Rhizopogon vinicolor is a species complex of ectomycorrhizal fungus which forms a mutualistic relationship with the Douglas-fir (Pseudotsuga spp.). The species was first described scientifically by American mycologist Alexander H. Smith in 1966.[1]
A number of species of Rhizopogon are morphologically similar and they are collectively known as the R. vinicolor species complex. A phylogenetic investigation of R. vinicolor, R. diabolicus, R. ochraceisporus, R. parvulus and R. versiculosus was published in 2002. It was determined that they separated into two distinct clades, R. vinicolor and R. versiculosus.[2]
Characteristics
The fruit bodies of R. vinicolor are produced underground. They are 10 to 33 millimetres (0.4 to 1.3 in) in diameter, rounded or irregularly shaped, of a dirty white colour, later red, and with a few rhizomorphs at the base. The peridium is a single layer, becoming wine-red when exposed. The gleba is firm and buff coloured, darkening with age, with small labyrinthine locules. The trama are well-filled with basidiospores. These are elliptical to ovoid, 5–9 × 3–5 μm, do not have a septum and are smooth and hyaline. The mycelial cords are few in number or absent altogether.[3][4]
