- UNITE (https://unite.ut.ee) is a web-based database and sequence management environment for molecular identification of eukaryotes. It targets the nuclear ribosomal internal transcribed spacer (ITS) region and offers nearly 10 million such sequences for reference. These are clustered into similar to 2.4M species hypotheses (SHs), each assigned a unique digital object identifier (DOI) to promote unambiguous referencing across studies. UNITE users have contributed over 600 000 third-party sequence annotations, which are shared with a range of databases and other community resources. Recent improvements facilitate the detection of cross-kingdom biological associations and the integration of undescribed groups of organisms into everyday biological pursuits. Serving as a digital twin for eukaryotic biodiversity and communities worldwide, the latest release of UNITE offers improved avenues for biodiversity discovery, precise taxonomic communication and integration of biological knowledge across platforms.

The taxon hypothesis paradigm—On the unambiguous detection and communication of taxa
- 2020

Ingår i: Microorganisms. - : MDPI AG. - 2076-2607. ; 8:12

Tidskriftsartikel (refereegranskat)abstract
- Here, we describe the taxon hypothesis (TH) paradigm, which covers the construction, identification, and communication of taxa as datasets. Defining taxa as datasets of individuals and their traits will make taxon identification and most importantly communication of taxa precise and reproducible. This will allow datasets with standardized and atomized traits to be used digitally in identification pipelines and communicated through persistent identifiers. Such datasets are particularly useful in the context of formally undescribed or even physically undiscovered species if data such as sequences from samples of environmental DNA (eDNA) are available. Implementing the TH paradigm will to some extent remove the impediment to hastily discover and formally describe all extant species in that the TH paradigm allows discovery and communication of new species and other taxa also in the absence of formal descriptions. The TH datasets can be connected to a taxonomic backbone providing access to the vast information associated with the tree of life. In parallel to the description of the TH paradigm, we demonstrate how it is implemented in the UNITE digital taxon communication system. UNITE TH datasets include rich data on individuals and their rDNA ITS sequences. These datasets are equipped with digital object identifiers (DOI) that serve to fix their identity in our communication. All datasets are also connected to a GBIF taxonomic backbone. Researchers processing their eDNA samples using UNITE datasets will, thus, be able to publish their findings as taxon occurrences in the GBIF data portal. UNITE species hypothesis (species level THs) datasets are increasingly utilized in taxon identification pipelines and even formally undescribed species can be identified and communicated by using UNITE. The TH paradigm seeks to achieve unambiguous, unique, and traceable communication of taxa and their properties at any level of the tree of life. It offers a rapid way to discover and communicate undescribed species in identification pipelines and data portals before they are lost to the sixth mass extinction. © 2020 by the authors.

A revised genus-level classification for Cerrenaceae (Polyporales, Agaricomycetes)
- 2023
-
Ingår i: Fungal Systematics and Evolution. - 2589-3831. ; 12:1, s. 271-322
-
Tidskriftsartikel (refereegranskat)abstract
- Cerrenaceae is a small family of polypores and hydnoid fungi in the order Polyporales (Basidiomycota). The family consists of white-rot fungi, some of which are serious tree pathogens. Combining morphological evidence with a phylogenetic dataset of six genetic markers, we revise generic concepts in the family and propose a seven-genus classification system for the family. Two genera are introduced as new: the monotypic Acanthodontia for Radulodon cirrhatinus, and Lividopora for the Rigidoporus vinctus complex. We re-introduce the name Somion for the Spongipellis delectans complex. Other recognized genera in the family are Cerrena, Irpiciporus, Pseudolagarobasidium, and Radulodon. New species introduced are Irpiciporus branchiformis from Tanzania, Lividopora armeniaca, and L. facilis from Southeast Asia, and Somion strenuum from East Asia. We provide nomenclatural comments on all the names combined to the above Cerrenaceae genera and typify Cerrena unicolor, C. zonata, Polyporus carneopallens (= L. vincta), Somion occarium, and S. unicolor. The genus Hyphoradulum belongs to Cystostereaceae (Agaricales), and we transfer the type species H. conspicuum to Crustomyces. Our study highlights the importance of integrating different basidiocarp types in analyses when revising genus classification in macrofungi.

- The North European species of Elaphomyces section Elaphomyces (Eurotiales, Pezizomycotina) are studied. Three new species, E. citrinopapillatus, E. pusillus, and E. roseoviolaceus are introduced and verified by morphology and sequence data from ITS, nuclear LSU, mitochondrial SSU, and β-tubulin. A lectotype for Elaphomyces granulatus is selected. Elaphomyces granulatus and E. muricatus are epitypified with sequenced material from the Femsjö region in South Sweden. Elaphomyces striatosporus is epitypified with sequenced material from the vicinity of the type locality in Norway. A key to all species of Elaphomyces occurring in Denmark, Norway, and Sweden is provided.

