Hymenoscyphus fraxineus (ash dieback).
2021Abstract H. fraxineus is an anamorphic fungal pathogen that causes ash dieback. Due to the severity of ash dieback H. pseudoalbidus has been on the EPPO Alert list since 2007. It is not known what caused the emergence of this 'new' disease (NAPPO, 2009). Its spread in Europe is thought to be mainly by ascospores, but infected nursery

ABSTRACTWe investigated the ability of Hymenoscyphus fraxineus mitovirus 1 (HfMV1) to spread in nature through the airborne inoculum of its fungal host, the devastating Hymenoscyphus fraxineus. Eight rotating-arm spore traps were installed to collect the airborne spores (presumably ascospores) of H.

Detection of Airborne Inoculum of Hymenoscyphus fraxineus: The Causal Agent of Ash Dieback
2022The inoculum of H. fraxineus consists mainly of ascospores released from apothecia which are growing on fallen leaves infected during the previous year. The ascospores can be detected in various manners due to their high concentration in the air during the main sporulation season, which corresponds to astronomic summer.

Identification of Hymenoscyphus fraxineus, the causal agent of ash dieback in Slovakia
Biologia, 2015Symptoms of ash dieback have been recorded in Slovakia since 2004. The field sampling was carried out in 2013, included 59 segments of shoots and 10 and more petioles per locality from four localities. The causal agent of ash dieback, the hyphomycete Chalara fraxinea T. Kowalski, was isolated from Fraxinus excelsior L. from seven localities in Slovakia.

Exploring the potential invasiveness of Hymenoscyphus fraxineus in Mediterranean mountains
2017Si descrivono una serie di studi sulla epidemiologia, ecofisiologia e genetica del patogeno invasivo del frassino Hymenoschyphus fraxineus (Chalara fraxinea) svolti nei due focolai appenninici noti, che rappresentano il limite meridionale della distribuzione della malattia in Europa e mirati a capire il potenziale di diffusione del patogeno nelle ...
