Weeping Cerulean

The weeping merula or more commonly called the building cancer is a fungus that is found more and more often in Quebec. It is mostly found in dark, poorly ventilated and humid places such as crawl spaces.

When mature, weeping merula looks like a thick, orange-brown crust. However, when the fungus is immature, it appears as a more or less thick whitish filamentous layer.

From its Latin name,Serpula lacrymans, the merula is known as a fungus that can rapidly decompose the wood of building frames. It can spread anywhere in a home, and it is not uncommon to see the invasive fungus on brick, plastic membranes or concrete.
