[4] Leucocoprinus flavescens is a small mushroom with very thin white to pale yellow flesh.

Ovoid to campanulate (bell shaped) with an umbo before flattening or becoming convex with age.

[5][4] In a 1907 study Morgan documented Lepiota flavescens growing on the ground under Robinia and Gleditsia trees in Southern Ohio[3] whereas Smith documented the species from greenhouses in Southern California and Massachusetts.

[4] It has also been documented in Illinois[5] and in 2010 it was recorded in Washington state where it was found growing in large clusters in a covered outdoors container filled with potting soil intended for a greenhouse.

It is likely that it is often misclassified as other Leucocoprinus species which are simply more well known or more commonly suggested by identification algorithms used by the public such as iNaturalist.
