Lebreton E., Ertz D., Lücking R., Simon A., Smith C. & Sérusiaux E. (2024): Further expansion of morphological variability in the Porinaceae (Ascomycota, Ostropales) with the placement of the enigmatic genus Gallaicolichen - The Lichenologist, 56(2-3): 61-71

The foliicolous lichen Gallaicolichen pacificus exhibits unique goniocystangia-like structures named peltidiangia and peltidia. Its taxonomic classification within the Ascomycota has been unclear due to the absence of ascomata and lack of molecular data. Here we clarify the phylogenetic affinities of Gallaicolichen pacificus by analyzing mitochondrial small subunit ribosomal RNA (mtSSU) sequences obtained from specimens collected in New Caledonia. Ascomata and ascospores of G. pacificus, previously … URL EndNote PDF Read more...

Adhikari R., Ngangom R., Ingle K.K., Joseph S. & Nayaka S. (2024): New species and additional records in the lichen genus Malmidea from India - The Lichenologist, 56(2-3): 47-59

A detailed examination of Malmidea specimens deposited in the herbarium LWG and freshly collected samples resulted in the description of 10 new species. Malmidea glabromarginata has a finely verrucose thallus and granifera-type whitish apothecial margins. Malmidea globosa is characterized by having a strongly verrucose thallus with almost spherical warts and piperis-type apothecial margins. Malmidea incrassatispora has a thalline excipulum and ascospores with end wall thickenings. Malmidea kalbii … URL EndNote PDF Read more...

Vijayakumar V.R., Rajendran P.J., Poornimaa M․, Ramanathan K․, Saha T., Das S. & Dharumadurai D. (2024): Structural geometry, electronic properties and pre-clinical evaluation of antibacterial compounds from lichen-associated Streptomyces mobaraensis DRM1 and Nocardiopsis synnemataformans DRM2 - Journal of Molecular Structure, 1312: 138561 [10 p.]

Antibacterial compounds Phenol, 2,4-bis(1,1-dimethylethyl) and Lupeol obtained from lichen-associated Streptomyces mobaraensis DRM1 and Nocardiopsis synnemataformans DRM2 respectively. The geometry, electronic properties and binding affinities of antibacterial compound Phenol, 2,4-bis(1,1-dimethylethyl) and Lupeol was determined. The in silico molecular mechanics of bacterial growth inhibition by Phenol, 2,4-bis(1,1-dimethylethyl) and Lupeol was established in Pseudomonas aeroginosa and Salmonella … URL EndNote Read more...

Saikia P., Borah D., Debnath R., Gogoi D., Goswami K.J., Rout J., Ghosh N.N. & Bhattacharjee C.R. (2024): Green sustainable synthesis of Ag doped SnO2 decorated reduced graphene oxide hierarchical nanohybrid material: An excellent mesoporous catalyst for efficient reduction of nitroaromatics - Journal of Environmental Chemical Engineering, 12(4): 113137 [17 p.]

A foliose lichen species, Lobaria retigera mediated environmentally sustainable, economically viable green synthesis procedure to access Ag doped SnO2 (Ag@SnO2) and hierarchical Ag doped SnO2 decorated reduced graphene oxide (rGO-Ag@SnO2) nanohybrid material is reported. Carbohydrate, a primary metabolite present in the aqueous lichen extract is presumed to be responsible for the reduction and stabilization of the nanoparticles. The nanoparticles were mostly spherical with brid material. The reduction … URL EndNote Read more...

Chen R., Yin B., Yang W., Li J., Li Z., Zhang Y. & Chen J. (2024): Mapping the successional stages of biological soil crusts at 3-m resolution in the Gurbantunggut Desert, China through hydration-induced spectral response - Remote Sensing of Environment, 310: 114230 [16 p.]

Biological soil crusts (biocrusts) are essential components of desert ecosystems and provide diverse ecological services that benefit both the environment and human society. Biocrusts exhibit varying ecological functions as they pass through several successional stages—cyanobacteria, lichens, semi-mosses, and mosses. Remote sensing has been widely applied to monitor the spatial and temporal distributions of biocrusts. However, previous efforts have focused primarily on identifying biocrusts while … URL EndNote Read more...

Cometto A., Ametrano C.G., De Carolis R., Leavitt S.D., Grube M., Pallavicini A. & Muggia L. (2024): Highly heterogeneous mycobiota shape fungal diversity in two globally distributed lichens - Fungal Ecology, 69: 101331 [15 p.]

Lichens are multi-kingdom symbioses in which fungi, algae and bacteria interact to develop a stable selection unit. In addition to the mycobiont forming the symbiosis, fungal communities associated with lichens represent the lichen mycobiota. Because lichen mycobiota diversity is still largely unknown, we aimed to characterize it in two cosmopolitan lichens, Rhizoplaca melanophthalma and Tephromela atra. The mycobiota were investigated across a broad distribution using both a culture-dependent approach … URL EndNote Read more...

Loureiro L., Morais J., Silva R., Martins J.T., Geada P., Vasconcelos V. & Vicente A.A. (2024): Isolation and identification of lichen photobionts collected from different environments in north of Portugal and evaluation of bioactivities of their extracts - Foods, 13(11): 1759 [18 p.]

Lichens are organisms constituted by a symbiotic relationship between a fungus (mycobiont) and a photoautotrophic partner (photobiont). Lichens produce several bioactive compounds; however, the biotechnological exploitation of this organism is hampered by its slow growth. To start studying the possibility of exploiting lichens as alternative sources of bioactive compounds, eighteen lichens were collected in the north of Portugal in order to isolate and study the bioactivity of their photobionts. … URL EndNote PDF Read more...

Zhang Y., Wang W., Wang Y., Zhong C. & Hu L. (2024): Rhizocarpon sichuanense, a new species from Southwest China - Guihaia, 44(4): 635–645

In this paper, we study in Rhizocarpon Ramond ex DC. species by the method of combining phenotypic characteristics (morphology, anatomy and chemistry) with genotypic characteristics (ITS sequence). The aims of this present paper are to clarify the status of some species and explore the relationship between phenotype and genotype in Rhizocarpon. During the study on Rhizocarpon species from southwest China, R. sichuanense Y. M. Zhang, L. Hu & W. C. Wang sp. nov. is described as a new species in this … URL EndNote PDF Read more...

Based on morphological, anatomical, chemical and molecular systematic methods, a taxonomic study was carried out on the lichen genus Phaeophyscia collected from Mount Tai. One species, P. taishanensis is reported as new to science. It is characterized by the following characters: white or hyaline cortical hairs sparsely on the upper surface of the marginal peripheral zones of the lobes; white medulla; black lower surface with sometimes white or pale brown ends; sparse cortical hairs occasionally … URL EndNote PDF Read more...
