Myxomycetes disease of Pleurotus ostreatus

The myxomycete colony of Pleurotus ostreatus is white, and the vegetative growth stage is mostly feathery, which is generally difficult to distinguish from the hyphae of Pleurotus ostreatus. In the middle and later stage of the growth of Pleurotus ostreatus, the myxomycetes developed rapidly. When the humidity of the mushroom bed was high, the slime molds spread from the bottom of the culture material to the surface, and began to appear bright orange viscose filaments on the surface of the mushroom bed, followed by the rapid production of powdery viscose masses, that is, the myxomycetes spores entering the reproductive stage. The viscose mass quickly spread from the stalk of Pleurotus ostreatus to the lid, and gradually wrapped all the fruiting bodies so that the fruiting bodies rotted and lodged. The myxomycete disease of Pleurotus ostreatus is harmful to the mushroom bed and destroys the culture material, so that the surface of the bed can not produce mushroom or be infected by it, and the culture material and fruiting body rot and deteriorate, especially when Pleurotus ostreatus is cultivated in the open field, the disease is more common, and the damage is serious.

Pathogen Physaraceaesp. It is called follicular slime mold, which is a kind of low-grade bacteria. Its characteristic is that the vegetative body has no cell wall and has a deformable structure or protoplast. When it enters the reproductive stage to form a fruiting body, it is fixed in shape and forms a cell wall, and produces a large number of round or oval spores, different kinds of slime molds.
