Past observations and experimental manipulations indicate that projected global change effects, including the increase of CO<sub>2</sub> concentration, temperature, change of precipitation and nitrogen (N) deposition, affect fungal species and communities in soils. Although the observed effects depend on the size and duration of change and reflect local conditions, increased N deposition seems to have the most profound effect on fungal communities. The plant-mutualistic fungal guilds - ectomycorrhizal fungi and arbuscular mycorrhizal fungi - appear to be especially responsive to global change factors with N deposition and warming seemingly having the strongest adverse effects. While global change effects on fungal biodiversity seem to be limited, multiple studies demonstrate increases in abundance and dispersal of plant pathogenic fungi. Additionally, ecosystems weakened by global change-induced phenomena, such as drought, are more vulnerable to pathogen outbreaks. The shift from mutualistic fungi to plant pathogens is likely the largest potential threat for the future functioning of natural and managed ecosystems. However, our ability to predict global change effects on fungi is still insufficient and requires further experimental work and long-term observations. <b>Citation:</b> Baldrian P, Bell-Dereske L, Lepinay C, Větrovský T, Kohout P (2022).

The phylogeny of <i>Mortierellaceae</i> was recently resolved based on current state of the art molecular techniques, and the paraphyletic genus <i>Mortierella sensu lato</i> (<i>s.l.</i>) was divided into 13 monophyletic genera. Our extensive sampling campaigns in the Austrian Alps resulted in 139 different <i>Mortierellaceae</i> pure culture isolates representing 13 new species. For the definition of taxa, we applied both classical morphological criteria, as well as modern DNA-based methods. Phylogenetic relationships were resolved based on the ribosomal DNA internal transcribed spacer (rDNA ITS), the large subunit (LSU), and the DNA-directed RNA polymerase II largest subunit 1 (<i>RPB1</i>). In this study, we proposed a new genus and described 13 new species belonging to the genera <i>Entomortierella</i>, <i>Linnemannia</i>, <i>Mortierella</i> and <i>Podila</i>. In addition, we proposed eight new combinations, re-defined <i>E. jenkinii</i> at species level, defined a neotype for <i>M. alpina</i> and lecto- as well as epitypes for <i>M. fatshederae</i>, <i>M. jenkinii,</i> and <i>M. longigemmata.</i> The rDNA ITS region is generally applied as classical barcoding gene for fungi. However, the obtained phylogenetic resolution is often too low for an accurate identification of closely related species of <i>Mortierellaceae</i>, especially for small sampling sizes. In such cases, unambiguous identification can be obtained based on morphological characters of pure culture isolates. Therefore, we also provide dichotomous keys for species identification within phylogenetic lineages. <b>Taxonomic novelties:</b> <b>new genus:</b> <i>Tyroliella</i> Telagathoti, Probst & Peintner; <b>New species:</b> <i>Entomortierella galaxiae</i> Telagathoti, M.

The genus has historically been divided into three morphological sections, <i>i.e.</i> <i>Chloridium</i>, <i>Gongromeriza</i>, and <i>Psilobotrys</i>. Sexual morphs have been placed in the widely perceived genus <i>Chaetosphaeria</i>, but unlike their asexual counterparts, they show little or no morphological variation. Recent molecular studies have expanded the generic concept to include species defined by a new set of morphological characters, such as the collar-like hyphae, setae, discrete phialides, and penicillately branched conidiophores. The study is based on the consilience of molecular species delimitation methods, phylogenetic analyses, ancestral state reconstruction, morphological hypotheses, and global biogeographic analyses. The multilocus phylogeny demonstrated that the classic concept of <i>Chloridium</i> is polyphyletic, and the original sections are not congeneric. Therefore, we abolish the existing classification and propose to restore the generic status of <i>Gongromeriza</i> and <i>Psilobotrys</i>. We present a new generic concept and define <i>Chloridium</i> as a monophyletic, polythetic genus comprising 37 species distributed in eight sections. In addition, of the taxa earlier referred to <i>Gongromeriza</i>, two have been redisposed to the new genus <i>Gongromerizella</i>. Analysis of published metabarcoding data showed that <i>Chloridium</i> is a common soil fungus representing a significant (0.3 %) proportion of sequence reads in environmental samples deposited in the GlobalFungi database. The analysis also showed that they are typically associated with forest habitats, and their distribution is strongly influenced by climate, which is confirmed by our data on their ability to grow at different temperatures. We demonstrated that <i>Chloridium</i> forms species-specific ranges of distribution, which is rarely documented for microscopic soil fungi. Our study shows the feasibility of using the GlobalFungi database to study the biogeography and ecology of fungi. <b>Taxonomic novelties:</b> <b>New genus:</b> <i>Gongromerizella</i> Réblová; <b>New sections:</b> <i>Chloridium</i> section <i>Cryptogonytrichum</i> Réblová, Hern.-Restr., M.

