Entoloma subgenus cyanula, informally called the Cyan Entoloma here, is relatively newly researched and there is not a plethora of information on them out there. In recent sightings, cap color ranges from deep indigo/violet to royal blue, and the gill color ranges from white to lilac. Pictured is an image captured by photographer Stu Pickell, @sir.myxo.lot on instagram, of specimens that feature the blue/lilac combo.
