The surface is white and powdery or floury with some small bunches of fibrils that are coloured very light brown.

The illustration for this species shows some yellowing at the centre disc and possibly at the gills where they meet the stem although this is not described in the text.

The surface is white and covered in a powdery coating the same as the cap, it is flexible when mature and hollows with age but when immature the stem is in the shape of an elongated bulb.

[3] The specimens studied by Bouriquet were found growing in a large cluster on an old pile of garbage near the agricultural station of Nanisana in Madagascar during December of 1942.

L. cretaceus and other Leucocoprinus species are very versatile saprotrophs which are capable of growing on many different substrates so compost, manure, plant debris or wood are all possible.

The accompanying illustration for this species created by Mare Rabarijaona is captioned 'Leucocoprinus Nanisanae'[3] so it is unclear which name was intended and which was in error.
