Résumé :
Dead wood is an important habitat for both fungi and insects, two enormously diverse groups that contribute to forest biodiversity. Unlike the myriad of studies on fungus–insect relationships, insect communities on ascomycete sporocarps are less explored, particularly for those in hidden habitats such as underneath bark. Here, I present my observations of insect community dynamics on Biscogniauxia spp. on oak dead wood from the early anamorphic stage to matured teleomorph stage, aided by the debarking behaviour of squirrels probably targeting on these fungi. In total, 38 insect taxa were observed on Biscogniauxia spp. from March to November. The community composition was significantly correlated with the presence/absence of Biscogniauxia spp. Additionally, Librodor (Glischrochilus) ipsoides, Laemophloeus submonilis, and Neuroctenus castaneus were frequently recorded and closely associated with Biscogniauxia spp. along its change from anamorph to teleomorph. L. submonilis was positively associated with both the anamorph and teleomorph stages. L. ipsoides and N. castaneus were positively associated with only the teleomorph but not with the anamorph stage. N. castaneus reproduced and was found on Biscogniauxia spp. from June to November. These results suggest that sporocarps of Biscogniauxia spp. are important to these insect taxa, depending on their developmental stage.

Résumé :
The genus Biscogniauxia is paraphyletic to members of the family Xylariaceae and includes at least 52 species to date that are mainly pathogens of dicotyledonous angiosperm trees. Most of these are forest trees, such as those in the genera Acacia, Acer, Alnus, Eucalyptus, Fraxinus, Populus, and Quercus, and other species of minor importance. Biscogniauxia spp. have been reported as endophytes or secondary invaders that attack only stressed plants. During a survey in rosaceous orchards in southern Italy, several charcoal cankers were observed and stroma samples were collected. A collection of 31 Biscogniauxia isolates was analyzed. Their phylogenetic relationships were determined through study of the internal transcribed spacer, β-tubulin, and actin gene sequences. Combining morphological, cultural, and molecular data, a new species of Biscogniauxia is described here as Biscogniauxia rosacearum. This new species was isolated for the first time from rosaceous hosts in Apulia. Pathogenicity tests showed that it causes symptoms on stems when artificially inoculated and produces stromata on the bark surface.

Résumé :
Mycoparasites are a collection of fungicolous eukaryotic organisms that occur on and are antagonistic to a wide range of plant pathogenic fungi. To date, this fungal group has largely been neglected by biodiversity studies. However, this fungal group is of interest, as it may contain potential biocontrol agents of pathogenic fungi that cause beech Tarcrust disease (BTC), which has contributed to the devastation of European beech (Fagus sylvatica) forests. Biscogniauxia nummularia has been demonstrated to cause BTC. However, a trophic association between mycoparasites and pathogenic Biscogniauxia spp., has not been established. This study aimed to taxonomically identify and characterize Biscogniauxia, a fungus causing destructive BTC disease in European beech at Lovćen national park, Montenegro and to uncover the diversity of mycopathogens that are natural regulators of xylariaceous Biscogniauxia stroma formation, associated with beech decline. This finding is supported by distinctive phylogenetic and evolutionary characteristics, as well as unique morphological-microscopic fungal features indicating that Biscogniauxia from Montenegro, which is a major cause of BTC occurring in ancient beech forests at the edge of southern Fagus sylvatica distribution, may be described as a novel fungus specific to Fagus. Its evolutionary nuSSU–complete ITS–partial nuLSU rDNA phylogeny indicates its likely emergence by asexual fusion or introgressive hybridization between diverged B. nummularia and B. anceps species. The name Biscogniauxia destructiva is proposed for the novel fungus, as it is aggressive and highly destructive BTC disease.

