Leucocoprinus flavescens is a species of mushroom-producing fungus in the family Agaricaceae. [1] [2]
It was first described in 1907 by the American mycologist Andrew Price Morgan who classified it as Lepiota flavescens [3] and reclassified as Leucocoprinus flavescens by the American botanist and mycologist Helen Vandervort Smith in 1981. [4]
Leucocoprinus flavescens is a small mushroom with very thin white to pale yellow flesh.
Cap: 1–2.5cm or up to 4cm at the extreme. Ovoid to campanulate (bell shaped) with an umbo before flattening or becoming convex with age. The surface is pale greenish-yellow and is covered in fine powdery scales with smooth striations whilst the central disk is brownish but smooth. Stem: 2–6 cm and 1–2 mm in thickness with a slightly swollen base of 3–5 mm thick where white mycelium may be present. The stem surface is pale sulphur-yellow and is likewise covered with fine powdery scales like the cap though these may disappear with age leaving the stem smooth and it sometimes discolours reddish-brown. The fragile stem ring is pale yellow and located towards the top of the stem (superior) but it may disappear. Gills: Free, close and yellowish. Spore print: White. Spores: Ellipsoid, smooth. 4.8–6.6 (7.2) × (3.5) 4.9–5.5 μm. Taste: Bitter. Smell: Indistinct. [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. [6]
L. flavescens is not very well known and not often recorded. 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. The limited number of observations which have been made suggest the species is uncommon but that it has a widespread distribution in the United States with observations also made in Costa Rica. [7]
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. However, in temperate regions, it frequently occurs in greenhouses and flowerpots, hence its common names of flowerpot parasol and plantpot dapperling. It is considered to be toxic if consumed.
Leucocoprinus is a genus of fungi in the family Agaricaceae. Its best-known member is the distinctive yellow mushroom Leucocoprinus birnbaumii, which is found in plant pots and greenhouses worldwide. The type species is Leucocoprinus cepistipes. The genus has a widespread distribution and contains over 80 recognised species, however many of these species are very scarcely recorded and little known with only a small number of Leucocoprinus species which are commonly observed. The majority of the species in this genus are exclusive to tropical environments however numerous species have become a common sight in plant pots and greenhouses resulting in them becoming well known worldwide.
Leucocoprinus cepistipes, is a species of fungus in the family Agaricaceae. It is typically found on wood debris, such as wood chips but may also grow in potted plants or greenhouses. Typical characteristics include a fine-scaled bell-shaped cap, a partial veil, and a tendency to bruise a yellow to brown when handled.
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 and may also be found in Asia.
Leucocoprinus fragilissimus, commonly known as the fragile dapperling, is a species of gilled mushroom in the family Agaricaceae.
Leucocoprinus cretaceus is a species of mushroom producing fungus in the family Agaricaceae. It is likely tropical in origin although it was first documented in Europe where it was often found growing in greenhouses and bark beds. However many early observations conflate this species with Leucocoprinus birnbaumii or Leucocoprinus cepistipes despite sharing only some superficial similarities. This fungus is quite versatile even for a saprotroph and is often found growing in clusters on woodchips, sawdust and compost heaps as well as directly from the ground or on trees. It may also appear in plant pots and greenhouses in colder countries in which it is not well equipped to survive outside.
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.
