“…However, it is presently known that morphological characters may not be sufficient for detecting taxa ( Bickford et al, 2007 ; Crespo & Pérez-Ortega, 2009 ). On the other hand, careful morphological analysis of distinct phylogenetic lineages may lead to the recognition of some previously overlooked characters ( Kroken & Taylor, 2001 ; Del Prado et al., 2007 ; McCune & Altermann, 2009 ; Frolov et al, 2016 ).…”

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 were found. The main aim of our study was to determine the taxonomic status of the collected specimens by means of molecular tools and a comparative analysis of similar herbarium materials. Methods Detailed morphological, anatomical and chemical examinations of reference material from Asia, Europe and North and South America focused primarily on a selected group of lecanoroid taxa with a placodioid thallus. In addition, 21 new generated sequences representing Lecanora pseudomellea, Protoparmeliopsis muralis, Rhizoplaca opiniconensis, R. subdiscrepans s. lat. and R. phaedrophthalma were selected for molecular study using the internal transcribed spacer region (ITS rDNA), together with 95 available GenBank sequences mainly from the genus Rhizoplaca. Results Polish specimens that clustered with members of a potential species-level lineage ‘subd E’ of Rhizoplaca subdiscrepans complex were recovered. Comprehensive analyses of the lichen group led us to the conclusion that lineage ‘subd E’ represents R. subdiscrepans s. str. and that the taxon appears to have a limited geographical distribution and specific habitat preferences. Furthermore, some of the recently defined species candidates within R. subdiscrepans s. lat.—‘subd D’ and ‘subd A’—should be assigned to two previously known species of Rhizoplaca, namely R. opiniconensis (Brodo) Leavitt, Zhao Xin & Lumbsch and R. phaedrophthalma (Poelt) Leavitt, Zhao Xin & Lumbsch, respectively. These two species are characterized by phenotypic features observed as well in analyzed specimens representing lineages ’subd D’ and ’subd A’. Moreover, the representatives of these lineages demonstrate some differences in occupied habitat and geographical range that also correspond with the indicated species. Additionally, it was found that Lecanora pseudomellea B.D. Ryan is a strongly supported monophyletic lineage within Rhizoplaca, and therefore an appropriate new combination for the species is proposed.

Caloplaca solis described as a new species from limestone and basic siliceous rocks on the southern and western coasts of Great Britain. It is characterized by a well-developed, crustose, non-placodioid, epilithic, cracked, orange-yellow thallus, almost concolorous apothecia up to 0·66 mm diameter, and ascosporesc. 11·0–12·2–13·0 µm long with a septumc. 0·4×the ascospore length.Caloplaca dalmaticais related but differs in the endolithic or only thinly epilithic thallus.Caloplaca marinais darker orange in colour, with more convex areoles, and is mostly confined to the splash zone of the seashore.Caloplaca maritimadiffers in the typically more convex, sometimes isolated areoles, and often in the presence of a crenulate thalline margin in young apothecia.Caloplaca itianais newly reported from Great Britain from coastal limestone; it differs fromC. solin the thallus being endolithic or almost so, and fromC. dalmaticain the more completely endolithic thallus and the larger ascospores.