Résumé :
Biscogniauxia nummularia (Bull.) Kuntze is a fungus which induces strip-cankers on beech, commonly referred to as charcoal canker. The symptoms of infection are visible on the host tree’s bark as elongated, blackish bark lesions on the trunk and branches. Recent years have shown that, due to climate change causing local epidemics, the species is increasing its economic impact in Mediterranean regions. Until recently, B. nummularia was considered rare and uncommon in central Europe. However, in the last few years it has been noticed more often, mostly in coniferous trees, which are out of B. nummularia’s host range. A similar situation has been observed with the closely related species Biscogniauxia mediterranea (De Not.) Kuntze, which prior to 2017 had not been observed in central Europe at all. This study shows the genetic diversity of mid-European strains of Biscogniauxia spp. (based on the ITS, TEF1, TUB2 and ACT regions) and, as the first in Europe, presents a molecular investigation of this species isolated from coniferous trees. It is also the first attempt at estimating the potential impact of this pathogenic fungus on European forestry management in the close future.

Résumé :
In July 2010, extensive decline of English ash (Fraxinus excelsior L.) was observed near Chiusi della Verna, Tuscany, in central Italy (altitude 956 m a.s.l.; lat. 43° 41′ 54″ N, long. 11° 56′ 9″E). The symptoms on the tree trunks and leaves included lengthwise bark cracks, detached bark, withering of the crown where the bark was detached, and extensive microphyllia. In September 2010, perithecial stromata were observed in the parts of the tree that had lost their bark. They were applanate and black and fruiting bodies were recognized as Biscogniauxia mediterranea (De Not.) Kuntze (basionym Sphaeria mediterranea (De Not.), Ascomycotina, Xylaraceae), a fungus causing charcoal canker that attacks oaks, Acer spp., Castanea sativa Miller, Fagus sylvatica L., and Platanus acerifolia Willd. The biometric characteristics of 30 stromata were examined. The stromata were slightly convex, ellipsoid, and elongate, 7.2 to 20.5 × 3.5 to 4.2 cm. The perithecia were ovoid to tubular, 0.74 to 0.80 × 0.12 to 0.15 mm; the asci were short and stipitate, 7.9 to 10.0 × 120.2 to 170.4 μm. The ascospores were ovoid, brownish-black, with narrowed and roundish ends, 6.9 to 9.1 × 14.6 to 20.0 μm. Colonies grown on PDA at 25°C for 5 days were grey viewed from the top and black viewed from the dish underside. A comparison with the data in the literature (1) confirmed the macro- and microscopic identification. Traditional identification was further confirmed by sequence information from the rDNA ITS region. A BLAST search of the ITS sequence of our B. mediterranea isolate (GenBank Accession No. JX262798) revealed an exact match (100%) with several reference sequences of the fungus present in the database, mainly from oak hosts. Four branches each of five English ash trees growing in a natural environment were inoculated at the trunk junction with a 10–5 ml ascospore suspension. Control consisted of a branch per tree inoculated with an identical volume of sterile water only. After 25 days, the bark became detached and after a further 15 days the typical black stromata appeared. The pathogen was reisolated from the lesions, confirming Koch's postulates. No symptoms were observed on control branches, which presented healed wounds. B. mediterranea was first detected in 1986 on Quercus cerris L. and Q. pubescens Willd. in the Circeo natural park in central Italy (altitude 50 m a.s.l; lat. 41° 27′ 55″44 N, long. 12° 53′ 53″52 E). From there it spread north to other parts of the country. All oak species in Italy appear to be susceptible. Its northward expansion is likely associated with the high temperature and water stress that have been affecting the Italian peninsula for the last few years (4). Most recently, B. mediterranea has also been reported on Q. cerris in the Karst region of Slovenia (lat. 45° 43′ 03″7 N, long. 13° 45′ 20″ 4 E). This confirms its current spread to the more northerly territories, most likely because of ongoing changes in the climate that are creating optimal conditions for its survival in areas that were previously unsuitable to it.

Résumé :
Charcoal canker, caused by the fungus Biscogniauxia mediterranea, is one of the most frequent diseases of cork oak in Portugal. The pathogen has been considered a secondary invader that attacks only stressed hosts; however, in recent years, an increasing number of young trees exhibiting the disease symptoms have been recorded. A collection of monoascosporic cultures isolated from single stromata of B. mediterranea in cork oak from different locations was analyzed by means of microsatellite—Primed Polymerase Chain Reaction—using three microsatellite primers, in order to detect the genetic variation of the population thus discussing its plasticity and ability to adapt to different conditions. The results showed a high level of genetic variability among isolates obtained from the same stroma, being impossible to distinguish isolates from individual stromata neither from different geographical location.