Four new species of Hydnellum (Thelephorales, Basidiomycota) with a note on Sarcodon illudens
- 2021
-
Ingår i: Fungal Systematics and Evolution. - : Westerdijk Fungal Biodiversity Institute. - 2589-3823 .- 2589-3831. ; 7, s. 233-254
-
Tidskriftsartikel (refereegranskat)abstract
- Four new Hydnellum species are described. Hydnellum roseoviolaceum sp. nov. grows in dry pine heaths on acidic, sandy soil. It is close to H. fuligineoviolaceum, another pine-associated species, but differs by smaller spores, an initially rose-coloured instead of violet flesh in fresh basidiomata and a mild taste. Hydnellum scabrosellum sp. nov. grows in coniferous forests on calcareous soil. It shares a general morphology with H. scabrosum, which also is its closest relative. It differs by having smaller and slenderer basidiomata and by the yellowish ochraceous colour of flesh and spines in dried specimens compared to the whitish or reddish brown colour seen in H. scabrosum. Hydnellum fagiscabrosum sp. nov. is another species with morphological and phylogenetic affinities to H. scabrosum. However, it is associated with trees from Fagales whereas H. scabrosum is associated with Pinaceae. Hydnellum nemorosum sp. nov. is yet another species that associates with broadleaved trees. It seems to be a rare species, morphologically reminiscent of H. fuligineoviolaceum, H. ioeides and H. scabrosum, but it is phylogenetically close to H. fennicum. Sequences from the type specimens of H. glaucopus, H. lepidum, H. scabrosum, Sarcodon illudens and S. regalis are included in the analyses. Specimens given the provisional name “Sarcodon pseudoglaucopus” in Sweden are now shown to be referable to S. illudens. The analyses further showed that S. illudens is close to H. lepidum. The new combination Hydnellum illudens is proposed. Sarcodon regalis and H. lepidum are shown to be conspecific and, although their basionyms were simultaneously published, the name S. regalis was only validated in a later publication. Hydnellum lepidum therefore takes priority and S. regalis becomes a synonym.

Polyozellus vs. Pseudotomentella: generic delimitation with a multi-gene dataset
- 2021
-
Ingår i: Fungal Systematics and Evolution. - : Westerdijk Fungal Biodiversity Institute. - 2589-3823. ; 8, s. 143-154
-
Tidskriftsartikel (refereegranskat)abstract
- Polyozellus and Pseudotomentella are two genera of closely related, ectomycorrhizal fungi in the order Thelephorales; the former stipitate and the latter corticioid. Both are widespread in the Northern Hemisphere and many species from both genera seem to be restricted to old growth forest. This study aimed to: a) identify genetic regions useful in inferring the phylogenetic relationship between Polyozellus and Pseudotomentella, b) infer this relationship with the regions identified and c) make any taxonomic changes warranted by the result. RPB2, mtSSU and nearly full-length portions of nrLSU and nrSSU were found to be comparatively easy to sequence and provide a strong phylogenetic signal. A STACEY species tree of these three regions revealed that Polyozellus makes Pseudotomentella paraphyletic. As a result, nearly all species currently placed in Pseudotomentella were recombined to Polyozellus. Pseudotomentella larsenii was found to be closer to Tomentellopsis than Polyozellus, but its placement needs further study and it was hence not recombined.

Pseudotomentella badjelanndana, Pseudotomentella sorjusensis and Tomentella viridibasidia—three new corticioid Thelephorales species from the Scandes Mountains
- 2021
-
Ingår i: Phytotaxa. - : Magnolia Press. - 1179-3155 .- 1179-3163. ; 497:2, s. 61-78
-
Tidskriftsartikel (refereegranskat)abstract
- One Tomentella and two Pseudotomentella species are described from alpine areas of Sweden and Norway. Tomentella viridibasidia sp. nov. is genetically closely related to T. bryophila, but is morphologically most similar to T. olivascens and T. stuposa. Pseudotomentella badjelanndana sp. nov. and P. sorjusensis sp. nov. belong to the P. tristis group. At least P. sorjusensis must currently be regarded as morphologically cryptic with P. rotundispora. Basidiomata of the new species have only been encountered in the Scandes Mountains, but root-tip and soil sequences indicate that all three are geographically widespread. An updated key to the Pseutomentella tristis group is provided.
