SummaryThe European common ash (Fraxinus excelsior) is currently threatened by a pathogenic fungus, Hymenoscyphus pseudoalbidus, which seems to enter the trees through the leaves. Continuous assessments of 39 clones in Danish field trials have shown that there are significant differences in the susceptibility of clones to the new disease. Interestingly,

AbstractDer weitgehend unbekannte Sekundärmetabolismus des phytopathogenen Pilzes Hymenoscyphus pseudoalbidus wurde mittels der CLSA‐Methode untersucht. Eine Serie flüchtiger Lactone wurde per GC/MS identifiziert. Die Lactone wurden synthetisiert und in einem Bioaktivitätstest eingesetzt, in dem eine der Verbindungen als starker Keimungsinhibitor ...

Abstract Shoot dieback disease of European ash caused by the ascomycete Hymenoscyphus pseudoalbidus threatens ash on a continental scale. A spore sampler placed in a diseased ash forest in Southern Norway, coupled with microscopy and DNA-based fungal species-specific real-time PCR assays, was employed to profile diurnal and within-season variation in

SummaryExamination of isolates of Hymenoscyphus albidus from France revealed that this fungus does not form an anamorphic stage in culture. The lack of an asexual stage in this fungus is a conspicuous morphological difference to the ash dieback pathogen Hymenoscyphus pseudoalbidus, which is associated with its Chalara fraxinea anamorphic state.

Scandinavian Journal of Forest Research, 2014
The invasive fungal pathogen, Hymenoscyphus pseudoalbidus V. Queloz, has decimated stands of Fraxinus excelsior L. over most of the species' natural distribution area. We assessed crown damage from 2009 to 2014 (at ages 8, 11 and 13) in 43 open-pollinated ash families planted in north-eastern Zealand, Denmark, and confirmed the presence of substantial ...

Phytochemistry, 2014
Eight European ash (Fraxinus excelsior) genotypes with different known susceptibility to Hymenoscyphus pseudoalbidus were tested against the phytotoxin viridiol and their response described at the microscopic and metabolomic level. All ash genotypes were sensitive to the toxin and necrosis was detectable after 24h.

Das Triebsterben an Eschen (Fraxinus excelsior) hat einen chronischen bis letalen Verlauf. Es wurden mehr als 160 Isolate des Anamorph von H. pseudoalbidus, ehemals als Chalara fraxinea bezeichnet, charakterisiert. Im Fokus standen die Morphologie der Isolate in Bezug auf makroskopische und mikroskopische Merkmale, sowohl des anamorphen als auch ...