Abstract A taxonomic study of Nemania Gray, Entoleuca Syd. and Euepixylon Füisting (= Nemania s.l.; Xylariaceae) was carried out for the Nordic countries: Norway, Sweden, Finland and Denmark. No species of Nemania have been found in the remaining Norden: Iceland and the Faeroes. Fourteen species of Nemania s. str. were found in the area: Nemania aenea, N. aureolutea comb. n., N. atropurpurea, N. carbonacea, N. chestersii, N. colliculosa comb. n., N. con.fluens, N. diffusa, N. effusa, N. prava n. sp., N. reticulata comb. n., N. serpens, and two unknown species (Nemania spp. A and B) not formally described because of scanty material. In addition the two split-outs fromNemania, Entoleuca mammata andEuepixylon udum, are treated. A dichotomous key has been prepared and the species are reviewed alphabetically with comments on taxonomy, ecology and chorology. All species have been drawn, photographed and mapped. In addition to conventional taxonomic procedures, a selection of species from Nemania s.l., Biscogniauxia and Hypoxylon were subjected to an ITS nrDNA sequencing study. This study supported the delimitation of taxa as defined in this work, and confirms Nemani a as different from Hypoxylon and Biscogniauxia. Four EuropeanNemania taxa are still unknown in Norden: Nemania gwyneddii (Whalley, R.L. Edwards & S.M. Francis) Pouzar, N. illita (Schwein.) Pouzar, Nemania serpens (Pers.: Fr.) Gray var. macrospora (J.H. Mill.) Pouzar. The fourth taxon, Hypoxylon terricola J.H. Mill. certainly also belongs to Nemania.

Symptoms of the disease (presence of exudate and wounds with stroma) caused by the fungus have been found on stems and branches of cork oak in Maleshevska Mountain. Harvesting of cork does not visibly affect the phytosanitary status of the trees. A significantly higher risk of parasitic fungus development occurs in coppice-managed crops where it causes the death of young trees. The associations of ten insect species with the Quercus suber are new for Bulgaria. Eight of them are possible vectors of the fungus.

Résumé :
Coffee endophytes have been studied for almost 74 years, and several studies have demonstrated coffee-endophytic fungi with antibacterial and antifungal potential for human and plant pathogens. In this study, we isolated and identified a total of 235 strains of endophytic fungi from coffee leaf tissues collected in four coffee plantations in Pu’er city, Yunnan province, China. Molecular identification was carried out using maximum likelihood phylogenetic analysis of nuclear ribosomal internal transcribed spacer (ITS1-5.8S rDNA-ITS2) sequences, while the colonization rate and the isolation frequency were also calculated. Two pathogenic fungi (Alternaria alternata and Penicillium digitatum) and two pathogenic bacteria (Pseudomonas syringae and Salmonella enterica subsp. enterica) were used for screening the antagonistic activities of 61 strains of coffee-endophytic fungi by a dual-culture test assay while maximum likelihood phylogenetic analysis confirmed their natural classification. This is the first study of coffee-leaf-endophytic fungal diversity in China, and the results revealed that coffee-endophytic fungi from this study belong to the Ascomycota, distributed among two classes, 10 orders, and 17 families. Concurrently, endophytic fungi isolates distributed in Arthrinium, Biscogniauxia, Daldinia, Diaporthe, and Nigrospora showed strong antagonistic activities against the pathogens. For the pathogens Alternaria alternata and Pseudomonas syringae, Nigrospora XCE-7 showed the best inhibitory effects with inhibition rates of 71.76% and 61.11%, respectively. For the pathogen Penicillium digitatum, Daldinia ME-9 showed the best inhibitory effect with a 74.67% inhibition rate, while Biscogniauxia PTE-7 and Daldinia T5E-1-3 showed the best inhibitory effect with a rate of 60.42% against the pathogen Salmonella enterica subsp. enterica. Overall, our study shows the diversity of coffee endophytes in four coffee-growing areas in Pu’er city, Yunnan province, China, and their potential use as biological control agents against two fungal and two bacterial pathogens.

