Cazabonne J. 2023. The Use of Humans Senses in the Identification of Mushrooms III – taste. Field Mycology, 24 (1): 29 – 31. Link.

Preview: 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 basic, but the underlying biological and evolutionary mecha- nisms deserve our attention (see Breslin, 2013 for evolutionary insights into human taste). Tasting the environment has allowed our ancestors to survive and pass on their genes (McLaughlin & Margolskee, 1994). This is crucial information for our organism and is enabled by a complex set of chemoreceptors that allow us to evaluate what we eat (Yarmolinsky et al., 2009). Apart from being an essential element for our survival, the sense of taste has been shown to be linked to the neural system of memory and pleasure (Veldhuizen et al., 2010). Thus, taste is used to enjoy certain foods, surpassing its primary role of providing energy to our organism. In mycology this behaviour is mainly employed by mycophagous people to appreciate the fruit of their mushroom hunting. However, the sense of taste has not only a physiological and psychological role; it can also be used in field taxonomic identification. [read more]

Cazabonne J. 2022. The Use of Humans Senses in the Identification of Mushrooms part 2: touch. Field Mycology, 23 (4): 118 – 122. Link.

Preview: After observing a mushroom of interest through your sense of vision and the appropriate use of colours, the next reflex is to collect it and appreciate the shape, texture, and size of the different morpho-elements that make up the fruitbody. Our ability to distinguish different shapes and textures when handling mushrooms is allowed by numerous cutaneous mechanoreceptors situated in the skin’s layers, especially at the tip of the fingers (Roudaut et al., 2012). Tactile perception is an assemblage of complex neural mechanisms (Johnson, 2001) permitting the detection of both innocuous and noxious mechanical stimuli. This physical sensibility is surprisingly important for the identification of mushrooms. [read more]

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 in detail and illustrate the first collection of Leucopaxillus tricolor (Peck) Kühner from Aveyron (France), carried out in a mixed forest at Agen-d’Aveyron, in August 2021. This species is considered by many authors as rare and is included in red lists of many countries. [lire plus]

Molecular-based Diversity Studies and Field Surveys Are Not Mutually Exclusive: On The Importance of Integrated Methodologies in Mycological Research. Frontiers in Fungal Biology, 3: 860777. http://dx.doi.org/10.3389/ffunb.2022.860777

Abstract: 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 works. Nevertheless, a non-negligible part of the studied funga escaped their attention. Thanks to modern developments in molecular techniques, the study of fungal diversity has been revolutionized in terms of tools and knowledge. Despite a number of disadvantages inherent to these techniques, traditional field-based inventory work has been increasingly superseded and neglected. This perspective aims to demonstrate the central importance of field-based research in fungal diversity studies, and encourages researchers not to be blinded by the sole use of molecular methods.

(1-4): 85 99. Link.

Résumé: 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 description et des photographies macro-et microscopiques de la récolte sont données. La position phylogénétique de cette espèce, basée sur les marqueurs ITS et 28S, est présentée et les espèces les plus proches sont comparées. Cette analyse moléculaire montre que notre récolte s’apparente à Mycena discobasis et met aussi en évidence la difficulté de délimiter les espèces de mycènes de la section Exornatae. Abstract: The rare Mycena chlorinosma Singer (Agaricales, Mycenaceae) was found during a mycological inventory work in the ‘bois de Pouciquot’, located on the campus of the University of Toulouse (France). This collection is the 8th known mention of this species in France (mainland and overseas), and the 3rd mention in the French mainland. A description and macro-microphotographs of the collection are given. The phylogenetic position of this species, based on the ITS and 28S markers, is presented and the closest species are compared. This molecular analysis shows that our collection is related to Mycena discobasis and put forward difficulties with species delineation in Exornatae section. [lire plus]

Preview: 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 in situ is difficult, but remembering it is even more so. When identifying a fungus in the field, four of our five senses are mainly involved: touch, smell, taste, and sight. Hearing does not help in direct identification of the fungus. In this series of articles, the role and importance of these four senses in identifying a fungus are non-exhaustively reviewed.

from Aveyron (France ). Carnets Natures, 8: 67 81. Link.

Abstract: 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 taxon was reported: Latin name, author(s), Basionym, locality (if known) and record sources. Macrophotographs of some new records are also appended. This work is a contribution to the knowledge of myxomycetes of Aveyron, which will eventually be integrated into a national checklist project of French myxomycetes.

Au total, 21 espèces représentant 14 genres, 7 familles et 5 ordres, ont été listées, grâce aux données collectées par l’Association Mycologique et Botanique de l’Aveyron (AMBA) et à un travail de recherche bibliographique. Les informations suivantes pour chaque taxon ont été indiquées : nom latin, auteur(s), basionyme, localité (si connue) et les références. Des macrophotographies de quelques nouveaux taxa aveyronnais sont aussi annexées. Ce travail est une contribution à la connaissance des myxomycètes d’Aveyron, qui sera éventuellement intégré à un projet de checklist nationale des Myxomycètes de France. [read more]

Aperçu: En Abitibi-Témiscamingue, les forêts boréales sont des éléments clés en termes de superficie et de valeur économique. En effet, le bois est utilisé pour la production de chaleur, de papier ou pour la construction. Une grande partie du territoire est recouverte par la ceinture d’argile. Cependant, des “crêtes” se distinguent au sein de cette matrice argileuse. Appelées “eskers”, ces formations géologiques sont apparues lors du retrait des glaciers à la suite de la dernière glaciation. Ces glaciers ont laissé sur leur passage des ensembles de gravier et de sable , nommés “dépôts fluvioglaciaires”. [lire plus]
