A new species of Lecidea (Lecanorales, Ascomycota) from Pakistan [PDF]

MycoKeys, 2018
We describe here a new species, Lecidea aptrootii, in Lecidea sensu stricto from Swat Valley, Pakistan. It is most similar to L. fuscoatra in having an areolate thallus and black, lecideine apothecia with a persistent margin. However, L. aptrootii can be

The Conjugates of Phenolic Acids in Lichens of the Order Lecanorales

International Journal of Secondary Metabolite, 2014
Lichens are symbiotic associations of a fungus (usually an ascomycete) and a photobiont, which may be an alga and/or a cyanobacterium. Lichens dominate on about 6–8% of land surface, mainly in the habitats with severe climatic conditions.

Deciphering the biosynthetic pathways of lichen acids. [PDF]

New Phytol
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Canopy Height and Epiphytic Bryophytes Shape Fungal Communities in a Temperate Rainforest. [PDF]

Ecol Evol
We present the first investigation into epiphytic bryophyte‐associated microbes in a temperate ecosystem. Our field study reveals taxonomic and functional differences between ground‐ and canopy‐associated fungi. Host plant specificity and bryophyte senescence drive fungal diversity and community composition, indicating strong biotic drivers for fungal ...

Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome. [PDF]

Environ Microbiol
Multi‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...

Chromosome-level genome assembly of the photobiont microalga Trebouxia sp. 'A48' from the lichen Xanthoria parietina. [PDF]

New Phytol
Summary Lichens are symbiotic assemblies consisting of multiple organisms, chiefly a fungus and a photosynthetic microorganism, or photobiont. Among diverse photobionts, the most prevalent is the chlorophyte alga Trebouxia. We produced a chromosome‐level assembly of Trebouxia sp. ‘A48’, a photobiont of Xanthoria parietina. The genome was assembled into

Hidden in the dark under umbrellas: two new Psilolechia species (lichenized Ascomycota , Lecanorales ) described from the Czech Republic

Plant and Fungal Systematics, 2023
Recent lichenological fieldwork in the Czech Republic resulted in the discovery of two previously unrecognized entities in the genus Psilolechia which are described below as new species: the saxicolous P. cretacea and the lignicolous P. torii . Both

Jejulea byssolomoides gen. et sp. nov., a Remarkable Pilocarpaceae (Lichen-Forming Ascomycetes) from Jeju Island, South Korea

Mycobiology, 2022
The new genus and species, Jejulea byssolomoides, is described from Jeju Island, Korea. This lichen is characterized by saxicolous, crustose, pale greenish-gray, partly finely filamentous, matt, smooth thallus, prominent convex brown to dark brown ...

Three new lichen species from Macaronesia belonging in Ramalinaceae , with the description of a new genus

Plant and Fungal Systematics, 2020
Tylocliostomum is described as a new genus and T. viridifarinosum as a new species. Two Bacidina species, B. pallidocarpa and B. violacea , are also described as new to science. They all occur in Macaronesia (Azores, Madeira).