The taxonomy of the <i>Ophiostomatales</i> was confused for many years, mainly due to the convergent evolution of morphological characters used to delimit unrelated fungal taxa. The emergence of DNA-based methods has resolved much of this confusion. However, the delineation of some genera and the placement of various species and smaller lineages remains inconclusive. In this study we reconsidered the generic boundaries within the <i>Ophiostomatales</i>. A phylogenomic framework constructed from genome-wide sequence data for 31 species representing the major genera in the Order was used as a guide to delineate genera. This framework also informed our choice of the best markers from the currently most commonly used gene regions for taxonomic studies of these fungi. DNA was amplified and sequenced for more than 200 species, representing all lineages in the Order. We constructed phylogenetic trees based on the different gene regions and assembled a concatenated data set utilising a suite of phylogenetic analyses. The results supported and confirmed the delineation of nine of the 14 currently accepted genera, <i>i.e.</i> <i>Aureovirgo, Ceratocystiopsis, Esteya, Fragosphaeria, Graphilbum, Hawksworthiomyces, Ophiostoma, Raffaelea</i> and <i>Sporothrix</i>. The two most recently described genera, <i>Chrysosphaeria</i> and <i>Intubia</i>, were not included in the multi-locus analyses. This was due to their high sequence divergence, which was shown to result in ambiguous taxonomic placement, even though the results of phylogenomic analysis supported their inclusion in the <i>Ophiostomatales</i>. In addition to the currently accepted genera in the <i>Ophiostomatales</i>, well-supported lineages emerged that were distinct from those genera. These are described as novel genera. Two lineages included the type species of <i>Grosmannia</i> and <i>Dryadomyces</i> and these genera are thus reinstated and their circumscriptions redefined. The descriptions of all genera in the <i>Ophiostomatales</i> were standardised and refined where this was required and 39 new combinations have been provided for species in the newly emerging genera and one new combination has been provided for <i>Sporothrix</i>. The placement of <i>Afroraffaelea</i> could not be confirmed using the available data and the genus has been treated as <i>incertae sedis</i> in the <i>Ophiostomatales</i>. <i>Paleoambrosia</i> was not included in this study, due to the absence of living material available for this monotypic fossil genus.

Recent studies showed that most of the traditionally defined genera in <i>Chaetomiaceae</i> are highly polyphyletic. Many of these morphology-based genera, such as <i>Chaetomium</i>, <i>Thielavia</i> and <i>Humicola</i>, have been redefined using multigene phylogenetic analysis combined with morphology; however, a comprehensive taxonomic overview of the family is lacking. In addition, the phylogenetic relationship of thermophilic <i>Chaetomiaceae</i> species with non-thermophilic taxa in the family is largely unclear due to limited taxon sampling in previous studies. In this study, we provide an up-to-date overview on the taxonomy and phylogeny of genera and species belonging to <i>Chaetomiaceae</i>, including an extensive taxon sampling of thermophiles. A multigene phylogenetic analysis based on the ITS (internal transcribed spacers 1 and 2 including the 5.8S nrDNA), LSU (D1/D2 domains of the 28S nrDNA), <i>rpb2</i> (partial RNA polymerase II second largest subunit gene) and <i>tub2</i> (β-tubulin gene) sequences was performed on 345 strains representing <i>Chaetomiaceae</i> and 58 strains of other families in <i>Sordariales</i>. Divergence times based on the multi-gene phylogeny were estimated as aid to determine the genera in the family. Genera were delimited following the criteria that a genus must be a statistically well-supported monophyletic clade in both the multigene phylogeny and molecular dating analysis, fall within a divergence time of over 27 million years ago, and be supported by ecological preference or phenotypic traits. Based on the results of the phylogeny and molecular dating analyses, combined with morphological characters and temperature-growth characteristics, 50 genera and 275 species are accepted in <i>Chaetomiaceae</i>. Among them, six new genera, six new species, 45 new combinations and three new names are proposed. The results demonstrate that the thermophilic species fall into seven genera (<i>Melanocarpus</i>, <i>Mycothermus</i>, <i>Remersonia</i>, <i>Thermocarpiscus</i> <i>gen. nov</i>., <i>Thermochaetoides</i> <i>gen. nov</i>., <i>Thermothelomyces</i> and <i>Thermothielavioides</i>). These genera cluster in six separate lineages, suggesting that thermophiles independently evolved at least six times within the family. A list of accepted genera and species in <i>Chaetomiaceae</i>, together with information on their MycoBank numbers, living ex-type strains and GenBank accession numbers to ITS, LSU, <i>rpb2</i> and <i>tub2</i> sequences is provided.

The double-walled basidiospores with ornamented endospore walls are the characteristic features of <i>Ganodermataceae</i>. It is a large and complex family; although many studies have focused on <i>Ganodermataceae</i>, the global diversity, geographic distribution, taxonomy and molecular phylogeny of <i>Ganodermataceae</i> still remained incompletely understood. In this work, taxonomic and phylogenetic studies on worldwide species of <i>Ganodermataceae</i> were carried out by morphological examination and molecular phylogenetic analyses inferred from six gene loci including the internal transcribed spacer regions (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), the second largest subunit of RNA polymerase II gene (<i>rpb2</i>), the translation elongation factor 1-α gene (<i>tef1</i>), the small subunit mitochondrial rRNA gene (mtSSU) and the small subunit nuclear ribosomal RNA gene (nSSU). A total of 1 382 sequences were used in the phylogenetic analyses, of which 817 were newly generated, including 132 sequences of ITS, 139 sequences of nLSU, 83 sequences of <i>rpb2</i>, 124 sequences of <i>tef1</i>, 150 sequences of mtSSU and 189 sequences of nSSU. The combined six-gene dataset included sequences from 391 specimens representing 146 taxa from <i>Ganodermataceae</i>.
