Where to find. How do I get the Lingzhy / Reishi and how you can get it too.

There is plenty of Reishi mushroom online , generally in capsule form and containing the mushroom and spores. Most likely, the industry is settle  in Asia, where the species is cultivated and revered.
I haven't tried them but I read the label, and  the amount of Ling zhi in the capsules are not much

While you can find generic ling zhi, not the extract part  anywhere from  USD 25 to 35  in a bottle of 60 capsules.  It is best is to take the extract to get the full of it. A bottle of 120 capsules, of  the extract is more concentrated and the dosage and purity is higher.There is a very reputable vendor in China, which cultivates, sells and ships Ling zhi extract, which is very clean and potent and it is what I through know  I after going through cancer therapy, started taking it.

The company wants to enter the U.S market and in order to do so, relied in MLM marketing.
I did not at first looked into the MLM marketing array when I started to tale Reishi mushrooms, I did it out of necessity but ends up that this is a second good idea.

If you want to be part of the MLM and take Reishi, go to this site I want you to heap the same benefits I am having from it.  Since I consume, why not market it too? Upfront, the extract is not 35 a bottle, it is more. But if you are willing to try it, you will benefit from it both ways. 

Or there is a third alternative , you can also go on and search for Reishi/ Ling zhi Mushrooms in nature.
This is how it looks like:

Characteristics

 Ecology:

Saprotrophic, meaning it feeds on dead organic matter. Look for them on dead or dying trees and old stumps or logs.

Habitat:

Grows on hardwood stumps and logs including oaks, elms, beeches, maples, and more. The tsugae species seems to prefer conifers, mainly hemlocks (tsuga means hemlock).

Cap:

Kidney or fan-shaped and reddish with a wet, lacquered appearance when young. The shiny, reddish cap is one of the main identifying features of reishi mushrooms. As they age the flesh becomes tougher and spores drop. Air currents often blow these spores to the top of the mushroom, dulling its shiny cap.

The cap rarely gets larger than a foot across and an inch or two thick. It may or may not be attached to a stem.

The newest growth often shows up as a whitish edge. A main difference between the two species is that Ganoderma lucidum has a more brownish flesh color and Ganoderma tsugae has whiter flesh (see pictures below).

Reproduction:

Spores come out of tiny pores on the underside of the mushroom rather than gills. This is why they're known as polypores (poly means "many").

Spore print:

Brown in both species.

Range:

Ganoderma lucidum prefers warmer regions and is found in many parts of Asia, Australia, South America, Southern Europe, and the Southeastern United States. Ganoderma tsugae likes colder temperatures, and can be found as far as the Northeastern United States.

Time of year:

Summer to fall for all species.
