types of mycelium?

I've read a little about the two types of mycelium that I see. One is larger and likes like fingers or roots and the other is very cotton like. Do these represent different stages of colonization? What are thier names? Any info at all. I just want to learn all I possibly can. Peace.

Its all mycellium, but when people see the strands or threads they sometimes use the word rhizomorph instead, rhiza being greek for root.

The cottony mycelium is called tomentose and the finger or root like is called rhizomorphic. Most mycelium starts out as cottony and later becomes rhizomorphic. The differences can be age related but there are other important considerations. Mycelium that originates from the germination of a single spore is geneticly incomplete and can not form fruiting bodies. If compatible strands of mycelium from two or more spores grow in close proximity, the strands can join by means of clamp connections. Clamp connections look like rungs on a ladder and the nuclei from one mycelium can flow into the other mycelial tubes by flowing through the clamp connection. These connections bind the strands of mycelium together and it shifts from tometose to rhizomorphic so rhizomorphic strands indicate genetic diversity. It may take the exchanges of nuclei from several different mycelia before the mycelium has pooled enough genetic information to fruit.

Every fruit I've ever cloned gives cottony mycelium. How does this fit into the scheme described? based on: "These connections bind the strands of mycelium together and it shifts from tometose to rhizomorphic so rhizomorphic strands indicate genetic diversity. It may take the exchanges of nuclei from several different mycelia before the mycelium has pooled enough genetic information to fruit. " you'd think clones would be rhizomorphic, right? I don't know much about the science of this, but I know what I've seen with my own agar work. The cover of TMC has a great looking rhizomorphic culture, but I wonder if it really makes a diff. My preference would be to go with a cottony clone from a nice fruit over an isolated rhizomorphic mycelium from a multispore inoculation. If you use a good casing, things go rhizomorphic at that point anyway.
The above information is complete fiction.
