“…A pigment database is also a prerequisite allowing to identify taxa based on pigment profiles. Modern chemical analysis methods as applied in this work, have now shown, that pigment profiles of dermocyboid Cortinarius species are indeed useful and valid characters for species delimitation, especially when pigment concentrations are considered in addition to pigment composition (Hannecker et al 2023 ). Pigments or fingerprints of other metabolites, e.g., of volatile organic carbons, have also proven to be suitable tools for species recognition in fungi (Peintner et al 2019 ; Telagathoti et al 2021 ).…”

“…The list of the collections of species examined in this study are provided (See Additional Material Table 2 ). The material was collected in samples of around 5 to 10 specimens, apart from a few smaller samples, and includes species of the subgenus Dermocybe used in our earlier studies (Siewert et al 2022 ; Hannecker et al 2023 ). Material was collected in Central Europe, mostly in coniferous alpine habitat.…”

Cortinarius (Fr.) Fr. is one of the most species-rich genera in the Agaricales (Basidiomycota). Cortinarius subgen. Dermocybe (Fr.) Trog includes brightly coloured Cortinarii with anthraquinone pigments. The chemotaxonomic approach has always been as important as classical methods for species definition of Dermocybe and helped to improve overall species concepts. However, some species concepts within this group remain unclear. We therefore address this topic based on a combined phylogenetic, morphological, and pigment-chemical approach. For this, sequence data, HPLC–MS pigment profiles and spore sizes were included were included to obtain a better resolution of taxa. The study was based on 173 recent collections and 12 type specimens. A total of 117 rDNA ITS sequences were produced from the collections in this study, 102 sequences were retrieved from databases. We could detect and clearly delimit 19 Dermocybe species occurring in central European habitats, from which 16 are discussed in detail. Additionally, we grouped the detected anthraquinone pigments into four groups. This detailed analysis of dermocyboid Cortinarius species occurring in a restricted number of habitat types confirmed our hypothesis that species diversity is much higher than currently assumed. This high diversity is blurred by too wide and incorrect species concepts of several classical species like C. croceus and C. cinnamomeus. Molecular and chemotaxonomical studies carried out together with careful phenotypical analyses resulted in a good differentiation of species. A key is presented for these taxa to allow a better identification of Cortinarius subgenus Dermocybe spp. occurring in Central Europe mainly in the alpine range.

“…Many basidiomycete pigments show structural similarity with plant pigments, which are known for light-activated defense strategies such as the production of radical oxygen species (Siewert, 2021). A first case study showed that some pigments of species of Cortinarius subgenus Dermocybe are photoactivated and had toxic effects on a glassworm species (Hannecker et al, 2023).…”

Fruit body-forming fungi are hyperdiverse and of central importance for the functioning of ecosystems worldwide. They provide habitat and resources for other organisms and perform critical roles in carbon and nutrient cycling. Like in animals and plants, fungal coloration is expected to play a fundamental role in response to biotic and abiotic environments, thus providing invaluable information to predict fungal and associated diversity in the Anthropocene. Despite centuries of plant and animal coloration research, the role of fruit body colors in fungal ecology remains mostly obscure. Essential questions are unresolved, such as: How do fruit body colors function to cope with abiotic stress? Do fruit body colors function to attract dispersal vectors or prevent predation via camouflage or aposematism? What is the significance of fruit body colors for fungal fitness? What are the implications of climate change-induced fruit body color change on fungal and associated biodiversity? Here, I review existing knowledge and outline several research trajectories to better understand the ecological role of fruit body colors. Revealing climate-driven adaptations and interactions with other organisms will improve forecasts under climate change for fungal diversity and interrelated biodiversity and inform cross-taxonomic conservation strategies.

Fungi are often considered a delicacy and are primarily cultivated and harvested, although numerous species are responsible for intoxication due to toxin content. Foodborne diseases are a significant public health concern, causing approximately 420 000 deaths and 600 million morbidities yearly, of which mushroom poisoning is one of the leading causes. Epidemiological data on non-cultivated mushroom poisoning in individual countries are often unrepresentative, as intoxication rarely requires emergency intervention. On the other hand, the lack of specialist knowledge among medical personnel about the toxicological manifestations of mushroom consumption may result in ineffective therapeutic interventions. This work aims to provide an easy-to-consult and wide-ranging tool useful for better understanding the variability of mushroom intoxications, the associated symptoms, and the main treatments for the most severe cases, given the absence of a complete species mapping tool toxic. Moreover, we establish an effective collection network that describes the incidence of mushroom poisonings by reporting the species and associated toxicological manifestations for each case. In conclusion, we highlight the need to establish appropriate primary prevention interventions, such as training the affected population and increasing consultancy relationships between mycological experts and specialised healthcare personnel.
