The ultraviolet and infrared spectra of some lichen depsides and depsidones

, 1966
The ultraviolet and infrared spectral data for a number of lichen depsides, depsidones and their fission products have been recorded. The U.V. spectra of the orcinol depsides, orcinol depsidones and β-orcinol depsidones are characteristic while those of ...

Functional Traits Mediate Physico‐Chemical Niche Differentiation of Epiphytic Lichens and Bryophytes in Temperate Forests

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Host tree identity drives bark physico‐chemical filters (e.g., pH, metals) that shape epiphytic communities. We show that species‐specific functional traits, such as lichen substances and bryophyte growth forms, mediate these responses. Lichen metal homeostasis and bryophyte growth habit create distinct species thresholds and community change points ...

A Biosynthetic and Taxonomic Atlas of the Global Lichen Holobiont

Environmental Microbiology, Volume 27, Issue 6, June 2025.
This analysis of 794 publicly available lichen shotgun metagenomic datasets, covering 467 unique lichen species from 34 countries, revealed that lichens are complex holobionts. They harbour a variety of fungal, algal, and bacterial players with remarkable biosynthetic capabilities.
