Morphology, anatomy, chemistry, habitat, distribution and interrelation between the species are discussed. A key to the treated species is presented. Five species are described as new; Heterodermia andina, H. arvidssonii, H. badia, H....

... Members of the Heterodermia-complex (Physciaceae) can easily be recognized based on cilia that cover their lobed, grayish to white thalli and among foliose lichens they are one of the most common lichens in tropical and subtropical regions, with a few species reaching temperate regions. Many 'Heterodermia' species have been described from North America, India, Africa, Europe, Thailand and many other regions (Moberg 2011;Mongkolsuk et al. 2015). However, only recently this Heterodermia-complex was investigated based on a multigen phylogenetic approach so that Heterodermia s.lat. ...
Some deserts on Earth such as the Namib or the Atacama are influenced by fog which can lead to the formation of local fog oases-unique environments hosting a great diversity of specialized plants and lichens. Lichens of the genera Ramalina, Niebla or Het-erodermia have taxonomically been investigated from fog oases around the globe but not from the Atacama Desert, one of the oldest and driest deserts. Conditioned by its topography and the presence of orographic fog, the National Park Pan de Azúcar in the Atacama Desert is considered to be such a lichen hotspot. Applying multi-gen loci involving phylogenetic analyses combined with intense morphological and chemical characterization, we determined the taxonomic position of five of the most abundant epiphytic lichens of this area. We evaluated Roccellinastrum spongoideum and Hetero-dermia follmannii which were both described from the area but also finally showed that the genus Cenozosia is the endemic sister genus to Ramalina, Vermilacinia, Namibialina and Niebla. As a result, we have described the species Heterodermia adunca, C. cava and C. excorticata as new lichen species. This work provides a comprehensive dataset for common fog lichen genera of the Coastal Range of the Atacama Desert that can be used as a baseline for monitoring programs and environmental health assessments.
... This comparative study of lichen-associated bacteria found that lichen samples VP-CM-021 and VP-CM-023 had the greatest species richness and phylogenetic diversity. Both belonged to the genus Heterodermia, a lichen genus typically found in tropical and subtropical regions 22 . Previous research showed that the most abundant bacteria in the lichen Heterodermia obscurata were Proteobacteria (> 80%), followed by Actinobacteria, Acidobacteriota, and Myxococcota 23 . ...
Ten samples of tropical lichens collected from Doi Inthanon, Thailand, were explored for the diversity of their bacterial microbiomes through 16S rRNA-based metagenomics analysis. The five predominant lichen-associated bacteria belonged to the phyla Proteobacteria (31.84%), Planctomycetota (17.08%), Actinobacteriota (15.37%), Verrucomicrobiota (12.17%), and Acidobacteriota (7.87%). The diversity analysis metric showed that Heterodermia contained the highest bacterial species richness. Within the lichens, Ramalina conduplicans and Cladonia rappii showed a distinct bacterial community from the other lichen species. The community of lichen-associated actinobacteria was investigated as a potential source of synthesized biologically active compounds. From the total Operational Taxonomic Units (OTUs) found across the ten different lichen samples, 13.21% were identified as actinobacteria, including the rare actinobacterial genera that are not commonly found, such as Pseudonocardia, Kineosporia, Dactylosporangium, Amycolatopsis, Actinoplanes, and Streptosporangium. Evaluation of the pretreatment method (heat, air-drying, phenol, and flooding) and isolation media used for the culture-dependent actinobacterial isolation revealed that the different pretreatments combined with different isolation media were effective in obtaining several species of actinobacteria. However, metagenomics analyses revealed that there were still several strains, including rare actinobacterial species, that were not isolated. This research strongly suggests that lichens appear to be a promising source for obtaining actinobacteria.
... Additional information is hidden in a multitude of publications, which do not deal specifically with Ecuadorian lichens or lichenicolous fungi (e.g. Moberg 1990, 1993, 2011, Nöske 2004. Much unpublished material exists in various herbaria. ...
Altogether 322 taxa of lichens and lichenicolous fungi are reported from Ecuador of which many are probably new records for the country. These include five species which are described as new to science: Bacidia andina, Bacidina pulverula, Distopyrenis epidiorygma, Pertusaria lucidotetra and P. pseudoparnassia . From the separately treated genera Lepra and Pertusaria , 12 species are recorded for Ecuador and/or other Neotropical countries. Notes on morphology, chemistry and ecology are given.

The present paper enumerated the occurrence of 30 different species of lichens collected from 2 different study sites situated in 2 districts of Mizoram. It included Crustose (12 sp.), Foliose (16 sp.) and Fruticose (2 sp.) along with 9 species named as Diploschistes scruposus (Schreb.) Norman, Diorygma macgregorii (Vain.)

Hafellner & Bellem., Parmotrema austrosinense (Zahlbr.) Hale, Parmotrema crinitoides J.C. Wei, Parmotrema nilgherrense (Nyl.) Hale, Parmotrema rampoddense (Nyl.) Hale reported as a new record for the 1st time to the state of Mizoram, Northeast India. The finding were correlated with other previous reports on lichens and it provided detailed overview of documentation, distribution and diversity of lichens found in the small state like Mizoram under Indo-Burma region. Therefore, the richness of lichen diversity indicates the conditions of good forest health in Mizoram. The study also submits the need of conservation and exploration in the unexplored areas. HIGHLIGHTS The insight of the lichens diversity of the Mizoram state now provides the open platform for Lichenologist as well as Environmentalist The report of few species for the first time from the forest dominated hilly region of Mizoram had shown the richness of lichen distribution and its diversity As urbanisations as well as infrastructures developments are taking places in the remote corner of the state, it is very essential to explore the lichens diversities GRAPHICAL ABSTRACT

The lichen diversity of the Caribbean region of Colombia is one of the least known in the county. In the Sierra Nevada de Santa Marta (SNSM), whose forests are at risk of disappearing due to deforestation, 114 species of lichens have been recorded. We collected lichens at elevations from 500 to 2500 m on the northwestern slopes of the SNSM, and we report six genera and 19 species from this region for the first time. Our results highlight the importance of exploring new areas to enhance our knowledge of the lichens of SNSM and Colombia.

000 new field collections generated, the park checklist now includes 920 species, a 129% increase over estimates made two decades ago. Nearly a quarter of the lichens reported in the park are known from only a single occurence whereas only 7% of the lichens are known from 20 or more occurences. An assessment of commonness/rarity for all 920 species indicates that nearly half of the park's lichens should be considered to be infrequent, rare, or exceptionally rare. We assessed the distributions of all 920 species and found that 54 are endemic to the southeastern United States, 30 are endemic to the southern Appalachians, and eight occur nowhere else than within the confines of the national park. We discuss biogeographical affinities of the park's lichen biota as a whole, delimiting six regional "floristic" connections. Our 11 years of research have resulted in the discovery of several species presumed to be extinct or near-extinct. We make one new combination (Fuscopannaria frullaniae) and describe five species as new to science, each commemorating National Park Service staff instrumental to the completion of the study: Heterodermia langdoniana, Lecanora darlingiae, Lecanora sachsiana, Leprocaulon nicholsiae, and Pertusaria superiana.
