[3] Leucocoprinus subglobisporus is a small delicate mushroom with a very thin and fragile white flesh.

Cap: 1.8-2.5cm wide, ovoid or campanulate (bell shaped) and then flattening or depressing with age with a slight raised umbo in the centre.

The surface is white and covered in tiny pale greyish-red floccose (woolly) scales which are a darker brownish-red towards and at the centre of the cap.

The surface is white and silky with a very fine powdery coating whilst the interior is hollow.

The specimens studied by Hongo were found growing on a refuse heap in Ōtsu in the Shiga prefecture or Japan.
