[5] Leucocoprinus viridiflavus is a small dapperling mushroom with thin yellow flesh (up to 4mm thick at the central disc) that discolours olive or green when damaged or cut.

The surface colour is greenish-yellow or sulphur-yellow and is coated in thin dark green patches and specks which may appear sticky when moist or shiny when dry.

The surface is greenish-yellow or sulphur-yellow similar to the cap and is fibrillose with dark green fibers towards the base.

The cap edges do not have striations and are incurved when young, becoming straight with age sometimes with veil fragments present.

The surface is pastel yellow and smooth but with fibers towards the base whilst the interior is solid at first but hollowing with age.

The specimens described by Petch were found on the ground in flower beds in Peradeniya, Sri Lanka[3] whilst the specimens described by Kumar and Manimohan were found in Kerala state, India where they were scattered or solitary on soil amongst decaying Acacia leaves.

It was noted as appearing regularly around the Calicut University campus immediately after heavy rains during dry periods.
