Long-term responses in the phenology of Mediterranean macrofungi to climatic changes are poorly documented. Here, we address this issue by comparing the fruiting patterns of 159 fungal species in Southern France between the first half of the 19th century and the first decade of the 21st century. We used a trait-based approach to assess the influenc...
Article
Full-text available
Trees acquire hydric and mineral soil resources through root mutualistic associations. In most boreal, temperate and Mediterranean forests, these functions are realized by a chimeric structure called ectomycorrhizae. Ectomycorrhizal (ECM) fungi are highly diversified and vary widely in their specificity toward plant hosts. Reciprocally, association...
Article
The genus Morchella has gone through turbulent taxonomic treatments. Although significant progress in Morchella systematics has been achieved in the past decade, several problems remain unresolved and taxonomy in the genus is still in flux. In late 2019, a paper published in the open-access journal Scientific Reports raised serious concerns about t...

This is a point-by-point rebuttal of the paper entitled “High diversity of Morchella and a novel lineage of the esculenta clade from the north Qinling Mountains revealed by GCPSR-based study” by Phanpadith et al. (2019), published in the Open-Access journal Scientific Reports (2019, 9:19856). The present critique is published as supplementary to th...
Article
Across the Mediterranean biodiversity hotspot, our knowledge of fungal diversity is still fragmentary, and the eastern part of the basin remains poorly explored. This is particularly the case in Lebanon, where macrofungal diversity has never been subject to molecular-based investigation. A first checklist was published in 1957 and updated in 1996,...
Article
Full-text available
Aim Tuber melanosporum is an ectomycorrhizal (ECM) fungus from Mediterranean transitional ecosystems where ECM trees start to dominate among arbuscular-mycorrhizal (AM) shrubs and herbs (companion plants). Its presence entails the development of ‘brûlés’, where vegetation is scarce for unknown reasons. Current T. melanosporum production comes from...
Presentation
The high profile family of Boletaceae accommodates some truly spectacular ectomycorrhizal fungi, including rare as well as commercially important species widely documented in the temperate latitudes of the northern hemisphere. However, the diversity, distribution, estimated abundance and ecological needs of boletoid fungi in Mediterranean ecosystem...
Article
Fungi fruiting hypogeously are believed to form spore banks in soil especially because some fruitbodies are not removed by animals. However, little is known on the proportion of fruitbodies that are not removed by animals. We took advantage of the brûlé phenomenon, which allows delineation of the mycelium distribution, to assess the proportion of u...

The data presented here was obtained during a decade-long macromycete inventory on the island of Cyprus and is supplementary to the research article “Present status and future of boletoid fungi (Boletaceae) on the island of Cyprus: cryptic and threatened diversity unravelled by ten-year study”. A new, rainfall-based sampling protocol for documentin...
Article
Full-text available
Fungi historically placed in the iconic genera of Boletus, Leccinum and Xerocomus have been the subject of major taxonomic revisions in recent years. Yet, despite all advancements in systematics, boletoid fungi in insular ecosystems remain little explored and our knowledge of their diversity, distribution and abundance in Mediterranean ecoregions i...
Article
Full-text available
Aims While fungi are key drivers of the carbon cycle and obligate symbionts of trees, the link between plant-fungal interactions and landscape vegetation changes has been largely overlooked. Our aim was to test whether a local difference in dominant tree species would shape the composition of soil fungi communities. Methods Fungal communities were...
Article
Full-text available
Plant leaves host species rich communities of foliar endophytic fungi (FEF). Compared to the other compartments of the plant microbiome, FEF diversity is poorly known. Here we document the communities of FEF associated with the endemic Corsican pine Pinus nigra subsp. laricio at three sites across its natural range and examine the effect of forest...
Article
Full-text available
In the Mediterranean, long-term land-use changes have resulted into landscape mosaics composed of very few ancient woodland remnants scattered across extended post-agricultural woodlands. Patches of ancient woodlands are now suffering rapid urban growth that reduces their area and impact their associated biodiversity. Here we use the case study of...
Article
Full-text available
The assessment of the environmental impacts of a project involves the acquisition of information on the presence or absence of protected or threatened species on the concerned site. Many factors will influence their probability of being detected and could potentially bias the representativeness of the results. Despite the important consequences tha...
Article

