Rhizoctonia
Rhizoctonia is a type of fungi. They have long filaments called mycelia and a root like structure consisting of food reserves, called sclerotia. Rhizoctonia species eat through a process called saprotrophic nutrition, as the filaments (mycelia) absorb decayed organic matter through the cell wall. The species may resort to plant pathogeny, meaning that it can sometimes cause crop diseases. Some Rhizoctonia species live on the roots of orchid plants and exhibit a mutually beneficial relationship with them during orchid germination.
