- The filamentous fungus Podospora anserina has been used as a model organism for more than 100 years and has proved to be an invaluable resource in numerous areas of research. Throughout this period, P. anserina has been embroiled in a number of taxonomic controversies regarding the proper name under which it should be called. The most recent taxonomic treatment proposed to change the name of this important species to Triangularia anserina. The results of past name changes of this species indicate that the broader research community is unlikely to accept this change, which will lead to nomenclatural instability and confusion in literature. Here, we review the phylogeny of the species closely related to P. anserina and provide evidence that currently available marker information is insufficient to resolve the relationships amongst many of the lineages. We argue that it is not only premature to propose a new name for P. anserina based on current data, but also that every effort should be made to retain P. anserina as the current name to ensure stability and to minimise confusion in scientific literature. Therefore, we synonymise Triangularia with Podospora and suggest that either the type species of Podospora be moved to P. anserina from P. fimiseda or that all species within the Podosporaceae be placed in the genus Podospora.

- The order Sordariales is taxonomically diverse, and harbours many species with different lifestyles and large economic importance. Despite its importance, a robust genome-scale phylogeny, and associated comparative genomic analysis of the order is lacking.In this study, we examined whole-genome data from 99 Sordariales, including 52 newly sequenced genomes, and seven outgroup taxa. We inferred a comprehensive phylogeny that resolved several contentious relationships amongst families in the order, and cleared-up intrafamily relationships within the Podosporaceae. Extensive comparative genomics showed that genomes from the three largest families in the dataset (Chae-tomiaceae, Podosporaceae and Sordariaceae) differ greatly in GC content, genome size, gene number, repeat percentage, evolutionary rate, and genome content affected by repeat-induced point mutations (RIP). All genomic traits showed phylogenetic signal, and ancestral state reconstruction revealed that the variation of the properties stems primarily from within-family evolution. Together, the results provide a thorough framework for understanding genome evolution in this important group of fungi.

- The phylogenetic relationships of Lasiosphaeriaceae are complicated in that the family is paraphyletic and includes Sordariaceae and Chaetomiaceae, as well as several polyphyletic genera. This study focuses on the phylogenetic relationships of the coprophilous genera, Anopodium, Apodospora, Arnium, Fimetariella and Zygospermella. They are traditionally circumscribed based on ascospore characters, which have proven homoplasious in other genera within the family. Our results based on LSU nrDNA and ß–tubulin sequences distinguish four lineages ofLasiosphaeriaceae taxa. Anopodium joins the clade of morphologically similar, yellow-pigmented species of Cercophora and Lasiosphaeria. Apodospora is monophyletic and joins a larger group of taxa with unclear affinities to each other, while Arnium is polyphyletic being scattered throughout three of the four major clades of Lasiosphaeriaceae. Fimitariella is represented by a single collection and joins the clade containing Cercophora scortea and Podospora appendiculata. Zygospermellashows affinities to the Lasiosphaeris clade. Based on a combination of morphological and molecular data, Echria stat. nov. is recognized at the genus level for the former Arnium section and two new combinations are proposed: E. gigantospora and E. macrotheca.

Molecular phylogeny of Sydowiellaceae : resolving the position of Cainiella
- 2012

- Cainiella is an ascomycete genus associated with arctic alpine plants. The systematic position of Cainiella has long been unclear, with current classifications placing the genus in either Sordariales or Xylariales. Our molecular results, based on mtSSU, ITS and nLSU rDNA data, clearly show that the genus belongs in the Sydowiellaceae (Diaporthales). The study also includes new sequences of Sydowiellaceae and contributes to a better knowledge of the phylogenetic relationships of that family.

- The focus of this study is on Preussia sensu lato species with 8-celled ascospores. Two new species, P. alpina and P. octocylindrospora are introduced based on morphological characters and discussed in relation to similar species in the genus. New records are provided from Sporormiella corynespora, S. octomegaspora, P. octomera and P. octonalis. This greatly expands or reduces their geographical distribution ranges, as well as substrate preferences. In addition, a key to the coprophilous species with 8-celled ascospores is provided.

