Concentric rings on cap, flesh white turning yellow when cut, latex white turning bright yellow, abundant. Jay Justice reports this fungus is mycorrhizal with oak. Dr. Methven's annotation above states that the European taxon is NOT the same as the North American taxon. The North American taxon needs to receive a new name. Close examination by Dr. Methven (see annotation above) combined with the 2015 DNA analysis confirmed that this specimen is Lactarius chrysorheus.
