“…7). Although it is not an aim of this study to resolve the position of the Micarea species within the genus, our molecular tree is very similar in topology to those proposed by Czarnota & Guzow-Krzemińska (2010) and Guzow-Krzemińska et al (2016). Therefore, the occurrence of this species in the Southern Hemisphere is confirmed based on molecular evidence.…”

Fuscidea multispora Flakus, Kukwa & Rodr. Flakus and Malmidea attenboroughii Kukwa, Guzow-Krzemińska, Kosecka, Jabłońska & Flakus are described as new to science based on morphological, chemical and molecular characters. Lepra subventosa var. hypothamnolica is genetically and chemically distinct from L. subventosa var. subventosa and a new name, Lepra pseudosubventosa Kukwa & Guzow-Krzemińska, is proposed due to the existence of Lepra hypothamnolica (Dibben) Lendemer & R.C. Harris. Pertusaria muricata, recently transferred to Lepra, is kept in the genus Pertusaria due to the highest similarity of ITS sequence with members of Pertusaria. The occurrence of Micarea hedlundii in the Southern Hemisphere is confirmed based on molecular evidence from Bolivian population. Lepra pseudosubventosa and Pertusaria muricata are reported as new to South America, and 20 taxa as new to Bolivia. Lepraria stephaniana, previously known only from the type locality, is reported from two more sites. An ascosporic state is reported for the first time for Lepra amaroides, as are new chemotypes. Molecular markers were used to place some sterile, sorediate crustose lichens in the family Graphidaceae. The phylogenetic positions of some sterile Malmidea specimens within Malmidaceae are also discussed.

“…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.

“…has been poorly studied in Asia and especially in the Russian Far East. Recent descriptions of many new species in M. prasina group (Guzow-KrzemińsKa et al, 2016van den Boom et al, 2017;Launis et al, 2019a, b;Launis & myLLys, 2019) inspired us to revise some previous collections and undertake recent field studies on the genus Micarea. Even today in the list of Micarea species known from Asia (a total of ca 30 species), only few have been found exclusively in this large region (aptroot & sparrius, 2003;Kondratyuk et al, 2016a;Konoreva et al, 2018a, b;ohmura & Kaschiwadani, 2018), with very few species described from Asia (KondratyuK et al, 2013).…”

The aim of the study was to consolidate data on lichens of the genus Micarea Fr. from the Russian Far East. A total of 19 Micarea species were found to be known from this area. Micarea laeta and M. microareolata were new to Asia and Russia. Additionally, M. laeta was reported new to North America, Austria and Great Britain, M. microareolata – to North America, Czech Republic and Germany as well. Micarea contexta was reported new to Asia, Micarea adnata and M. tomentosa were reported new to the Russian Far East, M. hedlundii to the South of the Russian Far East and M. lignaria to the Sakhalin Region. Micarea turfosa was excluded from the list. The distribution of taxa and some differences between related species were discussed. Molecular data were obtained and used for phylogenetic analysis of Micarea contexta, M. laeta and M. microareolata.
