What causes mycelial growth?

Mycelium grows by releasing enzymes from the hyphal tips of the mycelium to digest the surroundings and then absorb the nutrients. The cells will eventually branch, building a vast, mycelial network in the process. These enzymes guide how the mycelium grows.

How do you manage laminated root rot?

Remove as many infected roots and stumps as possible to avoid inoculation of healthy plants. Cut all infected trees within the disease center and all uninfected trees within 50 ft of the disease center.

How can you tell if root rot is laminated?

Laminated root rot infected area Live trees infected with root disease may display one or more the following symptoms: shortened terminal growth, sparse foliage, small needles, chlorosis (yellowing), and stress cone crops, but frequently they are blown over before significant symptoms develop.

What is the scientific name for laminated root rot?

Phellinus sulphurascens (Pilat) [formerly Phellinus weirii (Murr.) Gilb. Douglas-fir form]

How is Armillaria spread?

Armillaria can survive many years in wood debris like an old stump or root system. New infections occur when healthy roots grow close to diseased roots. Black shoestring-like strands of fungal growth, called rhizomorphs, can spread up to 10 feet from an infected tree or stump to infect healthy roots.

What promotes mycelium growth?

Woodchips & straw work as a great substrate for growing mycelium. Get spawn and break it up, spreading sparingly throughout the wood chips or straw and then water. You should see a fully producing mycelium bed in 9-12 months.

What causes root rot in Douglas?

Laminated root rot (LRR) is the most damaging disease of young-growth Douglas- fir (Pseudotsuga menziesii (Mirb.) Franco) in the Pacific Northwest. Laminated root rot is caused by the fungus, Phellinus weirii (Murr.) Gilb., which survives for 50 years or more in roots after infected Douglas-fir are harvested.

How do Armillaria reproduce?

Most species are found on the ground, but a few, including the honey mushroom (A. mellea), will grow directly on wood. Armillaria grow from a single fertilized white spore and spread vegetatively through hyphae, threadlike filaments of cells that aggregate to form long, cordlike bundles called rhizomorphs.
