Summary: The Rostania occultata species complex in Fennoscandia has been revised and found to consist of four species that are all epiphytes on deciduous trees. This study describes two newly discovered species, Rostania effusa and R. pallida, which were found in old-growth boreal coniferous forests and subalpine birch-dominated forests in Fennoscandia.

Summary: Peltigera globulata Miadl. & Magain, a new species in the P. ponojensis/monticola species complex, is described in this study. Although ITS1-HR is not useful for species identification in this complex, gene flow analysis shows no significant level of gene flow among different lineages. Moreover, misclassifications of certain species were also discovered.

Summary: The conservation of epiphytic lichens in managed forest landscapes requires an understanding of their limitations in dispersal and establishment after harvesting. A study in the Kispiox inland temperate rainforest of British Columbia, Canada, found that the colonization of lichens on regenerating spruce trees 25 years after logging was influenced by the distance from the forest edge, surrounding forest age, and opening size. Smaller openings and shorter distances between edges in forests rich in epiphytic lichens can facilitate their recolonization and conservation.

Summary: The ontogeny and taxonomy of dome-headed pachycephalosaurs are controversial, with debate centered around the validity of species within the genus Sphaerotholus. Morphometric, histological, and phylogenetic analysis have been used to address these issues. The data support the validity of both S. edmontonensis and S. buchholtzae, and their placement within the genus Sphaerotholus.

Summary: This study conducted a wide-scale field investigation in the arid and semi-arid regions of Northwest China and discovered seven new taxa of catapyrenioid lichens in Verricariaceae, including one genus and one species newly found in China, one genus new to mainland China, and four new species. These findings enrich our understanding of the high species diversity in Verrucariaceae and the lichen flora of Chinese arid and semi-arid deserts.

Summary: This article presents the list of lichens and lichenicolous fungi determined during the 2019 BLAM excursion to Lungau biosphere reserve, along with their substrates. The high number of detected taxa indicates the significance of Lungau as a refuge for endangered lichen taxa in Europe. New species to Austria and Salzburg province are also reported.

Summary: Two new species of the tropical crustose lichen genus Astrothelium were discovered, characterized by muriform, amyloid ascospores. One species has an olive-green thallus while the other has a light brownish to greenish grey thallus, both producing solitary ascomata with unique features.

Summary: This study applied quantitative Magnetic Resonance Imaging (QMRI) to investigate the storage effects on injured and uninjured Tuber aestivum ascomata in different cooling systems. Results showed that injured ascomata stored in the fan forced fridge experienced faster mass and volume losses, as well as decreased water content and relaxation times. The study demonstrated the effectiveness of QMRI in monitoring the freshness and residual mass of post-harvest truffles without compromising their integrity.

Summary: The study reveals that the diversity of Leptogium in Africa is much higher than previously known, with preliminary data on over 70 putative species, including nine established species previously known from the area and over 60 phylogenetically, morphologically, and/or ecologically defined Operational Taxonomic Units (OTUs).

Summary: This article describes two new species of Astrothelium, namely Astrothelium chulumanense and Astrothelium isidiatum, which are found in the Yungas forest in the Bolivian Andes. Astrothelium chulumanense is characterized by concolorous pseudostromata, partially immersed perithecia with an elevated upper portion covered in orange pigment, fused ostioles, absence of lichexanthone (but thallus UV+ orange-yellow), clear hamathecium, 8-spored asci with amyloid, and large, muriform ascospores with median septa. Astrothelium isidiatum is only known in a sterile state, producing isidia that develop in groups on areoles and resemble soralia when broken off. Both species belong to the Astrothelium s.str. according to the phylogenetic analysis. The production of isidia is reported for the first time in Astrothelium and the family Trypetheliaceae.

Summary: Ground-dwelling lichens play a significant role in carbon and nitrogen cycling, albedo, biodiversity, and biomass in high-latitude ecosystems, yet their biomass has been difficult to accurately assess. A new remote sensing model based on deep neural networks has been developed in this study to predict lichen biomass, providing a powerful tool for ecosystem research and rangeland management.

Summary: Dimorphism is a common feature of tremellalean fungi, with Tremella macrobasidiata and Tremella variae showing an abundant yeast stage in their life cycles associated with Lecanora lichens. The sexual filamentous stage is restricted to specific lichen species for each Tremella, while the yeast stage can be more versatile. This research suggests a wider distribution and abundance of lichen-associated Tremella than previously thought, prompting new questions about their biology and ecology in symbiosis.

Summary: This paper provides an introduction and review of lichenicolous 'heterobasidiomycetes' belonging in the Tremellomycetes and Pucciniomycotina, with a focus on recent studies and novelties of their classification, phylogeny, and evolution. Phylogenetic analyses reveal that the lichenicolous members of Chionosphaera form a monophyletic group in the Pucciniomycotina, leading to the description of the new genus Crittendenia to accommodate these species. Crittendenia, Cyphobasidium, and Lichenozyma are the only lichenicolous lineages known in the Pucciniomycotina.
