The curious case of Cladonia luteoalba: no support for its distinction Lichenologist (IF 1.4) Pub Date : 2022-12-13 Ivana Černajová, Jana Steinová, Zuzana Škvorová, Pavel Škaloud
Cladonia luteoalba shows a specific pattern in chemical variability. Its chemotype coincides with that of the associated Cladonia thalli. This has led to the formation of various hypotheses, but its true nature has never been clarified. We collected C. luteoalba in Central Europe and Norway. The chemotypes were detected by TLC and the mycobionts and photobionts were identified by Sanger sequencing

A hypervolume approach to niche specialism, tested for the old-growth indicator status of calicioids Lichenologist (IF 1.4) Pub Date : 2022-12-13 Christopher J. Ellis
Certain lichen epiphytes are restricted to old-growth forest stands with long ‘ecological continuity’, explained by i) niche specialism and their dependence on microhabitats associated with old stands including veteran or senescent trees, and/or ii) dispersal limitation with probabilities of colonization being relaxed over extended time periods. ‘Calicioid’ species are among the most important old-growth

Peltigera (Lecanoromycetes) on Mt Kilimanjaro, East Africa Lichenologist (IF 1.4) Pub Date : 2022-11-29 Ulla Kaasalainen, Lea Biermann, Neduvoto P. Mollel, Alexander R. Schmidt, Andreas Hemp
Tropical mountain forests are hotspots of biodiversity that are widely threatened by human population pressure and climate change. However, the cryptogamic species richness of many tropical mountain regions is insufficiently known, the poorly understood biodiversity of tropical African lichens being a prime example. To study the diversity of the genus Peltigera (Ascomycota, Lecanoromycetes) in East

Canoparmelia texana (Parmeliaceae, Ascomycota) consists of two independent lineages Lichenologist (IF 1.4) Pub Date : 2022-11-29 Paul M. Kirika, H. Thorsten Lumbsch, Elisa Garrido Huéscar, Taylor S. Quedensley, Pradeep K. Divakar
Recent studies have demonstrated that species boundaries among the lichen-forming fungi are in need of revision with the discovery of cryptic species in numerous clades, especially in parmelioid lichens. Here we focus on addressing the species boundaries in Canoparmelia texana, a sorediate species with a pantropical distribution that extends into temperate regions. We extracted DNA sequences of the
