecidea malmeana and Micarea czarnotae – new to Russia; Caloplaca lucifuga, Gyalecta nigricans, Micarea soralifera – new to European Russia; Agonimia flabelliformis, Endococcus verrucosus, Lecania turicensis, Micarea fallax, M. tomentosa, Xanthomendoza huculica – new to Northwestern European Russia; Lichenoconium lichenicola, Ramalina europaea, Sarcogyne hypophaea – not known also from the Leningrad Region. The studied lichen biota is moderately rich compared to other city territories. The history of economic development of the region has caused its serious transformation, degradation of natural habitats and therefore partial loss of lichen diversity. At the same time, human-made substrates and anthropogenic plant communities are inhabited by lichens, including species unknown in the natural habitats of the study area. However, 44 species recorded in the study area are red-listed in St. Petersburg, with 13 of them known only from historical collections. Forest communities, as well as historical parks, in NW part of St. Petersburg are important source of biodiversity on regional level nowadays and hopefully in future, and deserve protection.

Thirty-one lichen-forming fungi, 12 lichenicolous fungi, and 5 non-lichenized fungi are reported as new for Arkhangelsk Region; 7 species are new for its mainland area. Micarea fallax is reported for the first time for Russia; M. laeta and M. pusilla are new for the European part of Russia. The second finding of Nicropuncta rugulosa for Russia is recorded; microconidia are first observed in this species. The records of ten species which have been included in the new edition of the Red Data Book of the Arkhangelsk Region (2020) are presented. Nephromopsis laureri from the Red Data Book of the Russian Federation (2008) and Leptogium rivulare from the IUCN Red List are reported for the first time for Arkhangelsk Region.