Résumé :
An increase in cork oak diseases caused by Biscogniauxia mediterranea and Diplodia corticola has been reported in the last decade. Due to the high socio-economic and ecologic importance of this plant species in the Mediterranean Basin, the search for preventive or treatment measures to control these diseases is an urgent need. Fungal endophytes were recovered from cork oak trees with different disease severity levels, using culture-dependent methods. The results showed a higher number of potential pathogens than beneficial fungi such as cork oak endophytes, even in healthy plants. The antagonist potential of a selection of eight cork oak fungal endophytes was tested against B. mediterranea and D. corticola by dual-plate assays. The tested endophytes were more efficient in inhibiting D. corticola than B. mediterranea growth, but Simplicillium aogashimaense, Fimetariella rabenhorstii, Chaetomium sp. and Alternaria alternata revealed a high potential to inhibit the growth of both. Simplicillium aogashimaense caused macroscopic and microscopic mycelial/hyphal deformations and presented promising results in controlling both phytopathogens’ growth in vitro. The evaluation of the antagonistic potential of non-volatile and volatile compounds also revealed that A. alternata compounds could be further explored for inhibiting both pathogens. These findings provide valuable knowledge that can be further explored in in vivo assays to find a suitable biocontrol agent for these cork oak diseases.

Résumé :
Plant endophytes are known to alter the profile of secondary metabolites in plant hosts. In this study, we identified the main bacterial and fungal representatives of the wild grape Vitis amurensis Rupr. microbiome and investigated a cocultivation effect of the 14 endophytes and the V. amurensis cell suspension on biomass accumulation and stilbene biosynthesis. The cocultivation of the V. amurensis cell culture with the bacteria Agrobacterium sp., Bacillus sp., and Curtobacterium sp. for 2 weeks did not significantly affect the accumulation of cell culture fresh biomass. However, it was significantly inhibited by the bacteria Erwinia sp., Pantoea sp., Pseudomonas sp., and Xanthomonas sp. and fungi Alternaria sp., Biscogniauxia sp., Cladosporium sp., Didymella sp. 2, and Fusarium sp. Cocultivation of the grapevine cell suspension with the fungi Didymella sp. 1 and Trichoderma sp. resulted in cell death. The addition of endophytic bacteria increased the total stilbene content by 2.2–5.3 times, while the addition of endophytic fungi was more effective in inducing stilbene accumulation by 2.6–16.3 times. The highest content of stilbenes in the grapevine cells cocultured with endophytic fungi was 13.63 and 13.76 mg/g of the cell dry weight (DW) after cultivation with Biscogniauxia sp. and Didymella sp. 2, respectively. The highest content of stilbenes in the grapevine cells cocultured with endophytic bacteria was 4.49 mg/g DW after cultivation with Xanthomonas sp. The increase in stilbene production was due to a significant activation of phenylalanine ammonia lyase (PAL) and stilbene synthase (STS) gene expression. We also analyzed the sensitivity of the selected endophytes to eight antibiotics, fluconazole, and trans-resveratrol. The endophytic bacteria were sensitive to gentamicin and kanamycin, while all selected fungal strains were resistant to fluconazole with the exception of Cladosporium sp. All endophytes were tolerant of trans-resveratrol. This study showed that grape endophytes stimulate the production of stilbenes in grape cell suspension, which could further contribute to the generation of a new stimulator of stilbene biosynthesis in grapevine or grape cell cultures.

Résumé :
Urban trees are one of the valuable storage in metropolitan areas. Nowadays, a particular attention is paid to the trees and spends million dollars per year to their maintenance. Trees are often subjected to abiotic factors, such as fungi, bacteria, and insects, which lead to decline mechanical strength and wood properties. The objective of this study was to determine the potential degradation of Elm tree wood by Phellinus pomaceus fungi, and Biscogniauxia mediteranae endophyte. Biological decay tests were done according to EN 113 standard and impact bending test in accordance with ASTM-D256-04 standard. The results indicated that with longer incubation time, weight loss increased for both sapwood and heartwood. Fungal deterioration leads to changes in the impact bending. In order to manage street trees, knowing tree characteristics is very important and should be regularly monitored and evaluated in order to identify defects in the trees.
