“…Interestingly, B. anceps is the only European species of Biscogniauxia known to have bicellular (two-celled) ascospores with typical dark colored and hyaline cells. This feature is considered neotenic [ 31 ], which indicates that sexual maturity and reproduction of the organism is attained by the retention of juvenile characteristics, represented by the presence of hyaline germinable ascospores. Despite such morphological distinctions between B. nummularia and B. anceps , a recent rDNA phylogenetic analysiss suggested that these two species belong to the same evolutionary clade [ 32 ] and, therefore, the only two fungal taxa to be retained within genus Biscogniauxia , thus far.…”

“…Stukenbrock [ 47 ] have addressed this phenomenon in relation to asexual fusion in fungi and the role of hybridization in evolution and emergence of new fungal plant pathogens. Interestingly, Rogers et al, (1996) have pointed out that B. anceps is taxonomically unsettled, due to its neotenic situation, exemplified by the reversion of ascospores to a more juvenile or ancestral condition [ 31 ]. It appears that Biscogniauxia sp.…”

Natural Fungicolous Regulators of Biscogniauxia destructiva sp. nov. That Causes Beech Bark Tarcrust in Southern European (Fagus sylvatica) Forests

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.

Three new genera, six new species, three combinations, six epitypes, and 25 interesting new host and / or geographical records are introduced in this study. New genera: Neoleptodontidium (based on Neoleptodontidium aquaticum), and Nothoramularia (based on Nothoramularia ragnhildianicola). New species: Acremonium aquaticum (from cooling pad water, USA, Cladophialophora laricicola (on dead wood of Larix sp., Netherlands), Cyphellophora neerlandica (on lichen on brick wall, Netherlands), Geonectria muralis (on moss growing on a wall, Netherlands), Harposporium illinoisense (from rockwool, USA), and Neoleptodontidium aquaticum (from hydroponic water, USA). New combinations: Cyphellophora deltoidea (based on Anthopsis deltoidea), Neoleptodontidium aciculare (based on Leptodontidium aciculare), and Nothoramularia ragnhildianicola (based on Ramularia ragnhildianicola). Epitypes: Cephaliophora tropica (from water, USA), Miricatena prunicola (on leaves of Prunus serotina, Netherlands), Nothoramularia ragnhildianicola (on Ragnhildiana ferruginea, parasitic on Artemisia vulgaris, Germany), Phyllosticta multicorniculata (on needles of Abietis balsamea, Canada), Thyronectria caraganae (on twigs of Caragana arborescens, Ukraine), and Trichosphaeria pilosa (on decayed Salix branch, Netherlands). Furthermore, the higher order phylogeny of three genera regarded as incertae sedis is resolved, namely Cephaliophora (Ascodesmidaceae, Pezizales), Miricatena (Helotiales, Leotiomycetes), and Trichosphaeria (Trichosphaeriaceae, Trichosphaeriales), with Trichosphaeriaceae being an older name for Plectosphaerellaceae.

“…Stroma was descripted as two layers of " oor stroma" and "roof stroma" by Gregory et al (1951). Pirozynski (1974) Vivantia was accepted in the Amphisphaeriaceae to include species with features of bipartite, carbonaceous, applano-pulvinate stromata, cylindrical asci with apical ring bluing in Melzer's reagent and two-celled, subhyaline ascospores without germ slit (Rogers et al 1996). Two-layers, carbonaceous stromata and Nodulisporiurn anamorphs indicate its a nity with Biscogniauxia.…”

Three species possessing characteristics of Graphostromataceae were observed in China. Morphology of the described species with illustrations and their phylogeny based on regions of internal transcribed spacers (ITS), the second largest subunit of the RNA polymerase II (RPB2), β-tubulin (TUB2) and α-actin (ACT) are provided. Two new species and one new record from China were identified. Morphologically, Biscogniauxia glaucae sp. nov. differs from B. atropunctata var. maritima, B. citriformis var. macrospora, B. fuscella and B. mediterranea by its stromata with raised margins, with clear outlines, with punctate ostioles openings and ascospores which are equilateral with broadly rounded ends, with a straight germ slit on the more concave side, nearly full spore length, lacking appendages and sheathes. ITS sequence difference between Graphostroma guizhouensis sp. nov and type strain of G. platystomum is 7%, which support identifying it as a new species. Camillea broomeana with scanning electron microscope description of ascospores was illustrated as a new record from China. Cryptostroma was proposed in Graphostromataceae based on molecular data. Vivantia was accepted in Graphostromataceae based on its morphological characteristics and Nodulisporiurn anamorphs which is similar with that of Biscogniauxia.