Phylogenetic relationships and an assessment of traditionally used taxonomic characters in the Sporormiaceae (Pleosporales, Dothideomycetes, Ascomycota), utilising multi-gene phylogenies

- The family Sporormiaceae (Pleosporales, Dothideomycetes, Ascomycota) occur worldwide and a majority of the species are coprophilous. The taxonomy and classification of the family are based on a small number of morphological and ecological characters. Several taxa are easily confused by their shared morphological features, and the relationships between genera are poorly known and in need of critical study. The aims of this study were to resolve the phylogenetic relationships within the Sporormiaceae, test the current generic classification, and study the utility of traditional characters for the taxonomy in the group. To resolve these questions, we analysed combined data sets of ITS-nLSU rDNA, mtSSU rDNA and beta-tubulin sequences with parsimony and Bayesian methods. The results showed that many characters, which previously have been used in the taxonomy and classification of the Sporormiaceae, such as the substrate choice, presence or absence of an ostiole, and presence or absence of germ slits, were all homoplastic and not useful for circumscribing monophyletic groups. A number of characters may be useful for circumscribing smaller clades if used in combination with other features, such as the shape of the ascus with the shape of the ascospores. Our phylogenetic analyses show that Preussia and Sporormiella are non-monophyletic, and a constrained analysis forcing these genera into monophyly resulted in significantly worse trees. Spororminula is nested in Preussia s. lat., and Eremodothis and Pycnidiophora are nested within Westerdykella. Finally, we suggest a new generic classification for the family Sporormiaceae, including Sporormia, Preussia (including Sporomiella and Spororminula) and Westerdykella (including Eremodothis and Pycnidiophora). We also propose 14 new combinations: Preussia alloiomera (S.I. Ahmed & Cain) Kruys, Preussia antarctica (Speg.) Kruys, Preussia bipartis (Cain) Kruys, Preussia borealis (I.Egeland) Kruys, Preussia dubia (S.I. Ahmed & Cain) Kruys, Preussia lignicola (W. Phillips & Plowr.) Kruys, Preussia longisporopsis (S.I. Ahmed & Cain) Kruys, Preussia minipascua (S.I. Ahmed & Cain) Kruys, Preussia octomera (Auersw.) Kruys, Preussia splendens (Cain) Kruys, Preussia tenerifae (Arx & Aa) Kruys, Preussia tetramera (S.I. Ahmed & Cain) Kruys, Westerdykella angulata (A.C. Das) Kruys and Westerdykella aurantiaca (J.N. Rai & J.P. Tewari) Kruys.

Species richness of coprophilous ascomycetes in relation to variable food intake by herbivores
- 2008

Ingår i: Fungal diversity. - 1560-2745 .- 1878-9129. ; 30, s. 73-81

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to study species richness and species composition of coprophilous ascomycetes in borcal forest. Dung was sampled at three localities and of three herbivores, moose (Alces alces), mountain hare (Lepus timidus), and roe deer (Capreolus capreolus). Species richness differed significantly among dung types and we also found a significant effect of the interaction between locality and dung type on the mean number of species. The highest species richness was found on roe deer dung. While moose did not differ from mountain hare. There was a strong positive relationship between the total number of ascomycete species and the number of plant species foraged by the three herbivores. We believe that food choice is one important factor influencing the species richness of coprophilous ascomycetes, and that some species are more associated with habitat and food choice of the herbivore, rather than a specific dung type/animal species. The composition of species on the different dung types is also discussed. Our results suggests that the coprophilous mycota in the boreal forest is poorly known, we found 47 species in total, four species were undescribed. I was new to Sweden, 24 species were new records for the province, and we made a total of 22 new substrate records.
