Aptroot A., Cáceres M.E.d.S. & Santos L.A.d. (2024): The taxonomy of sterile Arthoniaceae from Brazil: white crusts on overhanging tropical trees can be named - The Lichenologist, 56(1): 1-13

Twelve new lichen species are described in the family Arthoniaceae. All are sterile white crusts growing on overhanging trees (and one on living palm fronds) in ten different states in tropical Brazil. In the tropics, sterile crusts so far have been mostly disregarded. They are all characterized by their chemistry and morphology, often including pseudoisidia or soredia, but their phylogenetic relationships have been investigated with sequencing. The following species are described: Arthonia farinosorediata, … URL EndNote PDF Read more...

Boluda C.G. & Kitara N.N. (2024): Placopsis craterifera (Trapeliaceae, Lecanoromycetes), a new lichen species from alpine habitats on Mount Meru, Tanzania - The Lichenologist, 56(1): 15-20

During a field trip to the highlands of Mount Meru in Tanzania, two Placopsis specimens were collected. Morphological analyses showed a unique combination of characters not observed in any other published taxa within the genus. The specimens are characterized by their circular soralia, not confluent, crater-shaped, with a prominent white margin and coarse granular pinkish central soredia. Considering the morphological, geographical and genetic data, we propose the designation of a new species, Placopsis … URL EndNote PDF Read more...

Goss A. & Werth S. (2024): New microsatellite loci to quantify genetic diversity of the photosymbiodeme-forming lichen Sticta canariensis - The Lichenologist, 56(1): 39-45

Sticta canariensis is a lichen which is rare in all parts of its range in Atlantic Europe and Macaronesia, where it occurs in laurisilva forests, a habitat highly threatened by global change. Thus, this species is of high priority for inclusion in conservation programmes where genetic diversity should be considered. We have established new microsatellite loci and generated a dataset that demonstrates the genetic diversity of the lichen-forming fungus S. canariensis from eight locations across its … URL EndNote PDF Read more...

Kantvilas G. (2024): Additions to the genus Cliostomum (Ramalinaceae) from Australia - The Lichenologist, 56(1): 27-37

Seven species of Cliostomum Fr. recorded from Australia are treated. These include the widespread C. griffithii (Sm.) Coppins, the austral C. praepallidum (Müll. Arg.) Kantvilas & Fryday and the Tasmanian endemic C. vezdae Kantvilas, a reinstated name previously subsumed under C. flavidulum Hafellner & Kalb. Three species are described as new: C. latisporum Kantvilas, a corticolous species containing atranorin and gangaleoidin from coastal Tasmania and New South Wales, characterized by pale pink, … URL EndNote PDF Read more...

Tejada-Purizaca T.R., Garcia-Chevesich P.A., Ticona-Quea J., Martínez G., Martínez K., Morales-Paredes L., Romero-Mariscal G., Arenazas-Rodríguez A., Vanzin G., Sharp J.O. & McCray J.E. (2024): Heavy metal bioaccumulation in Peruvian food and medicinal products - Foods, 13(5): 762 [35 p.]

To better query regional sources of metal(loid) exposure in an under-communicated region, available scientific literature from 50 national universities (undergraduate and graduate theses and dissertations), peer-reviewed journals, and reports published in Spanish and English were synthesized with a focus on metal(loid) bioaccumulation in Peruvian food and medicinal products utilized locally. The study considered 16 metal(loid)s that are known to exert toxic impacts on humans (Hg, Al, Sb, As, Ba, … URL EndNote PDF Read more...

Usman M., Dyer P.S., Brock M., Wade C.M. & Khalid A.N. (2024): Two novel species of arctic-alpine lichen-forming fungi (Ascomycota, Megasporaceae) from the Deosai Plains, Pakistan - MycoKeys, 102: 285–299

Members of the lichen-forming fungal genus Oxneriaria are known to occur in cold polar and high altitudinal environments. Two new species, Oxneriaria crittendenii and O. deosaiensis, are now described from the high altitude Deosai Plains, Pakistan, based on phenotypic, multigene phylogenetic and chemical evidence. Phenotypically, O. crittendenii is characterised by orbicular light-brown thalli 1.5–5 cm across, spot tests (K, C, KC) negative, apothecia pruinose, hymenium initially blue then dark … URL EndNote PDF Read more...

Davydov E.A., Himelbrant D.E., Kuznetsova E.S., Stepanchikova I.S. & Yakovchenko L.S. (2024): Multilocus molecular phylogeny of the Umbilicaria aprina group (Umbilicariaceae, lichenized Ascomycota) supports species level and neo-endemic status of Umbilicaria krascheninnikovii - Plants, 13(5): 729 [23 p.]

The Northeast Asian endemic species of lichen-forming fungus Umbilicaria krascheninnikovii is herein discussed in the global context of biogeography and phylogeny of the U. aprina group. The name U. krascheninnikovii has been erroneously used by lichenologists for Umbilicaria spp. from high latitudes or altitudes worldwide, as there are omphalodisc apothecia and rough “crystals” of a necral layer on the upper surface. To test the monophyly and phylogenetic relationships within the U. aprina group, … URL EndNote PDF Read more...

Arcadia L. in (2023): (2995) Proposal to conserve the name Diplotomma chlorophaeum (Hepp ex Leight.) K.P. Singh & S.R. Singh against D. chlorophaeum Szatala (lichenized Ascomycota) - Taxon, 72(6): 1365–1366

The lichen originally described as Lecidea chlorophaea Hepp ex Leight. (Lich. Fl. Gr. Brit.: 328. 1871) belongs in Diplotomma according to current generic concepts. Szatala (in Ann. Hist.-Nat. Mus. Natl. Hung. 48: 280. 1956) intended to make the combination D. chlorophaeum, but did not cite the place of publication of Leighton’s name and consequently his combination, as such, is not validly published (Art. 41.5, Turland & al. in Regnum Veg. 159. 2018). However, Szatala did include a Latin description, … URL EndNote PDF Read more...

Budak B., Kalin S.N. & Yapça Ö. (2024): Antiproliferative, antimigratory, and apoptotic effects of diffractaic and vulpinic acids as thioredoxin reductase 1 inhibitors on cervical cancer - Naunyn-Schmiedebergs Archives of Pharmacology, 397(3): 1525-1535

Cervical cancer is among the most frequently observed cancer types in females. New therapeutic targets are needed because of the side impacts of existing cancer drugs and the inadequacy of treatment methods. Thioredoxin reductase 1 (TrxR1) is often overexpressed in many cancer cells, and targeting TrxR1 has become an attractive target for cancer therapy. This study investigated the anticancer impacts of diffractaic and vulpinic acids, lichen secondary metabolites, on the cervical cancer HeLa cell … URL EndNote PDF Read more...

Jung P.T., Briegel-Williams L., Werner L., Jost E., Schultz M., Nuernberg D.J., Grube M. & Lakatos M. (2024): A direct PCR approach with low-biomass insert opens new horizons for molecular sciences on cryptogam communities - Applied and Environmental Microbiology, 2024: 1-16

Molecular sequence data have transformed research on cryptogams (e.g., lichens, microalgae, fungi, and symbionts thereof) but methods are still strongly hampered by the small size and intermingled growth of the target organisms, poor cultivability and detrimental effects of their secondary metabolites. Here, we aim to showcase examples on which a modified direct PCR approach for diverse aspects of molecular work on environmental samples concerning biocrusts, biofilms, and cryptogams gives new options … URL EndNote PDF Read more...