1. In the context of ongoing global changes, it is crucial to characterize and understand the variation of species distributions. For insects, despite increasing emphasis on conservation issues, evidence of range changes over large spatial and temporal scales remains scarce. 2. We aimed to examine distribution changes of butterflies and dragonflies...
Article
The ectomycorrhizal Tuber melanosporum forms edible fruit-bodies after mating between two haploid parents: a maternal individual, which feeds the fruit-body and colonizes surrounding ectomycorrhizas, and a paternal one hitherto undetected around fruit-bodies. Several other aspects of T. melanosporum ecology remain unclear, such as the formation of...
Article
Objective: The aim of the study was to report the very long-term functional outcomes of artificial urinary sphincter (AUS) in male neurological patients. Material and methods: Male neurological patients diagnosed with stress urinary incontinence due to sphincter deficiency and undergoing AUS (AMS 800(®)) implantation between 1985 and 1992 were e...
Article
Elaphomyces (‘deer truffles’) is one of the most important ectomycorrhizal fungal genera in temperate and subarctic forest ecosystems, but also one of the least documented in public databases. The current systematics are mainly based on macromorphology, and is not significantly different from that proposed by Vittadini (1831). Within the 49 species...
Article
The life cycle of the black truffle (Tuber melanosporum) includes a mating before sporulation: although the species is hermaphroditic, mating turns out to involve parents with very different features, that mostly behave as male or female only, suggesting that this species undergoes forced dioecism.
Article
Purpose: To evaluate the long-term functional outcomes after retropubic tension-free vaginal tape (TVT) placement to treat female stress urinary incontinence (SUI). Methods: From September 1998 to September 2000, we prospectively enrolled all consecutive women in our center suffering SUI caused by urethral hypermobility. All women had a retropub...

Article
1. Characterizing the ecological processes driving the assembly and functional composition of ectomycorrhizal (ECM) fungal communities is an area of active research. 2. Here, we applied a trait-based framework to address whether and how environmental filtering and niche differentiation influence the diversity of ECM fungal enzymatic activities in...
Article
The life cycles and dispersal of edible fungi are still poorly known, thus limiting our understanding of their evolution and domestication. The prized Tuber melanosporum produces fruitbodies (fleshy organs where meiospores mature) gathered in natural, spontaneously inoculated forests or harvested in plantations of nursery-inoculated trees. Yet, how...
Article
Background and aims Orchids are known to be particularly sensitive to environmental changes due to their narrow ranges of secondary successional habitats. Lack of data at the community level limits our ability to evaluate how traits of different species influence their responses to habitat change. Here, we used a diachronic survey of Mediterranean...

A new species, Cyptotrama fagiphila, sp. nov., and a noteworthy species recently described from China, Cibaomyces glutinis, are reported from Europe. Their systematic position was confirmed by DNA sequence analyses of the ITS and partial 28S regions of the nuclear rDNA cistron. Based on these data, an emendation of Rhizomarasmius is also proposed t...
Article
Full-text available
During the last two decades, the unprecedented development of molecular phylogenetic tools has propelled an opportunity to revisit the fungal kingdom under an evolutionary perspective. Mycology has been profoundly changed but a sustained effort to elucidate large sections of the astonishing fungal diversity is still needed. Here we fill this gap in...
Article

Applying early names, with or without original material, to genealogical species is challenging. For morels this task is especially difficult because of high morphological stasis and high plasticity of apothecium color and shape. Here we propose a nomenclatural revision of true morels (Morchella, Pezizales) from Europe and North America, based on m...

Article
It is important to evaluate the loss of biodiversity caused by global changes. In the case of orchids, it is still unclear how long the monitoring duration should be chosen in order to achieve a good compromise between the reliability of the orchid dynamics recorded and sampling duration (e.g. years of monitoring). This study aims to propose a meth...
