25 pen-and-ink illustrations comprised of exactly what the deck's title suggests. The 22 standard major arcana are here in black and white -- but three additional color cards are included, titled "A - The Mycelium", "B - The Hyphae", and "C - The Spore". Privately published by the deck's artist, Christopher Adams, who describes it as follows: "Spawned from a love of all things mycological, and a fascination with the archetypes of the tarot... in the name of the hyphae, the spore, and the holy host."
