Three specimens under Cistus and Thymus. Pileus 5-6cm, pale yellow, dry, though, glabrous-polished (when cleaned from debris), very bitter taste, no volva or ring or veil (at least not distinct), spore print light cinnamon brown, lamella adnate, stem shiny pale brown. Spores pip-shaped, surface rough (bumpy). IKI inamyloid (cell wall appears dextroid?!).
Am I on the right track if I consider Gymnopilus sp. ?
