Zhang Y., Wang L., Wang X., Printzen C., Timdal E. & Wang L. (2023): Squamarina subcetrarioides comb. & stat. nov. (Stereocaulaceae), a separate species from the type species of Squamarina - The Lichenologist, 55(3-4):133-137

The type species of Squamarina has two varieties, S. gypsacea var. gypsacea and S. gypsacea var. subcetrarioides. In this study, a phylogenetic and taxonomic analysis of these two varieties shows that S. var. subcetrarioides merits treatment as a species separate from S. gypsacea. Therefore, we raise this variety to species level as S. subcetrarioides (Zahlbr.) Y. Y. Zhang. Squamarina subcetrarioides is phylogenetically not closely related to S. gypsacea and differs from that species in the thallus … URL EndNote PDF Read more...

Usman M., Firdous Q., Dyer P.S. & Khalid A.N. (2023): A new species of the genus Anamylopsora (Baeomycetaceae; Ascomycota) from Deosai National Park, Gilgit-Baltistan, Pakistan - The Lichenologist, 55(3-4):125-132

A novel lichen species occurring on rocks was collected from three different localities within Deosai National Park, Gilgit-Baltistan, Pakistan. Phylogenetic analyses of the nrDNA ITS and nuLSU regions revealed that it clustered within the genus Anamylopsora. Further chemical and morpho-anatomical analyses confirmed its uniqueness, and it is described here as a new species under the name A. pakistanica. The distinguishing characters are: an irregularly squamulose appressed thallus on rocks without … URL EndNote PDF Read more...

Li L., Wang L. & Printzen C. (2023): A new species and new combination of Lecanora s. str. (Lecanoraceae) from China - The Lichenologist, 55(3-4):115-124

A new lichen species, Lecanora zeorina Li J. Li & Printzen is described here from the south-west of China. Lecanora zeorina is characterized by its somewhat areolate-squamulose thallus, zeorine to lecanorine apothecia, an epihymenium without crystals around expanded paraphyses tips, an amphithecium with large calcium oxalate crystals and the production of atranorin. A new combination, Lecanora crystalliniformis (B.G. Lee & Hur) Li J. Li & Printzen, is based on Protoparmeliopsis crystalliniformis … URL EndNote PDF Read more...

Arup U., Holien H. & Coppins B.J. (2023): Lecanora caledonica – a new species in the Lecanora intumescens group (Lecanoraceae) from north-western Europe - The Lichenologist, 55(3-4):107-114

Lecanora caledonica is described as new to science. Molecular analyses show that it belongs to the L. intumescens group. It is also rather similar in appearance to L. intumescens, but differs mainly chemically in containing only atranorin and an unknown UV+ ice blue substance. There are also anatomical and morphological differences to the other species of the group. The new species has a pronounced oceanic distribution and is so far known only from western Norway and Scotland. corticolous, DNA, Lecanora … URL EndNote PDF Read more...

Honegger R. (1985): Ascus structure and ascospore formation in the lichen-forming Chaenotheca chrysocephala (Caliciales) - Sydowia, 38: 146–157

In the thin-walled pre-meiotic asci of Chaenotheca chrysocephala a peripheral ascospore delimiting membrane cylinder was formed by transformation of membrane material generated by the proliferating plasma membrane. The ascus wall broke in parts and was degraded soon after the onset of secondary ascospore wall formation. Numerous lysosomes were observed prior to ascus deliquescence. The ascospores grew and their secondary wall layer became melanized after their release into the mazaedium. URL EndNote Read more...

Morales-Sánchez J.Á., Mark K., Talts E., Rasulov B. & Niinemets Ü. (2023): Improved monitoring of cryptogam gas-exchange and volatile emissions during desiccation-rehydration cycles with a within-chamber hydration method - Plant Science, 333: 111745 [14 p.]

Desiccation-rehydration studies in cryptogams constitute an important tool to understand the relation of key physiological traits with species stress tolerance and environmental adaptability. Real-time monitoring of responses has been limited by the design of commercial or custom measuring cuvettes and difficulties in experimental manipulation. We developed a within-chamber rehydration method that allows to rewater the samples rapidly, without the need to open the chamber and take out the sample … URL EndNote PDF Read more...

Manninen S., Jääskeläinen K., Stephens A., Iwanicka A., Tang S. & van Dijk N. (2023): NH3 concentrations below the current critical level affect the epiphytic macrolichen communities – Evidence from a Northern European City - Science of the Total Environment, 877: 162877 [11 p.]

Acidophytic, oligotrophic lichens on tree trunks are widely considered to be the most sensitive biota to elevated concentrations of atmospheric ammonia (NH3). We studied the relationships between measured NH3 concentrations and the composition of macrolichen communities on the acidic bark of Pinus sylvestris and Quercus robur and the base-rich bark of Acer platanoides and Ulmus glabra at ten roadside and ten non-roadside sites in Helsinki, Finland. NH3 and nitrogen dioxide (NO2) concentrations were … URL EndNote PDF Read more...
