Following the media coverage of some recent cases of dry rot (Serpula lacrymans) house contamination, we examine its historical prevalence in Canada based on data from Natural Resources Canada’s mycological herbaria and culture collections in comparison with that reported from Europe and the United States. Based on the knowledge developed in Europe on dry rot, we describe its biology, its detection, the prevention of S. lacrymans contamination and the restoration of contaminated buildings according to the rules and regulations in effect in Québec and Canada.
Plain Language Summary
In this study, the researchers take a look at the history of the presence of dry rot fungus, Serpula lacrymans, in Canada and propose measures to fight it. This fungus, which consumes wood, is found almost exclusively in buildings, where it causes significant decay. It is considered the most destructive and difficult to control of all fungi found in buildings.
To carry out this study, the researchers compared data from mycological herbaria and from culture collections belonging to Natural Resources Canada to data sourced from Europe and the United States. Based on the knowledge developed in Europe regarding Serpula lacrymans, the researchers were able to describe its biology, methods for detecting its presence and preventing infestations, as well as methods for restoring affected buildings that are in accordance with the regulations in force in Canada and Quebec.
