Leucocoprinus zeylanicus
species of fungus
Leucocoprinus zeylanicus is a species of mushroom producing fungus in the family Agaricaceae.
Taxonomy
It was first described in 1847 by the British mycologist Miles Joseph Berkeley who classified it as Agaricus zeylanicus.
In 1891 it was classified as Mastocephalus zeylanicus by the German botanist Otto Kunze, however Kunze's Mastocephalus genus, along with most of 'Revisio generum plantarum' was not widely accepted by the scientific community of the age so it remained an Agaricus.
In 1940 it was reclassified as Leucocoprinus zeylanicus by the Dutch mycologist Karel Bernard Boedijn.

Cap: Around 8 cm wide. Campanulate (bell shaped) with an umbo in the centre and striations at the edges. Gills: Free. Stem: Smooth with a narrow stem ring. Spores: 7.5-9x4.5-6.5 μm.
Begin with the source’s own compact description: “Leucocoprinus zeylanicus” is species of fungus. The dossier treats that line as a proposition to test through Leucocoprinus, zeylanicus and species, not as a finished interpretation.
Why this record matters
The phrase “species of fungus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jan 27, 2026. The linked authority identifier is Q10560191. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1847, 1891 and 1940.
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.
