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...

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 many natural resources important for the economy and the population. These ecosystems, and the associated fungi, seem unique in the world and have never been investigated to date. They also remain vulnerable as they are highly sought over for wood, sand, and gravel. Our study aims to characte...

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...

28S sequence of Mycena chlorinosma (JCFR001), collected in an urban wood at Paul Sabatier University Campus, Toulouse, France.

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...
