- Mycelium (Wikipedia)
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in Armillaria.
- Cottonwood Island Wildlife Area Unit (wdfw.wa.gov)
The Cottonwood Island Unit is a unique forested property that is representative of a historic habitat type that would have been more widespread along the lower Skagit River Valley. It provides valuable mature cottonwood forest habitat for a variety of forest birds and raptors, primarily buteos and eagles. The remnant of Cottonwood Slough also provides off-channel habitat for salmonids during certain times of the year and has been evaluated for potential habitat restoration projects.
