Weeping merula (building cancer)

Weeping merula, or more commonly known as building cancer, is a fungus that is increasingly common in Quebec. It is most often found in dark, poorly ventilated, damp places such as crawl spaces. Do you think your home could be invaded by weeping merula? It’s possible, since the number of cases is growing in Quebec.

When mature, weeping merula resembles a thick, brownish-orange crust. However, when the fungus is immature, it appears as a whitish filamentous layer of varying thickness. As other fungi can resemble it, identification of weeping merula by a qualified microbiologist is essential.

This Asian fungus can wreak havoc in buildings. The weeping merle, or Serpula lacrymans as it is known in Latin, is a fungus capable of rapidly decomposing the wood of building frames. Building cancer, as some call it, can spread throughout a home, and it’s not uncommon to see the invasive fungus on brick, plastic membranes or concrete.
