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 [2] and contains over 80 recognised species, [3] 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.

Taxonomy

The genus was created in 1888 by the French mycologist Narcisse Théophile Patouillard. [4]

Due to the superficially similar features which many Leucocoprinus, Leucoagaricus and Lepiota species have these genera and the species within them have been subject to a great deal of reclassification over the years. One example of this is Leucoagaricus leucothites which has numerous synonyms formerly belonging to all three genera. [5]

These genera along with Cystolepiota , Chlorophyllum and Macrolepiota are often referred to as Lepiotoid mushrooms. Typical macroscopic characteristics include white spore prints, the presence of a stem ring formed from the partial veil and gills which are free from the stem. There are always exceptions to these details however. Flaky or woolly scales on the cap or stem of these mushrooms and a distinctly coloured central disc are common features amongst many species but are likewise observed in many other genera. Reliable identification of Lepiotoid mushrooms at the species level can be notoriously difficult. Many species can only reliably be distinguished by microscopic details and chemical reagent tests. [6]

Species

Commonly known species include:

Many of these species have been documented growing in plant pots and greenhouses [7] [8] and so may have a worldwide distribution in captivity with introduction into the wild being possible where temperatures are suitable for these tropical species. Several of the best known species were originally described from greenhouses before ever being recorded in the wild. [9] [10] [11]

Habitat and distribution

Many Leucocoprinus species originate from tropical climates where they thrive in the hot and humid conditions of rainforests however species have now spread all over the world due to human activity. Numerous species in this genus were introduced to Europe by early explorers bringing exotic plants back from tropical climates which carried unseen fungal hitchhikers in the soil. As a result, new and unknown species of mushrooms began appearing in greenhouses and hothouses all over Europe which piqued the interest of budding new mycologists who sought to classify these strange new 'plants', as mushrooms were then considered to be. [12] Some Leucocoprinus species were observed in Europe in the 18th century before ever being found in the wild.

Leucocoprinus birnbaumii was first described in 1788 from an observation in a hothouse in Halifax, England. [9] In 1793 British botanist James Sowerby observed it growing at Wormleybury manor, [13] likely in the hothouses and greenhouses which contained plants from the East Indies and India. [14] Its specific epithet is named for Mr Birnbaum, a gardener who found the yellow mushrooms growing in greenhouses amongst pineapples in the Salmovský gardens in Prague in the 1830s. [15] [16] [17]

Leucocoprinus cretaceus was also first classified in 1788 by Pierre Bulliard from observations made in greenhouses and in planters under cold frames in France [10] however as Bulliard's illustration more closely matched that of L. cepistipes it caused confusion in the identification of these two species. [18] In 1871 the German botanist Otto Kuntze stated that the mushrooms grew in large numbers in gardens and greenhouses but did not appear too often. [19]

Leucocoprinus cepistipes has a more complicated history as it was routinely conflated with L. cretaceus due to the similarly white appearance or even considered to simply be a white version of L. birnbaumii before species classifications were better established. James Sowerby's detailed illustrations from 1796, [13] made from specimens found in bark beds around London, depict both a white and yellow species side by side which he considered to be 'undoubtedly the same species' saying that they 'differ in nothing but colour'. [20]

These species are still commonly found in greenhouses and plant pots in Europe and all over the world. Centuries of buying and selling tropical plants has created an effective distribution network for Leucocoprinus species as the conditions of greenhouses and indoor plant pots can mimic the warm and humid tropical conditions which these mushrooms require. Collecting exotic plants in botanical gardens may also help to spread these species. [7]

Other Leucocoprinus species such as L. ianthinus are also commonly observed growing in plant pots with this species being described from a barkbed in a hothouse in Kew Gardens in 1888. [21] Observations of this species are largely limited to plant pots [22] and it is unclear where it is native to. In some regions it may be warm enough for introduced Leucocoprinus species to survive in the wild or grow outside but in regions with cold winter temperatures their distribution is generally limited to plant pots and greenhouses. There are however also common Leucocoprinus species which grow in temperate climates like L. brebissonii which can be found outside in Europe and is especially common on the West coast of the United States [23] whereas L. fragilissimus is uncommon in Europe but common on the East coast of the United States. [24]

<i>Lepiota</i> Genus of fungi

Lepiota is a genus of gilled mushrooms in the family Agaricaceae. All Lepiota species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of Lepiota are currently recognized worldwide. Many species are poisonous, some lethally so.

<i>Leucocoprinus birnbaumii</i> 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. 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.

<i>Leucocoprinus cepistipes</i> Species of fungus

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.

<i>Leucoagaricus</i> Genus of fungi

Leucoagaricus is a genus of mushroom-forming fungi in the family Agaricaceae. As of March 2023 there are over 200 accepted species of Leucoagaricus with ongoing research into the genus adding several more each year. Leucocoprinus is a similar genus and considered by some sources to be indistinct from Leucoagaricus based on genetic data that demonstrates they are monophyletic. Species are separated into these genera based on macroscopic features such as cap striations in Leucocoprinus or the more persistent basidiocarps (mushrooms) of Leucoagaricus as well as microscopic features such as the lack of a germ pore in Leucoagaricus species. As a result of the similarities and disagreement on taxonomy, many of the species within these genera have formerly been classified in the other and may still be known by previous classifications. For instance the species Leucoagaricus gongylophorus is cultivated by fungus-growing ants but was formerly known as Leucocoprinus gongylophorus whilst other species cultivated by the lesser attine ants are still classified as undescribed Leucocoprinus species.

<i>Leucocoprinus brebissonii</i> Species of fungus

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.

<i>Leucocoprinus fragilissimus</i> Species of fungus

Leucocoprinus fragilissimus, commonly known as the fragile dapperling, is a species of gilled mushroom in the family Agaricaceae.

<i>Leucocoprinus cretaceus</i> Species of fungus

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.

<i>Leucoagaricus badhamii</i> Species of fungus

Leucoagaricus badhamii is a species of fungus in the family Agaricaceae and genus Leucoagaricus. The flesh of this mushroom turns blood red when cut or bruised, hence its common name of blushing dapperling. These damaged areas may eventually turn brown or black and likewise the mushroom may discolour brown or black with age. All parts of the flesh display red staining aiding in identification.

<i>Leucocoprinus ianthinus</i> Species of fungus

Leucocoprinus ianthinus is a species of mushroom producing fungus in the family Agaricaceae. Like several 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. It is not seen in plant pots with the same kind of regularity as the well known Leucocoprinus birnbaumii and not seen in the wild as frequently as Leucocoprinus brebissonii.

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.
