With rare exceptions, the shape and appearance of lichen thalli are determined by the fungal partner; thus, mycobiont identity is normally used for lichen identification. However, it has repeatedly been shown in recent decades that phenotypic data often does not correspond with fungal gene evolution. Here, we report such a case in a three-species complex of red-fruited Cladonia lichens, two of which clearly differ morphologically, chemically, ecologically and in distribution range. We analysed 64 … Read more... 

Microcalicium loraasii is described as new to science from old-growth boreal forest in Grane municipality, Northern Norway. It is characterized by its sessile to short stalked, cylindrical ascomata with a greyish white pruina, non-protruding mazaedium and 0–4-septate ascospores. Maximum Likelihood and Bayesian Inference phylogenetic analyses of mtSSU, nrLSU and nrITS sequence data confirm its placement in Microcalicium. The species is so far only known from the type locality where it was … Read more... 

Aim: Functional traits offer a window into how organisms are adapted, and might acclimate, to environmental pressures. Despite being important in ecosystem function, lichens are underrepresented in trait-based research; understanding how lichen functional traits vary with climate and habitat availability will be useful in predicting how communities will respond to climate change, for example, in wetter and warmer boreal and arctic ecosystems. Here, we assess the influence of macroclimate … Read more... 

[in Ukrainian with English abstract: ] The article presents data on the study of lichen biota in the city of Beregovo (Zakarpattia region). Totaly, 84 species of lichens and 13 species of lichenicolous fungi were identified. Among them Bryostigma phaeophysciae, Epiphloea byssina, Heterocephalacria physciacearum, Laetisaria lichenicola, Lichenochora obscuroides, Stigmidium fuscatae, Xanthomendoza huculica are reported for the first time to the Zakarpattia region. Calogaya decipiens, Candelariella … Read more... 

Key message: In order to preserve the continuity of epiphytic and epixylic cryptogamic flora, two things are essential: maintaining the near-natural character of a forest community in relation to the montane zonation and more sustainable forest management in relation to deadwood. Context: Lichens and bryophytes are common species that inhabit dead wood. The relationship between their habitat requirements, which can be expressed by their Ellenberg indicator values and the characteristics of dead logs, … Read more...
