Leucoagaricus flavus is a species of mushroom-producing fungus in the family Agaricaceae. [1] [2]
It was described in 2022 by the mycologists Phongeun Sysouphanthong and Naritsada Thongklang who classified it as Leucoagaricus flavus. [3]
Leucoagaricus flavus is a small dapperling mushroom with thin (2mm thick) white flesh.
Cap: 1.5–2 cm wide, umbonate and expanding to flat or plano-convex with a slight umbo. The surface is pale yellow with a fibrillose yellow coating that may peel to reveal a whitish to pale yellow background whilst the centre umbo is smooth with a slightly more pronounced yellow tone.The cap margins are straight and fibrillose with the fibrils being of the same colour as the centre, sulcate striations and fringes are present when mature. Gills: Free, slightly crowded and pale to pastel yellow. They are up to 1.5mm wide, have an eroded edge and bulge in the middle (ventricose). Stem: 3-3.5 cm long and 3-5mm thick, cylindrical or tapering upwards slightly from the wider base. The surface is yellowish-white with a fibrillose or soft, hairy coating of the same colour and the interior is hollow with white fibrils inside. The stem ring is located towards the middle of the stem (median) and has a fibrillose coating the same colour as the cap surface. Spores: 4.8-5.3 x 3.5-4 μm. Ellipsoidal to ovoid with a slightly thick wall and no germ pore. Hyaline. Dextrinoid, congophilous, cyanophilous and metachromatic. Basidia: 13-16 x 6–7.5 μm. Clavate. Smell: It has a distinct but soft flowery smell. [3]
The specific epithet flavus derives from the Latin flavus meaning yellow. [4] This refers to the colour of the mushrooms. [3]
The specimens studied were found in deciduous and bamboo forests in Laos during the rainy season of October to November where they were growing solitary on soil. [3]
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.
