Leucocoprinus antillarum is a species of mushroom producing fungus in the family Agaricaceae. [1] [2]
It was described in 2021 by the mycologists Alfredo Justo, Claudio Angelini and Alberto Bizzi who classified it as Leucocoprinus antillarum. [3]
Leucocoprinus antillarum is a small dapperling mushroom with thin flesh.
Cap: 3.5-4.5 cm wide starting ovate before expanding to conical-campanulate and then flattening to convex or plano-convex. Finally developing a slight depression with maturity with or without a small umbo. The surface is completely white with velvety scales when immature but the umbo develops a brownish-ochre or yellowish-ochre colour as it matures and white to brownish-grey or ochre fibrillous scales are scattered sparsely across the rest of the cap surface, becoming sparser towards the margins. The surface background remains white but with a pinkish-grey tint around the centre fading to white towards the margins, which have striations that reach around halfway up the cap surface. Gills: Free, fairly crowded and white. Stem: 4.5–6 cm tall and 2.5-5mm thick and cylindrical with an only slightly wider base. The surface is whitish with white fibrillose scales on the bottom half and white rhizomorphs at the base. The ascending, membranous stem ring is white but sometimes develops a greyish-ochre edge. Spores: Ovoid to amygdaliform without a germ pore. Dextrinoid and metachromatic. (5) 5.5-7 x 3.5-5 (5.5) μm. Basidia: 15-27 x 8.12 μm.Smell: Indistinct. [3]
The specific epithet antillarum derives from the Antilles in which the species was found. [3]
The species was discovered in the Dominican Republic where it grows gregariously on the ground amongst leaf litter in deciduous woodland in August to January. Phylogenetic data has also suggested that the species is present in Brazil, Panama and Guadeloupe based on comparison with other specimens collected. [3]
These similar Lepiota species may actually be Leucocoprinus or Leucoagaricus species that have yet to be reclassified. [3]
Leucocoprinus brebissonii is a species of mushroom producing fungus in the family Agaricaceae. It is commonly called the skullcap dapperling due to its distinctive pattern on the cap. This mushroom was only thought to be found in Europe but it has since been observed in the Pacific Northwest. Like many other Leucocoprinus species though it is also documented from plant pots and greenhouses which means it may have a worldwide distribution in captivity.
Leucocoprinus straminellus is a species of mushroom producing fungus in the family Agaricaceae. Like other Leucocoprinus species it may have originated in a tropical climate but now finds a home in plant pots, greenhouses and compost piles in many countries. Leucocoprinus straminellus is described as being similar to the more commonly known Leucocoprinus birnbaumii but it is smaller and a lighter shade of yellow with smaller spores that lack a germ pore. It is also described as being superficially similar to Leucocoprinus fragilissimus but slightly more robust with flesh that is less translucent.
