We report two cases of coronavirus disease 2019 (COVID-19) in travellers from Wuhan, China to Thailand. Both were independent introductions on separate flights, discovered with thermoscanners and confirmed RT-PCR genome sequencing. do not seem directly linked the Huanan Seafood Market Hubei but viral genomes are identical four other sequences suggesting early spread within city already first week January.
The number of undescribed species lichenized fungi has been estimated at roughly 10,000. Describing and cataloging these would take the existing taxonomists several decades; however, support for taxonomy is in decline worldwide. In this paper we emphasize dire need taxonomic expertise lichenology. We bring together 103 colleagues from institutions worldwide to describe a total 100 new fungi, representing wide geographic range. newly described are: Acarospora flavisparsa, A. janae,...
Summary We studied the evolutionary history of Parmeliaceae (Lecanoromycetes, Ascomycota), one largest families lichen‐forming fungi with complex and variable morphologies, also including several lichenicolous fungi. assembled a six‐locus data set nuclear, mitochondrial low‐copy protein‐coding genes from 293 operational taxonomic units ( OTU s). The lifestyle originated independently three times in lichenized ancestors within Parmeliaceae, new generic name is introduced for these In all...
Recent studies of the global diversity lichenized fungal family Graphidaceae suggest that there are a large number species remaining to be discovered. No less than 640 have been described since 2002, including 175 new introduced in collaborative effort single issue this journal. These findings largest tropical crustose lichens may an even higher Parmeliaceae. To estimate whether discovery is significant step forward cataloguing extant family, we employed parametric method predict richness...
The Cladia aggregata complex is one of the phenotypically most variable groups in lichenized fungi, making species determination difficult and resulting different classifications accepting between to eight species. Multi-locus DNA sequence data provide an avenue test delimitation scenarios using genealogical coalescent methods, employing gene trees. Here we tested molecular four loci (nuITS IGS rDNA, protein-coding GAPDH Mcm-7), including 474 newly generated sequences. Using a combination ML...
Muscarine is a toxic alkaloid produced by neurotoxic mushrooms, known for its heat stability. Ingesting muscarine-containing mushrooms rapidly stimulates the parasympathetic nervous system within 15 min, leading to mushroom poisoning. To address this issue, we developed an electrochemical sensor using screen-printed carbon electrode (SPCE) modified with gold detect muscarine. The behavior of muscarine was studied in acidic conditions 10 mM potassium dichromate (K2Cr2O7) as oxidizing agent...
In a continuation of our investigation lichenized fungi in Rondônia and adjacent areas, we present preliminary treatment the graphidoid thelotremoid core Graphidaceae (subfamilies Fissurinoideae Graphidoideae). A total 122 identified species are reported here, almost all which new reports to Rondônia, 37 science. This includes three new, monospecific genera, viz. Aggregatorygma triseptatum M. Cáceres, Aptroot & Lücking, phylogenetically distinct genus similar Diorygma but with corticate...
Abstract While the phylogenetic position of Trypetheliaceae has been subject recent molecular studies, relationships within this family have little studied. Here we construct a detailed genus‐level phylogeny family. We confirm previous morphology‐based findings suggesting that substantial proportion genera are not monophyletic, and an overemphasis placed on certain character state combinations which do strictly reflect relationships. Specifically, patterns ascospore septation, ostiole...
Molecular phylogenies often reveal that taxa circumscribed by phenotypical characters are not monophyletic. While re-examination of identifies the presence characterizing clades, there is a growing number studies fail to identify diagnostic characters, especially in organismal groups lacking complex morphologies. Taxonomists then can either merge or split into smaller entities. Due nature binomial nomenclature, this decision special importance at generic level. Here we propose new approach...
