- We report here the draft de novo genome assembly, transcriptome assembly, and annotation of the lichen-forming fungus Arthonia radiata (Pers.) Ach., the type species for Arthoniomycetes, a class of lichen-forming, lichenicolous, and saprobic Ascomycota. The genome was assembled using overlapping paired-end and mate pair libraries and sequenced on an Illumina HiSeq 2500 instrument.

The future of dna barcoding : Reflections from early career researchers
- 2021

Ingår i: Diversity. - : MDPI AG. - 1424-2818. ; 13:7

Tidskriftsartikel (refereegranskat)abstract
- Over the last two decades, the use of DNA barcodes has transformed our ability to identify and assess life on our planet. Both strengths and weaknesses of the method have been exemplified through thousands of peer-reviewed scientific articles. Given the novel sequencing approaches, currently capable of generating millions of reads at low cost, we reflect on the questions: What will the future bring for DNA barcoding? Will identification of species using short, standardized fragments of DNA stand the test of time? We present reflected opinions of early career biodiversity researchers in the form of a SWOT analysis and discuss answers to these questions.

Molecular systematics and character evolution in the lichen family Ramalinaceae (Ascomycota: Lecanorales)
- 2018
-

- The Ramalinaceae is the fourth-largest family of lichenized ascomycetes with 42 genera and 913 species exhibiting considerable morphological variation. Historically, generic boundaries in the Ramalinaceae were primarily based on morphological characters. However, molecular systematic investigations of subgroups revealed that current taxonomy is at odds with evolutionary relationships. Tropical members of the family remain particularly understudied, including the large genus Phyllopsora. We have generated and collected multilocus sequence data (mtSSU, nrITS, nrLSU, RPB1, RPB2) for 149 species associated with the Ramalinaceae and present the first comprehensive molecular phylogeny of the family. We used ancestral state reconstructions on our molecular family phylogeny to trace the evolution of character states. Our results indicate that the Ramalinaceae have arisen from an ancestor with long, multiseptate ascospores living in humid temperate forests, and that the phyllopsoroid growth form has evolved multiple times within the family. Based on our results using integrative taxonomy, we discuss sister-relations and taxon-delimitation within five well-supported clades: The Bacidia, Biatora- ,Ramalina-, Rolfidium-, and Toninia-groups. We reduce six genera into synonymy and make 49 new nomenclatural combinations. The genera Bacidia, Phyllopsora, Physcidia and Toninia are polyphyletic and herein split into segregates. We describe the two genera Bellicidia and Parallopsora and resurrect the genera Bibbya, Kiliasia, Sporacestra, and Thalloidima. According to our new circumscription, which also includes some additional changes, the family Ramalinaceae now comprises 39 genera.

Towards an integrative taxonomy of Phyllopsora (Ramalinaceae)

- Species identification in the tropical lichen genus Phyllopsora is generally challenging and is based on ascospore morphology, vegetative dispersal units, thallus structure and secondary chemistry. As several type specimens are in poor condition and difficult to interpret, it is often unclear how these old names fit with the currently used taxonomy. In the present study, we aim to identify species boundaries in Phyllopsora s. str. supported by an integrative approach using multiple sources of evidence. We investigated a substantial amount of herbarium as well as freshly collected material and generated mtSSU and ITS sequence data from most of the described species, including several types. Species delimitation analyses are applied on the gene trees using mPTP and we construct a species tree of both markers with *BEAST, facilitating discussion of species delimitation and sister-relationships. Comparing morphology, chemistry and molecular data, we found that the mPTP analyses split established species repeatedly. Based on our integrative results, we exclude nine species from the genus, resurrect one (P. melanoglauca Zahlbr.), reduce two into synonymy with other Phyllopsora species and describe five as new to science: Phyllopsora amazonica Kistenich & Timdal (which shares the secondary chemistry (atranorin and terpenoid pattern) with P. halei chemotype 1, but differs, e.g., in having smaller areolae that are attached to a thinner, white prothallus, and in having more persistently marginate and less convex apothecia), Phyllopsora concinna Kistenich & Timdal (which shares the secondary chemistry (atranorin and parvifoliellin) with P. parvifoliella and P. rappiana, but differs from both in forming larger isidia, having a white prothallus, apothecial margin paler than the disc, and longer and broader ascospores), Phyllopsora furfurella Kistenich & Timdal (which is here segregated from P. furfuracea based on having a white prothallus and in containing skyrin in the hypothecium (K+ red)), Phyllopsora isidosa Kistenich & Timdal (which differs from P. byssiseda in forming a more crustose thallus with more delicate isidia, and from P. isidiotyla in forming somewhat coarser, less branched isidia) and Phyllopsora neotinica Kistenich & Timdal (a neotropical species here segregated from the now exclusively paleotropical P. chodatinica, differing in containing an unknown xanthone (not chodatin)). Lectotypes are designated for Biatora pyrrhomelaena Tuck., Lecidea leucophyllina Nyl., L. pertexta Nyl., and P. brachyspora Mull. Arg. In total, we accept 54 species in the genus Phyllopsora.
