Chemical Composition, Antioxidant, and Antimicrobial Activities of Lichen Umbilicaria cylindrica (L.) Delise (Umbilicariaceae)

Evidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012
The phytochemical analysis of methanol and chloroform extracts of Umbilicaria cylindrica was determined by HPLC‐UV method. The predominant phenolic compound in both extracts was depsidone, salazinic acid (1). Besides salazinic acid, the tested extracts of U. cylindrica contain norstictic acid (2), methyl‐β‐orcinol carboxylate (3), ethyl haematommate (4)

The genetic structure of the cosmopolitan three-partner lichenRamalina farinaceaevidences the concerted diversification of symbionts [PDF]

FEMS Microbiology Ecology, 2012
The epiphytic lichen Ramalina farinacea is distributed throughout the northern hemisphere in which the same two algal Trebouxia species (provisionally named TR1 and TR9) coexist in every thallus. Ramalina farinacea symbionts were characterized based on the two fungal nuclear loci (nrITS and rpb2) along with the primary and secondary structures of nrITS

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 ...

Fungal-associated NO is involved in the regulation of oxidative stress during rehydration in lichen symbiosis

BMC Microbiology, 2010
Background Reactive oxygen species (ROS) are normally produced in respiratory and photosynthetic electron chains and their production is enhanced during desiccation/rehydration. Nitric oxide (NO) is a ubiquitous and multifaceted molecule involved in cell

Taxonomic investigation of Abrothallus (Abrothallales, Ascomycota) species associated with lichen genera Ramalina and Bryoria, including the description of a new species

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
The obligately lichenicolous genus Abrothallus consists of approximately 50 species, almost all of which are associated with lichens having foliose, fruticose, or pendulous thalli. This paper focuses on species that grow on strap lichens (Ramalina) providing new insights into their phylogenetic relationships and distribution.

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Copper induced physiological changes and oxidative damage in lichen Ramalina farinacea

Biologija, 2015
Copper is an essential element for all organisms but can reach toxic concentrations as a result of human activities. The aim of the present study was to investigate physiological effects of copper on the lichen Ramalina farinacea  (L.) Ach. The effect of copper on the chlorophyll content, fluorescence and oxidative status was assessed. The chlorophyll

Two Trebouxia algae with different physiological performances are ever‐present in lichen thalli of Ramalina farinacea . Coexistence versus Competition? [PDF]

Environmental Microbiology, 2010
Summary Ramalina farinacea is an epiphytic fruticose lichen that is relatively abundant in areas with Mediterranean, subtropical or temperate climates. Little is known about photobiont diversity in different lichen populations.