We provide an updated skeleton phylogeny of the lichenized family Graphidaceae (excluding subfamily Gomphilloideae), based on three loci (mtSSU, nuLSU, RPB2), to elucidate position four new genera, Aggregatorygma, Borinquenotrema, Corticorygma, and Paratopeliopsis, as well placement enigmatic species Diorygma erythrellum, Fissurina monilifera, Redingeria desseiniana. Based resulting topology, in addition tribes described previously, we recognize further Graphidoideae: Acanthothecieae...
Cases of mushroom poisoning in Thailand have increased annually. During 2008 to 2014, the cases reported National Institute Health included 57 deaths; at least 15 died after ingestion amanitas, most common lethal wild mushrooms inhabited. Hence, aims this study were identify samples from nine clinically during 7-year period based on nuclear ITS sequence data and diagnose peptide toxins using a reversed phase LC-MS method. Nucleotide similarity was identified BLAST search NCBI database...
A new revised checklist of lichenized fungi in Thailand is presented, including 1,292 species. Recent work on the taxonomy these organisms resulted an enormous increase our knowledge lichen biota country – current includes more than twice as many species previous catalogue published 15 years ago and phylogenetic studies numerous changes generic classification fungi. Hence, a here presented summarizing lichens Thailand. Six records are reported, viz. Acanthothecis salazinica, Bactrospora...
Abstract We provide an expanded and updated, 2-locus phylogeny (mtSSU, nuLSU) of the lichenized fungal family Trypetheliaceae , with a total 196 ingroup OTUs, in order to further refine generic delimitations species concepts this family. As result, following 15 clades are recognized as separate genera, including five newly established genera: Aptrootia Architrypethelium Astrothelium (including bulk corticate astrothelioid ascospores; synonyms: Campylothelium Cryptothelium Laurera ),...
The lichen-forming genus Pertusaria under its current circumscription is polyphyletic and phylogenetic affiliations are uncertain. Here we study the species of genera Varicellaria which contain lecanoric acid as major constituent, have disciform apothecia, strongly amyloid asci, non-amyloid hymenial gel, 1-2-spored 1- or 2-celled ascospores with thick, 1-layered walls. We infer relationships using maximum likelihood Bayesian analyses based on four molecular loci (mtSSU, nuLSU rDNA,...
ABSTRACTABSTRACTGraphidaceae is a large family of over 2000 predominantly tropical, lichenized fungal species encompassing remarkable range morphological and chemical diversity. The majority belongs in subfamily Graphidoideae, which also exhibits the greatest amount variation. Various phenotype characters have traditionally been used for classification at genus levels, but their correlations with phylogenetic clades are poorly known. Using multilocus approach, we reconstructed phylogeny 224...
We present an updated 3-locus molecular phylogeny of tribe Ocellularieae, the second largest within subfamily Graphidoideae in Graphidaceae. Adding 165 newly generated sequences from mitochondrial small subunit rDNA (mtSSU), nuclear large (nuLSU), and DNA-directed RNA polymerase II (RPB2), we currently distinguish 218 species among sequenced material, including outgroup. This corresponds to almost half at this point recognized tribe. The include 23 described one genus published elsewhere...
Phylogenetic relationships of the genera Cladia, Heterodea and Ramalinora were reconstructed using a combined dataset ribosomal nuclear ITS LSU mitochondrial SSU, protein-coding Mcm7 DNA sequences. Maximum likelihood Bayesian analyses strongly supported monophyletic group in which species foliose genus crustose nested within fruticose Cladia. Alternative hypothesis testing rejected an independent status Ramalinora. We tested that adaptive radiation led to morphological disparity found Cladia...
Two new genera, Myriochapsa M. Cáceres, Lücking & Lumbsch and Nitidochapsa Parnmen, Lumbsch, are introduced for the species Chapsa psoromica C. leprieurii, which not genuine but related to Myriotrema Ocellularia, respectively. The following two combinations proposed: (M. Santos de Jesus Vieira) comb. nov., leprieurii (Mont.) nov. is morphologically chemically similar differs in wider apothecial pore with fissured-lobulated margin; it known only from western Amazon (Brazil: Rondônia)....
