In young specimens the cap is yellowy coloured and has numerous fleecy grey patches, by maturity the cap loses most of its yellow tint and looks a duller brown, but often retains the fleecy patches. The cap margin may be paler than the centre and is noticeably grooved. The stem has a fragile grey volva at the base.
