Leucocoprinus birnbaumii

In greenhouses exists a huge problem nowadays. It has everything to do with Leucocoprinus birnbaumii. This is a fungus that lives in the (potting) soil. This fungus has already caused huge problems in several companies. The fungus is usually latently present in the soil, but circumstances can cause growth of the fungus which results in damage to the plant. This fungus origin is from the (sub)tropical areas, but it feels completely fine in the greenhouses or other areas of that temperature. As nutrition it uses organic material like compost. Several potplant growers have problems with Leucocoprinus birnbaumii right now and it has caused a great amount of damage already.
The fungus makes the ground dry and brittle. Also it makes the soil water repelling so the roots of the plant won’t be able to absorb any water. The fungus also breakes down cellulose. The cell walls of plant will collapse which causes the plant to die. The fungus can develop mushrooms. They have a yellow colour but over time they will turn white as the seeds mature. The diameter of the top is between 2-4 cm. Though, the mushroom is not always present and visible. By severe infection you can see the brittle soil and the white of the fungus in it. If there is a light infection there won’t be any visible symptoms and that is where the big danger is.
