Taxonomic recognition of some species-level lineages circumscribed in nominal Rhizoplaca subdiscrepans s. lat. (Lecanoraceae, Ascomycota)

Abstract: Background Rhizoplaca subdiscrepans (Nyl.) R. Sant., a saxicolous, placodioid lichen, is considered to have a worldwide distribution in warm-temperate to boreal-arctic areas in Asia, Europe and North America. However, recent studies have revealed that this species includes five unrecognized species-level lineages—‘subd A, B, C, D and E’. During research focused on the diversity of saxicolous lichens in mountainous areas of southern Poland, some interesting representatives of the genus Rhizoplaca… Show more

“…R. Sant. known from the southern part of Russian Far East (e. g., Kuznetsova et al, 2022), from which it differs by epruinose apothecia, weakly developed marginal lobes, shape of conidia (not observed in our material), and more orange tinge of thallus (McCune, 2017;Szczepańska et al, 2020). Our material generally corresponds to the description, but it contains a fatty acid and cf.…”

“…At the same time, it is necessary to include other evidence, such as chemistry, ecology, geography and morphology, for the proper delimitation of lichenised fungi species ( Hawksworth 1976 ; Dayrat 2005 ; Crespo and Pérez-Ortega 2009 ). Such careful and versatile analysis of distinct phylogenetic lineages may lead to recognising some previously-overlooked characteristics ( Kroken and Taylor 2001 ; del Prado et al 2007 ; Frolov et al 2016 ; Leavitt et al 2016 ; Szczepańska et al 2020 ). In the recent review paper, Lücking et al (2021) proposed a detailed protocol for consistent taxonomy of lichen-forming fungi.…”

“…The adequate annealing temperature was determined using the gradient method. The PCR programme consisted of an initial denaturation at 95 °C for 6 min, according to a previous study ( Szczepańska et al 2020 ), followed by 30 cycles at 95 °C for 30 sec, 51.2 °C for 45 sec, 72 °C for 45 sec, with a final extension at 72 °C for 10 min. While performing PCR, the Veriti Thermal Cycler (Life Technologies, Carlsbad, CA, USA) was used.…”
