Note: | This species had been described by Murrill (1938) as Ceriomyces aureissimus which was certified to B. auripes by Singer(1947). However Murrill recognized that B. auripes was a mere synonym of B. edulis. But the latter with context white and stipe not yellow is distinct from the former. | |||
