Rhizopogon subg. Amylopogon is a subgenus of Rhizopogon containing seven species.
Rhizopogon arctostaphyli Rhizopogon brunsii Rhizopogon ellenae Rhizopogon kretzerae Rhizopogon pinyonensis Rhizopogon salebrosus Rhizopogon subpurpurascens
Subgenus Amylopogon are ectomycorrhizal fungi categorized as monotropoid mycorrhiza.Smith SE, Read DJ (1997) Mycorrhizal symbiosis, 2nd edn. Academic Press, London These fungi are characterized by the presence of a mantle, Hartig net, unique fungal peg, and intracellular hyphal complexes. They are also classified by a specific and obligate symbiosis with members of Monotropoideae through a process known as myco-heterotrophy.THOMAS D. BRUNS and DAVID J. READ (2000) In vitro germination of nonphotosynthetic, myco-heterotrophic plants stimulated by fungi isolated from the adult plants, New Phytology, 148, 335 - 342Bidartendo MI, Bruns TD (2002) Fine-level mycorrhizal specificity in the Monotropoideae (Ericaceae): specificity for fungal species groups. Mol Ecol 11:557–569 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.
