Understanding and describing the diversity of living organisms is a great challenge. Fungi have for a long time been, and unfortunately still are, underestimated when it comes to taxonomic research. The foundations were laid by the first mycologists through field observations. These important fundamental works have been and remain vital reference w...

Most empirical research on biological shortfalls has focused on vertebrate taxa. This is important given many species in poorly studied groups such as invertebrates, plants, and fungi are predicted to possess high conservation risk. Here, we focus on Laboulbeniomycetes: a class of microfungi that are understudied. We examined four shortfalls: Linne...

Fungi are one of the most diverse groups of organisms with an estimated number of species in the range of 2–3 million. The higher-level ranking of fungi has been discussed in the framework of molecular phylogenetics since Hibbett et al., and the definition and the higher ranks (e.g., phyla) of the ‘true fungi’ have been revised in several subsequen...

Fungal conservation is gaining momentum globally, but many challenges remain. To advance further, more data are needed on fungal diversity across space and time. Fundamental information regarding population sizes, trends, and geographic ranges is also critical to accurately assess the extinction risk of individual species. However, obtaining these...

With the simultaneous growth in interest from the mycological community to discover fungal species and classify them, there is also an important need to assemble all taxonomic information onto common platforms. Fungal classification is facing a rapidly evolving landscape and organizing genera into an appropriate taxonomic hierarchy is central to be...

Les surfaces occupées par les forêts naturelles de pin gris dans l’est du Canada sont en déclin dans les écosystèmes d’eskers, en raison de l’aménagement forestier actuel, soulevant des enjeux majeurs de conservation de la diversité fongique des sols. Cependant, nos connaissances sur la fonge des sols forestiers d’eskers, en particulier leur distri...

Fungi are among the least known organisms on earth, with an estimated number of species between 1.5 and 10 million. This number is expected to be refined, especially with increasing knowledge about microfungi in undersampled habitats and increasing amounts of data derived from environmental DNA sequencing. A significant proportion of newly generate...

Black spruce (Picea mariana (Mill.) B.S.P.) is the dominant conifer species across a large part of North American boreal forests, providing many goods and services essential to human activities, and playing a major climatic role through the global carbon cycle. However, a comprehensive synthesis of the effects of climate change on black spruce has...

The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-ca...

Boreal ecosystems are composed with numerous lakes of various shapes and sizes, some of which are composed of islands. Forested islands form forest-lake interfaces conducive to unique vegetation processes and disturbance dynamics. However, the role of forest structure and disturbance dynamics on islands environments and biodiversity has been little...

La conservation de la diversité des êtres vivants est devenue l'un des objectifs les plus importants de l'aménagement durable des forêts. Grâce aux nouvelles techniques de détection de l'ADN des organismes dans l'environnement, on redécouvre les territoires forestiers sous un nouveau jour. Les forêts sont en réalité le théâtre de nombreuses et dive...

Cette chronique est pour moi l’occasion de revisiter ce qu’on appelle communément les champignons forestiers; il s’agit d’une tentative d’aller au-delà de notre perception centrée sur le visible, afin de porter un regard différent sur la véritable nature des champignons lors de nos prochaines balades en forêt. This chronicle is an opportunity to r...

As individuals, our behaviour is an integral part of our interactions with the environment and is mainly determined by the interaction of our senses (Kapralos et al., 2017). One part of these sensory interactions is directly linked to one of our main biological functions, feeding. Have you ever wondered why we can taste? This question may seem basi...

Specimen collected in the Loubatière forest (France) in a beech stand, during early springtime. It was half-buried in leaf litter, on the edge of a stream, near a stand of horsetail. It is quite large, smooth hymenophore and has large mycelial cords at the base of the stipe. Microscopic examination remains to be done, especially to check the size o...

Résumé. Les auteurs décrivent en détails et illustrent la première récolte aveyronnaise de Leucopaxillus tricolor (Peck) Kühner, réalisée dans une forêt mixte à Agen-d’Aveyron, en août 2021. Cette espèce est considérée par de nombreux auteurs comme rare, et se retrouve incluse dans les listes rouges de nombreux pays. Abstract. The authors describe...

Eskers are fluvioglacial geological formations providing natural resources important for the economy and the population. The associated fungal communities have barely been investigated to date. These ecosystems are vulnerable as they are highly sought over for water, wood, sand and gravel. As a result, fungal communities of esker forests might be t...

Le rare Mycena chlorinosma Singer (Agaricales, Mycenaceae) a été trouvé lors d'un travail d'inventaire mycologique dans le bois de Pouciquot, situé sur le campus de l'université de Toulouse (France). Cette récolte constitue la huitième mention connue de cette espèce en France (métropole et outre-mer), la troisième en France métropolitaine. Une desc...

ITS and partial LSU sequences of a Pseudoclitocybe obbata collection from the French department of Aveyron.

Les Eskers sont des formations géologiques fluvio-glaciaires résultant du dépôt de sédiments dans des canaux sous-glaciaires ou à parois de glace pendant le retrait des glaciers il y a 10 000 ans. Ils fournissent une grande quantité de ressources naturelles cruciaux pour l’économie et la population, incluant entre autres une eau potable de grande q...

The five human senses are the result of complex psycho-physiological phenomena (Geldard, 1953) allowing us to perceive our environment. It is important to stress the psychoneurological aspect of biological processes involving our senses. Indeed, without this link between memory and senses, the latter would not be as important. Identifying a fungus...

A first official taxonomic checklist of myxomycetes from the French department Aveyron is presented. As the result of data collected by the Mycological and Botanical Association of Aveyron (AMBA), literature and online research, a total of 21 species representing 14 genera, 7 families and 5 orders, were recorded. The following information for each...
