Rhizopogon amylopogon is a sub-genus of Rhizopogon containing seven species.
[1] Sub-genus Amylopogon are ectomycorrhizal fungi categorized as monotropoid mycorrhiza.
[2] These fungi are characterized by the presence of a mantle, Hartig net, unique fungal peg, and intracellular hyphal complexes.
[3] They are also classified by a specific and obligate symbiosis with members of Monotropoideae through a process known as myco-heterotrophy.
[1][4][5] Monotropoideae species depend on Amylopogon fungi for carbon which they in turn acquire from members of Pinus in a host specific tripartite Hartig net exchange.
