These are all varieties of Reishi mushrooms. I searched a lot but could not find the scientific names for all except for red reishi which is Ganoderma lucidum. Below are the colors and common names for them. I would highly appreciate if anybody can provide the scientific names for these reishi varieties:
Red reishi (akashiba)
White reishi (shiroshiba)
Black reishi (kuroshiba)
Blue reishi (aoshiba)
Yellow reishi (kishiba)
Purple reishi (murasakishiba)
