Observation 10003: Rhizopogon occidentalis Zeller & C.W. Dodge

When: 2002-10-20

Collection location: Cape Lookout State Park, Tillamook Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

Specimen available

Notes: In maturity, Rhizopogon occidentalis can become nearly greenish and waterlogged, especially after several days of heavy rainfall. Typically the peridium is more likely to have bright yellow or off-yellow or orangish rhizomorphs on the peridium, be barely erumpent to 3 inches deep; and form mushrumps visible in sandy soils pushing up piles of Lodgepole pine needles or other duff. R. occidentalis is most frequently found by me (and I admit to collecting quite a bit of it) under Lodgepole pine in either sand dunes or sandy soil conditions along the Northern Oregon coast. I have also collected it a single time near Indian Ford, Deschutes Co., OR under Ponderosa pine.
