Leucocoprinus birnbaumii
species of fungus
Leucocoprinus birnbaumii, commonly known as the flower pot parasol, yellow parasol, flowerpot parasol, or plantpot dapperling, is a species of gilled mushroom in the family Agaricaceae. It is common in the tropics and subtropics. In temperate regions, it frequently occurs in greenhouses, flowerpots, and indoor terrariums. It is toxic if ingested.
Taxonomy
The species was first described as Agaricus luteus in 1788 by the English mycologist James Bolton who described an observation from a hothouse near Halifax, three years earlier in 1785. Bolton also provided an illustration of the mushrooms. At the time gilled species were classified as Agaricus and luteus comes from the Latin for yellow or yellow-orange. Bolton suggested the common name of "Yellow Cottony Agaric" in reference to the soft, scaly texture of the mushroom.
However the name A. luteus had already been used to describe an unrelated Russula species and was published in 1778 by William Hudson so Bolton's A. luteus was illegitimate.
Nonetheless Agaricus luteus continued to be used and in James Sowerby's 1796 book entitled Coloured figures of English fungi or mushrooms his description of Agaricus cepaestipes (now Leucocoprinus cepistipes) also includes A. luteus and A. cretaceus (now Leucocoprinus cretaceus) which he considered to be "undoubtedly the same species", only differing in colour.
The public source identifies “Leucocoprinus birnbaumii” as species of fungus. This brief keeps that definition visible, then builds a research path around Leucocoprinus, birnbaumii and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Leucocoprinus birnbaumii”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q1393937. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1788, 1785, 1778 and 1796.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
